    CERTIFIED FOR PUBLICATION
    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    SIXTH APPELLATE DISTRICT
    PAM PIPITONE,                                      H041468
    (Monterey County
    Plaintiff and Appellant,                   Super. Ct. No. M114411)
    v.
    DON WILLIAMS et al.,
    Defendants and Respondents.
    This action arises from the murder of Ryann Bunnell, the daughter of plaintiff and
    appellant Pam Pipitone. Ryann was killed by her husband, Jesse Crow, who later killed
    himself in jail while awaiting murder charges.1 Defendants and respondents Deane
    Crow, M.D. and Don Williams, M.D. separately saw and treated Ryann several months
    before her death for injuries she sustained when Jesse ran over her foot with his truck. At
    the time, Ryann did not reveal the true origin of her injury to Dr. Crow or Dr. Williams.
    Pipitone brought this wrongful death action against Dr. Crow and Dr. Williams for
    failure to report alleged, suspected abuse to the authorities as required by Penal Code
    section 11160. The trial court granted respondents’ separate motions for summary
    judgment, each on the independent grounds of duty and causation. The court also granted
    Dr. Williams’ motion on a third ground, the affirmative defense of equitable estoppel.
    1
    Although it is generally accepted that Jesse Crow killed Ryann Bunnell, we note
    that his suicide came before he could be tried and found guilty beyond a reasonable
    doubt.
    Pipitone appeals from the court’s entry of summary judgment against her. She argues
    that she raised triable issues of fact as to duty and causation.
    We conclude that the trial court correctly found no triable issue of fact as to both
    elements of duty and causation, for both respondents. Because breach of duty and
    causation are necessary elements of a wrongful death action predicated on alleged
    violations of Penal Code section 11160, we will affirm the judgments in favor of
    Dr. Williams and Dr. Crow.
    FACTUAL AND PROCEDURAL BACKGROUND2
    A. Defendants’ Medical Treatment of Ryann and the Circumstances of Her Murder
    Ryann Bunnell began dating Jessie Crow in July 2009 and they married the
    following month. It was only about six months later that Jesse brutally murdered Ryann,
    and with the assistance of several other individuals,3 dismembered her and dumped her
    body parts into the San Francisco Bay.
    Dr. Crow is a retired physician and the father of Jesse Crow. Dr. Crow was aware
    that Jesse had a history of fights and arrests, at least one involving brandishing a gun on
    the highway; he had hired a lawyer for his son as a result of such incidents. Dr. Crow
    met Ryann for the first time after the couple married and saw her fewer than 10 times
    before her death. One of those occasions took place in the early hours of the morning of
    October 23, 2009 when Dr. Crow received a phone call from his son. The call woke
    Dr. Crow. Jesse asked his dad to come to his house because Ryann was injured.
    2
    For purposes of this background we only include facts properly in the record.
    We note that Pipitone failed to limit the factual summary in her opening brief “to matters
    in the record” and further failed to support factual references “by a citation to the volume
    and page number of the record where the matter appears.” (Cal. Rules of Court, rule
    8.204(a)(2)(C), 8.204 (a)(1)(C), italics added.)
    3
    The “others” who helped Jesse dispose of Ryann’s body after the murder are
    named in a separate cause of action in the underlying complaint but are not parties to this
    appeal.
    2
    Dr. Crow arrived about five minutes later. Ryann was sitting on the couch and in
    apparent pain. Both Jesse and Ryann were noticeably intoxicated. Ryann complained of
    an ankle or foot injury and told Dr. Crow that she had been run over by a truck. Ryann or
    Jesse also conveyed that she had been injured when she tried to climb into Jesse’s truck
    and fell down as he was backing up.
    Dr. Crow briefly examined Ryann and noted abrasions on her foot, ankle, and
    shoulder. He did not ask Ryann anything else about how she had been injured but
    suspected that she might have a broken bone. Dr. Crow left for his house and returned to
    bring Ryann over-the-counter pain medication. Between the two visits, Dr. Crow spent
    approximately 10 minutes with Ryann. He did not advise Ryann about seeking further
    medical care.
    That same morning, Dr. Crow’s wife went to Jesse’s house and arranged for
    Ryann to see Dr. Williams. Dr. Williams is an orthopedic surgeon in private practice.
    About 10 years earlier, Dr. Williams had employed Dr. Crow’s wife as a radiology
    technician. He remained friendly with the Crows and saw them occasionally through
    their professional network. He had known Jesse when Jesse was a teenager.
    Dr. Williams did not personally know Ryann.
    On October 23, 2009, Ryann, accompanied by Jesse, received treatment at
    Dr. William’s medical office. Ryann told Dr. Williams that a truck had run over her foot
    but that she and Jesse were drunk at the time and did not get the license plate or know the
    identity of the driver. Dr. Williams’ examination confirmed a potential hairline fracture
    in Ryann’s right foot, as well as bruises and abrasions to her foot, leg and hip, and a
    possible partial ligament tear in her left knee. Ryann’s injuries were consistent with her
    report of the accident. Though Ryann was alone with Dr. Williams and his staff for part
    of the exam, during the x-ray, Ryann did not offer more details about the accident or
    suggest that she was a victim of abuse. Nor did Dr. Williams probe further.
    3
    Dr. Williams suggested a cast boot and did not see Ryann again, though a week later he
    prescribed her Valium over the phone.
    Several days after Ryann’s treatment by Doctors Crow and Williams, Pipitone
    learned from her other daughter, Ryann’s sister, that Jesse had run over Ryann’s foot.
    Pipitone thought that Jesse should pay Ryann $5,000 toward her medical bills and lost
    earnings. Ryann conveyed the idea to Jesse, who purportedly agreed provided that they
    sign a contract stating the truck incident was an accident. A hand-written agreement was
    drafted, stating in relevant part that on October 23, 2009 Jesse “accidentally hit” Ryann
    with his vehicle, and instead of going to court for damages, both parties had agreed on
    payment of $5,000 by Jesse to Ryann “to cover the costs incurred as a result of the
    accident.” Jesse, with contribution from Dr. Crow, paid Ryann. Pipitone signed the
    agreement as a witness.
    The same day that Pipitone witnessed the agreement framing the truck incident as
    an accident, Pipitone took Ryann to the hospital emergency room for her foot. Pipitone
    hoped that Ryann would report the incident to the hospital staff during the health history
    intake.4 Pipitone was present while Ryann responded to the health history questions, but
    Ryann did not report the abuse.
    After other abusive acts perpetrated by Jesse, and notwithstanding the
    “agreement,” Pipitone called the police to report that Jesse had “broken Ryann’s leg” and
    that Ryann was suffering abuse and was afraid. Ryann’s sister made similar reports to
    the police. On December 23, 2009, an officer with the Salinas Police Department,
    Patrick Haney, dispatched to interview Ryann. In his deposition, Officer Haney testified
    that Ryann was not cooperative during the interview. Ryann admitted that her husband
    had deliberately run over her and that it took place in Monterey. She admitted that she
    4
    Piptone is a licensed vocational nurse who had been employed at the hospital.
    She knew that the health history process would provide Ryann a chance to disclose
    abuse.
    4
    felt threatened by her husband, that he had “guns and a lot of illegal things” and would
    come after her and her family if she said anything. She did not want to give the officer
    details and indicated she did not want to talk with law enforcement. Officer Haney gave
    Ryann a resource pamphlet for domestic violence victims. He forwarded his report to the
    Monterey Police Department and Monterey County Sheriff’s Department. No further
    police intervention occurred.
    On February 2, 2009, Ryann’s family reported her missing. Her murder took
    place on or about January 30, 2009.
    B. Pipitone’s Wrongful Death Action
    Pipitone brings this civil action as the sole surviving heir of the decedent. In the
    second cause of action of the complaint, Pipitone alleges that Dr. Crow treated Ryann for
    injuries from the truck incident, including a fracture of the right foot and numerous open
    and obvious bruises, abrasions, cuts and swelling to her right leg and foot. She alleges
    that Dr. Crow knew or should have known that Ryann’s injuries were the result of
    assaultive or abusive conduct because of his “knowledge of violent behavior on part of
    Jessie5 Crow in the past, the nature of the injuries, and/or because of information received
    as to the cause of the injuries,” and that he failed to make a report to law enforcement in
    violation of Penal Code section 11160. She also alleges that he “undertook a confidential
    relationship” with his son to protect Jesse from the consequences of his domestic
    violence and to conceal the nature of the domestic violence incident. In the third cause of
    action, Pipitone alleges that Dr. Crow’s conduct in failing to make a report to law
    enforcement was willful and intentional.
    In the fourth and fifth causes of action of the complaint, Pipitone brings identical
    allegations against Dr. Williams but argues that the “confidential relationship” was
    5
    The spelling of names varies across the complaint and other documents in the
    record. Jesse Crow is alternately spelled “Jessie” Crow; Ryann Bunnell is alternately
    spelled “Ryan” Bunnell or referred to as “Ryan Crow.”
    5
    between Dr. Williams and Dr. Crow and/or Jesse Crow. She also alleges that Dr.
    Williams’ knowledge of the cause of the injury was “because of Defendant Dean Crow’s
    knowledge of violent behavior on part of Jessie Crow in the past, the nature of the
    injuries, and/or because of information received as to the cause of the injuries.”
    Both respondents answered the complaint and generally denied the allegations.
    B. Summary Judgment Proceedings
    1. Dr. Williams’ Motion for Summary Judgment
    Dr. Williams moved for summary judgment on three grounds: (1) no breach of
    any duty by Dr. Williams; (2) assuming liability, no causation; and (3) Pipitone’s
    wrongful conduct facilitating a paid arrangement to cover up the abuse that she asserted
    Dr. Williams should have discovered and reported estopped her from asserting claims
    against him.
    In support of the motion, Dr. Williams submitted his declaration,6 Pipitone’s
    responses to requests for admission, and deposition testimony of witnesses. These
    included: Pipitone; members of Dr. Williams’ office staff; nursing staff at Salinas Valley
    Memorial Hospital; and Officer Haney, who interviewed Ryann in December 2009.
    Dr. Williams argued that Pipitone could not establish breach of any mandatory duty
    because there was no evidence that Dr. Williams knew or reasonably suspected that
    Ryann was a victim of domestic abuse. Even if evidence existed to establish duty,
    Dr. Williams argued there could be no causation because Pipitone herself reported the
    same abuse to the police and the subsequent investigation did not change the ultimate,
    terrible outcome.
    6
    While the motion was pending, Dr. Williams filed an errata and amended
    declaration ostensibly correcting the record as to whether he knew that Dr. Crow also had
    tended to Ryann’s injury.
    6
    2. Dr. Crow’s Motion for Summary Judgment
    Dr. Crow moved for summary judgment, or in the alternative, summary
    adjudication of the two causes of action filed against him. He argued that there was no
    mandatory duty to report the alleged domestic violence because the night he saw Ryann
    for her injuries he was acting as a parent and not in his professional medical capacity, and
    because there was no evidence that he knew or reasonably suspected domestic violence.
    Dr. Crow also argued that Pipitone could offer no evidence that a mandatory reporting
    failure was the proximate cause of Ryann’s death because many intervening events,
    dependent on discretionary acts, took place in the time that transpired between
    Dr. Crow’s treatment of Ryann and her murder. In support of his motion, Dr. Crow
    proffered his own deposition testimony, Pipitone’s deposition testimony, that of a Salinas
    Valley Memorial Hospital nurse, and that of Officer Haney.
    3. Pipitone’s Opposition to Respondents’ Motions
    Pipitone filed a joint response to the memoranda of points and authorities of
    Dr. Williams and Dr. Crow, and a separate response to each separate statement of facts.
    In addition to Penal Code section 11160, Pipitone argued that the action against
    Doctors Crow and Williams was predicated upon Penal Code section 11161.7 In her
    opposition, Pipitone argued that there were triable issues of fact as to whether each doctor
    should reasonably have suspected that Ryann’s injuries resulted from domestic violence,
    and that by failing to offer expert testimony in support of the motions for summary
    judgment, Doctors Crow and Williams could not meet their initial burdens on the issue of
    duty. Pipitone also argued that a failure to exercise due care was presumptively
    established under Evidence Code section 669.8
    7
    Pipitone’s complaint does not allege a violation of Penal Code section 11161,
    only Penal Code section 11160.
    8
    Evidence Code section 669, subdivision (a) establishes a rebuttable presumption
    that a person failed to exercise due care if that person: (1) violated a statute, ordinance, or
    7
    Pipitone argued that the causal link between non-intervention in a domestic
    violence situation and escalating violence had been definitively established. In support of
    both arguments, Pipitone submitted the expert declaration of Linda Barnard, Ph.D
    (Barnard Declaration), a marriage family therapist and doctor of counselor education
    specializing in domestic violence and related trauma issues.
    Dr. Barnard’s curriculum vitae referenced extensive experience as a presenter and
    expert witness in the domestic violence field. In her declaration, Dr. Barnard stated that
    she “reviewed and considered” the deposition transcripts of both doctors and the
    statements attributed to them. Dr. Barnard opined generally that the mandatory reporting
    provisions establish a minimum standard of care for health care providers, that without
    intervention violence “usually escalates in both frequency and severity resulting in repeat
    visits to healthcare systems or death,” and that health care providers serve as
    “‘gatekeepers’” to identity and report abuse where family members and the abused
    themselves may not. Such reports by trained professionals “tend to receive more attention
    from those in a position to act upon the report.”
    Dr. Barnard also opined that each doctor “had or should have had at least a
    reasonable suspicion that the incident of on or about October 22, 2009 was assaultive or
    abusive conduct.” With regard to Dr. Crow, this included that he “knew the injury was
    suffered by an instrumentality controlled by [Ryann’s] husband” and that he had made
    statements “evidencing a knowledge of violent propensities on the part of Jessie Crow.”
    With regard to Dr. Williams, this included that he knew the descriptions of the truck
    incident “provided by the husband and wife were inconsistent and lacking in detail” and
    he “knew that Jessie [sic] mother provided x-ray services, and thought it was odd they did
    regulation of a public entity; (2) the violation proximately caused death or injury to
    person or property; (3) the death or injury resulted from an occurrence of the nature
    which the statute, ordinance, or regulation was designed to prevent; and (4) the person
    suffering the death or the injury to his person or property was one of the class of persons
    for whose protection the statute, ordinance, or regulation was adopted.
    8
    not go to his mother for those services.” Dr. Barnard further opined that the failure of
    Dr. Crow and Dr. Williams to report the information to law enforcement “increased the
    risk of injury to Ryann Bunnell by way of assault and/or battery to an unusual degree,”
    that “the murder of Ryann Bunnell is directly related to the failure to report the incident
    of on or about October 22, 2009,” and that compliance with the mandatory reporting
    sections of the Penal Code “would more likely than not have prevented the murder of
    Ryann Bunnell.”
    Further in support of her opposition, Pipitone presented varying accounts, from
    deposition testimony and other statements taken in the case, of each respondent’s
    treatment of Ryann and familiarity with the circumstances of her injuries. For example,
    she cited various versions of Dr. Crow’s visit with Ryann and Jesse on October 23, 2009
    which, taken together, appear to present consistency and credibility issues. First, Pipitone
    cited Dr. Crow’s interviews with law enforcement during the murder investigation, as
    recounted in the declaration of Ryan McGuirk, Supervising Investigator with the
    Monterey County District Attorney’s Office (McGuirk Declaration). Next Pipitone
    offered a summary contained in correspondence from Dr. Crow’s former counsel to
    plaintiff’s counsel, as well as a statement by Dr. Crow’s former counsel in opposition to a
    motion to compel. Pipitone also submitted excerpts of Dr. Crow’s deposition testimony
    in which his responses pertaining to the morning after the truck incident appear fractured
    and convoluted. Finally, Pipitone submitted the declaration of Ryann’s sister, Rochelle
    Bunnell (Bunnell Declaration), in which Ms. Bunnell described her visit to see Ryann
    that same morning and her observations of Dr. Crow. Pipitone also presented varying
    accounts of Dr. Crow’s actions in relation to the $5,000 payoff.
    Similarly with respect to Dr. Williams, Pipitone pointed to inconsistencies
    between Dr. Williams’ deposition testimony, his declaration submitted in support of the
    motion for summary judgment, and the recorded statement that he provided during the
    murder investigation, as recounted in the McGuirk Declaration.
    9
    4. Objections to Pipitone’s Evidence
    Dr. Williams and Dr. Crow each objected to large portions of Pipitone’s
    evidentiary submissions, many of which the trial court sustained. Pipitone did not contest
    the objections at the trial court hearing or raise the trial court’s evidentiary rulings in the
    present appeal. To the extent that the exclusion of certain evidence is pertinent to our
    discussion below, we summarize those objections and the trial court’s rulings.
    a. Barnard Declaration
    Both respondents objected to the expert declaration of Linda Barnard, Ph.D, in its
    entirety as well as to numerous paragraphs therein. The objections may be summarized
    as follows. As a marriage and family counselor with a Ph.D in counselor education,
    Dr. Barnard was not qualified to render opinions on the standard of care applicable to
    medical doctors presented with a foot injury. The opinions lacked foundation and were
    not based on matters upon which an expert would ordinarily rely. The opinions were
    highly speculative and conclusory, failing to provide a basis in reasoned explanation or
    verifiable facts. The trial court separately sustained Dr. Williams and Dr. Crow’s
    objections to the entire Barnard Declaration.
    b. Pipitone Declaration
    Dr. Crow objected to several paragraphs of the declaration of appellant offered in
    support of her opposition to the motions for summary judgment on the grounds of
    hearsay without exception and improper lay opinion. For example, in reference to
    Pipitone’s conversations with her daughter and Jesse Crow on the morning of
    October 23, 2009, immediately after the truck incident, she stated in paragraph 9: “I
    asked [Ryann] if the police came and Ryann said they were not called because she did not
    get a license plate number,” and in paragraph 15: “I asked Jesse Crow why he did not
    take Ryann to the hospital and he said because his dad was an emergency room doctor.
    ‘My dad always fixes us up.’ ” In paragraph 26, in reference to the $5,000 payment
    scheme, Pipitone stated: “Jesse then said that ‘My dad will only give half the money
    10
    unless there is a contract and he (Dr. Crow) wants it to say it was an accident.’ ” The trial
    court sustained these and all of the objections to the Pipitone declaration.
    c. Bunnell Declaration
    Dr. Crow objected to numerous paragraphs of the declaration of Rochelle Bunnell
    on the same grounds as to the Pipitone Declaration. Most pertinent here are
    Ms. Bunnell’s observations from the morning of October 23, 2009, when she went to the
    house around 8:00 a.m. to check on her sister:
    “Dr. Crow went to examine Ryann and lifted her bandage. Dr. Crow indicated her
    leg was not broken but her foot was. Dr. Crow asked Ryann if she was in pain and
    Ryann said ‘yes.’ He then glared at Jessie, shaking his head side to side. Dr. Crow also
    told Jessie to call Dr. Williams, telling Jessie that Dr. Williams will get you in and take
    X-rays. Based upon the words and manner of the statements, I understood this as
    confirmation that Dr. Crow was aware of a prior communication with Dr. Williams.
    Dr. Williams was described as a friend of the Crows. [¶] . . . [¶] “It appeared to me that
    Jesse and Dr. Crow had discussed earlier what to do.”
    In paragraph 27, Ms. Bunnell described what she heard from Ryann about the
    $5,000 payment:
    “Ryann told me that our mom and dad were helping her move out and that our
    mom and dad wanted Jesse to pay $5,000 for medical bills and missed work. Ryann
    indicated Jesse would only agree if it was put in writing that her injuries were caused by
    an accident. Ryann told me that Dr. Crow had come by and paid $2,500 of the agreed
    upon amount of $5,000. Ryann also told me that Dr. Crow and Jesse wanted a contract
    written before they would give her the rest of the $5,000.”
    The trial court sustained these and all of the objections to the Bunnell declaration.
    d. McGuirk Declaration
    Dr. Crow also objected to portions of the declaration of Ryan McGuirk,
    supervising investigator with the Monterey County District Attorney’s Office, in which
    11
    McGuirk described two interviews taken during the murder investigation. In paragraph 6,
    McGuirk stated:
    “During the course of the investigation, in an interview taken on January 30, 2010,
    Dr. Crow told law enforcement that at the time of the prior truck injury incident, he was
    at home with his wife, Jessie Crow arrived at their home in an excited state and said they
    had to follow him back to his house. He told law enforcement in that interview that both
    he and his wife followed Jesse back to Jessie’s house and upon entering they found Jessie
    and Ryann in a screaming argument. He said at one point that he had no idea why they
    were arguing and at another point both were accusing of stalking each other. He said no
    one appeared hurt. He said he did not want to be involved so he just left.”
    Also in paragraph 6, McGuirk stated:
    “On February 4, 2010, Dr. Crow was again interviewed by law enforcement, this
    time in a recorded interview. I was the primary interviewer. In that recorded interview
    he was asked about his son Jessie Crow. About his son, he told law enforcement that it
    was typical for Jessie to get agitated and that he had ‘episodes’ of agitation. He told them
    that ‘if something doesn’t go right, he becomes quite vicious and fights.’ He also
    confirmed that Jessie “gets angry on a whim.”
    Dr. Crow objected to these statements on the grounds of hearsay without
    exception, improper lay opinion, lack of personal knowledge, and that the asserted
    “beliefs, opinions and conclusions” are not competent evidence. The trial court sustained
    these objections.
    5. Trial Court’s Ruling on the Motions
    After a joint hearing, the trial court granted both motions for summary judgment.
    In its order on Dr. Crow’s motion, the court did not specify the grounds for granting the
    motion. At the hearing, the court had indicated that it found Dr. Crow to be acting as a
    parent, and not in his capacity as a physician, and that even if there was a duty to act, the
    court found no triable issues of fact as to causation.
    12
    As to Dr. Williams, the court determined first that Pipitone had not put forth
    admissible evidence raising a triable issue of fact on the element of duty. That is,
    “Dr. Williams was not presented with any history, clinical information, or ascertainable
    injury that would oblige him to suspect, and correspondingly, report spousal abuse.”
    Second, the court determined that the evidence was insufficient to create a triable
    question of fact as to causation: “There was no causal nexus between Dr. Williams’
    conduct and the absence of a report of spousal abuse: Spousal abuse was, in fact,
    reported and investigated by law enforcement personnel during the lifetime of Plaintiff’s
    Decedent.” Third, the court determined that Pipitone was barred from proceeding with
    her causes of action against Dr. Williams under the doctrine of estoppel.
    DISCUSSION
    A. Standard of Review
    A trial court properly grants a motion for summary judgment when there is no
    triable issue of material fact and the moving party is entitled to a judgment as a matter of
    law. (Code Civ. Proc., § 437c.) A triable issue of fact exists only if “the evidence would
    allow a reasonable trier of fact to find the underlying fact in favor of the party opposing
    the motion in accordance with the applicable standard of proof.” (Aguilar v. Atlantic
    Richfield Co. (2001) 
    25 Cal. 4th 826
    , 850, fn. omitted.)
    A defendant moving for summary judgment must show either that the plaintiff
    “ ‘ “has not established, and cannot reasonably expect to establish,” ’ the elements of his
    or her cause of action,” or that there is a complete defense to that cause of action.
    (Ennabe v. Manosa (2014) 
    58 Cal. 4th 697
    , 705 (Ennabe), quoting State of California v.
    Allstate Ins. Co. (2009) 
    45 Cal. 4th 1008
    , 1017-11018; Code Civ. Proc., § 437c,
    subd. (p)(2).) Support for the motion must take the form of evidence, including
    affidavits, declarations, admissions, and depositions. (Code Civ. Proc., § 437c,
    subd. (b).) Once the defendant makes this initial showing, the burden shifts to the
    plaintiff to set forth “specific facts” beyond the pleadings that show a triable issue of one
    13
    or more material facts as to the cause of action or defense. (Code Civ. Proc., § 437c,
    subd. (p)(2).)
    We review a motion for summary judgment de novo. (Wilson v. 21st Century Ins.
    Co. (2007) 
    42 Cal. 4th 713
    , 717 (Wilson).) We consider only the facts that were properly
    before the trial court when it ruled on the motion and apply the same three-step analysis
    as the trial court: first we “identify the issues framed by the pleadings;” next we
    “determine whether the moving party's showing has satisfied his burden of proof and
    justifies a judgment in movant's favor;” and finally we “determine whether the opposition
    demonstrates the existence of a triable issue of material fact.” (Inter Mountain Mortg.,
    Inc. v. Sulimen (2000) 
    78 Cal. App. 4th 1434
    , 1439, quoting Brantley v. Pisaro (1996) 
    42 Cal. App. 4th 1591
    , 1601-1602.) In doing so, we liberally construe the evidence in support
    of the party opposing summary judgment and resolve doubts concerning the evidence in
    favor of that party. 
    (Wilson, supra
    , 42 Cal.4th at p.716-717; 
    Ennabe, supra
    , 
    58 Cal. 4th 697
    , 705.)
    B. Issues Framed by the Pleadings
    Pipitone asserts that she presented evidence sufficient to create a triable issue of
    fact that each doctor knew or reasonably suspected the true nature of Ryann’s injuries on
    October 23, 2009, breached his duty to report pursuant to Penal Code section 11160 or
    Penal Code section 11161, and that this breach directly contributed to Ryann’s death. As
    a preliminary matter, we find that Pipitone’s failure to identify Penal Code section 11161
    in her complaint did not preclude her from raising it as a source of duty in her opposition
    to the motions for summary judgment.
    In relevant part, Penal Code section 11160 mandates a report to law enforcement
    “immediately or as soon as practically possible” when any health practitioner, acting in
    his or her professional capacity or within the scope of employment, provides medical
    services for a patient “whom he or she knows or reasonably suspects” is “suffering from
    any wound or other physical injury … where the injury is the result of assaultive or
    14
    abusive conduct.” Penal Code section 11161 imposes the identical duty and applies more
    broadly to “every physician or surgeon who has under his or her charge or care any
    person” suffering from injuries inflicted in the manner described in section 11160.
    (Landeros v. Flood (1976) 
    17 Cal. 3d 399
    , 407 (Landeros).) The facts pleaded in
    Pipitone’s complaint were sufficient to put Dr. Crow on notice of the allegations against
    him regardless of whether his alleged duty arose out of Penal Code section 11160 or
    Penal Code 11161.9 Further to the point, as we will explain in detail below, under neither
    statutory section has Pipitone met her burden to demonstrate a triable issue of material
    fact.
    C. Evidentiary Issues
    Respondents urge that we review the trial court’s evidentiary rulings for abuse of
    discretion. Dr. Crow moreover argues that Pipitone waived any appeal of the evidentiary
    rulings by failing to challenge those rulings in her opening brief. Dr. Crow and
    Dr. Williams also criticize Pipitone’s unqualified discussion in her appellate brief of
    evidence that the trial court had excluded, including the expert declaration of Dr.
    Barnard.
    Pipitone replies that the proper standard is de novo review of the trial court’s
    evidentiary rulings, and that her evidentiary showing is “sufficiently strong” without the
    expert declaration (and, presumably, other evidence to which the trial court sustained
    objections). We consider both evidentiary issues: (1) by what standard do we review the
    trial court’s evidentiary rulings on summary judgment; and (2) did Pipitone waive any
    challenge to the excluded evidence?
    9
    At the summary judgment hearing, Pipitone’s counsel requested to amend the
    plaintiff’s complaint “to the extent that the trial court doesn’t find that we factually
    alleged [Penal Code section 11161], even though we didn’t cite the particular code
    section.” The trial court accepted the argument and noted Penal Code section 11161,
    alongside Penal Code section 11160, in its oral findings.
    15
    As to the standard of review, we look to the California Supreme Court for
    guidance. In Reid v. Google, Inc. (2010) 
    50 Cal. 4th 512
    (Reid), the court addressed the
    proper treatment on appeal of a trial court’s failure to rule on evidentiary objections when
    adjudicating a summary judgment. In the context of resolving that issue, the appellate
    court in Reid had deemed it proper to review the evidentiary objections on the merits:
    “ ‘Because summary judgment is decided entirely on the papers, and presents only a
    question of law, it affords very few occasions, if any, for truly discretionary rulings on
    questions of evidence. Nor is the trial court often, if ever, in a better position than a
    reviewing court to weigh the discretionary factors.’ ” (Id. at p. 535 [quoting the opinion
    of the appellate court].)
    The Supreme Court agreed with the appellate court that application of a de novo
    review standard was appropriate under the particular circumstances of the case but
    refrained from deciding “generally” which standard of review applies to a trial court’s
    rulings on evidentiary objections based only on the papers in summary judgment
    proceedings. (Reid, 50 Cal.4th at p. 535.) Even though the Court did not foreclose
    application of the abuse of discretion standard, we interpret Reid’s practical effect on
    review of a summary judgment, in which evidentiary issues, and all issues, are decided
    on papers alone, to be the application of de novo review.10
    10
    To the extent that appellate courts have continued to review for abuse of
    discretion a trial court’s rulings on evidentiary objections based on the papers in
    summary judgment proceedings (see, e.g., Jones v. Wachovia Bank (2014) 
    230 Cal. App. 4th 935
    , 951 [reviewing evidentiary objections on summary judgment for abuse
    of discretion and citing other courts of appeal that did the same]), we diverge and adhere
    to the reasoning set forth in Reid.
    16
    Here, unlike in Reid, the trial court ruled on respondents’ evidentiary objections.
    Because the rulings were determined on the papers and based on questions of law such as
    hearsay, we find that de novo review is proper in this context.11
    As to whether we refrain from considering evidence to which the trial court
    sustained objections, which rulings the appellant has not directly challenged on appeal,12
    we refer to our earlier decision in Mamou v. Trendwest Resorts, Inc. (2008) 
    165 Cal. App. 4th 686
    (Mamou). There we explained that it is not the role of the appellate
    court to “grant conclusive effect to the trial court’s treatment of the evidence before it,
    however patently erroneous that treatment may be.” (Id. at p. 711.) Quite the opposite:
    “if a party’s position depends on inadmissible evidence admitted over a proper
    objection,” or conversely if a party was prejudiced by the exclusion of admissible
    evidence, “a reviewing court would be empowered, and indeed obliged, to acknowledge
    the error” and review the evidence. (Ibid.) Though it is often stated that “ ‘[w]e must
    “consider [] all the evidence set forth in the moving and opposition papers except that to
    which objections have been made and sustained” ’ ” (ibid., quoting Reeves v. Safeway
    (2004) 
    121 Cal. App. 4th 95
    , 106-107 & Guz v. Bechtel National Inc. (2000) 
    24 Cal. 4th 317
    , 334), we conclude that a more accurate statement of our review of a summary
    11
    A more recent California Supreme Court decision regarding a pretrial
    evidentiary challenge to expert testimony is also instructive. In Sargon Enterprises, Inc.
    v. University of Southern Cal. (2012) 
    55 Cal. 4th 747
    , 773, the court held that in the
    context of pretrial proceedings, the trial court’s ruling excluding expert testimony is
    reviewed for abuse of discretion “[e]xcept to the extent the trial court bases its ruling on a
    conclusion of law.”
    12
    There is no question that Pipitone’s opening brief on appeal should have
    denoted which evidence in her moving papers had been excluded based on objections
    sustained by the trial court. Even so, each respondent has had the opportunity to address
    his objections raised and sustained below, and we consider the issue of the evidentiary
    rulings to be properly before this court as part and parcel of the appeals from the
    summary judgments.
    17
    judgment is that we consider all the evidence set forth in the moving and opposition
    papers except that to which objections have been made and properly sustained.13
    We therefore do not accept the argument that because Pipitone failed to expressly
    challenge the trial court’s evidentiary rulings excluding portions of the declarations and
    the entirety of Pipitone’s expert report, we must defer to those rulings without
    considering whether the trial court’s exclusion of potentially material evidence was
    proper.
    D. Summary Judgment was Proper as to Both Dr. Crow and Dr. Williams
    1. Dr. Crow’s Statutory Duty to Report Suspected Abuse
    Several factors must be in place in order to trigger a physician’s mandatory
    reporting duty under Penal Code section 11160. Dr. Crow’s motion for summary
    judgment focused on two of these factors: (1) the physician must be “acting in his or her
    professional capacity or within the scope of employment” when providing medical
    services for a patient, and (2) he must “know[] or reasonably suspect[]” the patient’s
    injury is the result of assault or abuse. (Pen. Code, § 11160, subd. (a).) Even for a
    physician acting outside of his professional capacity or scope of employment, the second
    factor is a prerequisite to trigger the mandatory reporting duty. (Pen. Code, § 11161.)
    Penal Code section 11162.5, subdivision (d) defines whether a physician “[r]easonably
    suspects” abuse to mean “that it is objectively reasonable for a person to entertain a
    suspicion, based upon facts that could cause a reasonable person in a like position,
    drawing, when appropriate, on his or her training and experience, to suspect.”
    In support of his motion on the element of duty, Dr. Crow presented deposition
    testimony from his and Ms. Pipitone’s depositions, neither of which reference evidence
    13
    Indeed, as we explained in Mamou, the common refrain from Guz v. Bechtel
    National Inc. (2000) 
    24 Cal. 4th 317
    , 334 (on appeal from a summary judgment “[w]e
    must ‘consider [] all the evidence set forth in the moving and opposition papers except
    that to which objections have been made and sustained’ ”) has “proven to be among the
    more mischievous dicta in recent history.” (Mamou, 
    165 Cal. App. 4th 686
    , 711.)
    18
    or mention facts that suggest that at the time of the October 23, 2009, middle-of-the-night
    house call to his son’s house, he could have suspected, let alone knew, that Ryann’s foot
    injury was caused by Jesse’s intentional assault or abuse. Dr. Crow relied on the same
    deposition testimony to argue that he acted solely in his capacity as a parent, and
    therefore did not have a duty to report. Because we accept that Pipitone alleged duty
    under Penal Code section 11161, however, and Dr. Crow has not disputed that he was at
    the relevant time a physician caring for a person, we will not consider that evidence here.
    In opposition, Pipitone asserted a combination of evidence, pointing to various
    versions of Dr. Crow’s encounter with and provision of care for Ryann sometime in the
    early morning hours of October 23, 2009. Pipitone’s showing raises consistency and
    credibility issues for Dr. Crow but ultimately does not identify conflicting evidence to
    create a triable issue of fact as to whether he entertained a suspicion of abuse. (See Horn
    v. Cushman & Wakefield Western, Inc. (1999) 
    72 Cal. App. 4th 798
    , 807 (Horn) [“ ‘To
    avoid summary judgment, [appellant] “must do more than establish a prima facie case
    and deny the credibility of the [defendant's] witnesses.” [Citation.]’ ”]; Code Civ. Proc.,
    § 437c, subd. (e) [trial court may not deny summary judgment on grounds of credibility
    of witnesses furnishing declarations in support of the summary judgment].) A triable
    issue of fact can only be created by a conflict of evidence, not speculation or conjecture.
    (Horn, 72 Cal.App.4th at p. 807.)
    For example, Dr. Crow testified in deposition that a call from Jesse in the middle
    of the night woke him from his sleep and that he proceeded alone to Jesse’s house where
    he observed Ryann in her injured state and learned that she had been run over by a truck,
    specifically Jesse’s truck, as she tried to climb in. Dr. Crow’s deposition testimony also
    revealed that he was aware that Jesse had a history of fights and one or more violent or
    weapon-related altercations, and that he had hired a lawyer for his son, though he could
    not recall on how many occasions he had to hire a lawyer. The testimony gave no
    19
    indication of how close in time these incidents were to October 23, 2009 or if they ever
    involved intimate partner violence.14
    Pipitone offered another version of Dr. Crow’s story in the McGuirk Declaration,
    purportedly based on Dr. Crow’s interview with police on January 30, 2010, in which
    Dr. Crow and his wife together followed Jesse back to the house and found Jesse and
    Ryann in a screaming argument where no one appeared hurt. As previously noted, the
    trial court sustained Dr. Crow’s objections to this statement. We agree that the statement
    lacked personal knowledge because McGuirk merely retold what Dr. Crow “told law
    enforcement.”
    This was not the case, however, for the February 4, 2010 recorded interview in
    which McGuirk declared that he was the primary interviewer. According to McGuirk’s
    declaration, in this interview Dr. Crow revealed that Jesse had “episodes” of agitation,
    that “if something doesn’t go right, he becomes quite vicious and fights,” and that Jesse
    “gets angry on a whim.” If offered for their truth, these statements in the McGuirk
    Declaration were hearsay but should have been admitted under the exception for a party
    admission. (Evid. Code, § 1220; Colarossi v. Coty US Inc. (2002) 
    97 Cal. App. 4th 1142
    ,
    1150 [finding error in trial court’s exclusion of non-party’s declaration recounting a
    damaging statement made by a party opponent].) If offered not for its truth but to
    undermine the credibility of Dr. Crow’s deposition testimony, it should have been
    admitted as non-hearsay. It remains, however, insufficient to create a triable issue of
    material fact. Drawing all reasonable inferences in Pipitone’s favor, Dr. Crow’s
    statement about his son may cause speculation; but it does not create conflicting evidence
    14
    Pipitone contends that Dr. Crow admitted in deposition to knowing of another
    arrest in Oregon in which Jesse purportedly harassed and urinated on a woman. Pipitone
    provides no citation to the record, and our detailed review of the record revealed no
    mention of this incident. We will disregard this and other factual statements by Pipitone
    that lack appropriate citation to the record. (See Cal. Rules of Court, rule 8.204
    (a)(1)(C).)
    20
    that Dr. Crow knew or reasonably suspected that Ryann’s foot injury on the morning of
    October 23d was the result of assault or abuse. (See Code Civ. Proc., § 437c, subd. (e);
    
    Horn, supra
    , 72 Cal.App.4th at p. 807.)
    The same is true of another version of the story in the declaration of Rochelle
    Bunnell, in which Ryann told her sister not to come to the house because Dr. Crow “was
    handling it.” Ms. Bunnell declared that she did go to the house where she observed
    Dr. Crow checking on Ryann’s ankle, at which time Dr. Crow “glared at Jessie, shaking
    his head side to side.”15 We would not have excluded the whole of what Ms. Bunnell
    stated she actually observed—namely that Dr. Crow was at the house around 8:00 a.m.
    the morning of October 23rd and that he glared at Jesse while examining Ryann’s foot.
    Even this evidence, and the inferences reasonably drawn from it, viewed in the light most
    favorable to Pipitone, at best establishes that witnesses had conflicting accounts of when
    Dr. Crow visited the house, and that Dr. Crow directed a negative expression toward his
    son.16
    Pipitone also offered the expert testimony of Dr. Linda Barnard. Pipitone cites
    Jambazian v. Borden (1994) 
    25 Cal. App. 4th 836
    for the proposition that where Dr. Crow
    failed to offer expert testimony that his conduct as a practitioner met the standard of care,
    the “uncontradicted declaration” of Dr. Barnard was sufficient to establish the standard of
    care and breach. This reliance on Jambazian is misplaced. In Jambazian, the court of
    appeal affirmed a summary judgment in favor of the treating physician because the
    15
    While Ms. Bunnell’s declaration describes Dr. Crow glaring and shaking his
    head at Jesse, there is no citation to the record—nor does the record reflect—Pipitone’s
    additional contention that Dr. Crow also said to Jesse “words to the effect of ‘what the
    fuck did you do?’ ” We accordingly disregard the latter, unsupported part of the
    statement in Pipitone’s papers.
    16
    Such negative expression would not be a surprise considering Dr. Crow knew
    that his son was intoxicated and driving the truck that ran over Ryann’s foot.
    21
    plaintiff did not offer opinion evidence to contradict the defendant’s expert declarations
    on the standard of care of the medical community. 
    (Jambazian, supra
    , at p. 844.)
    Here we do not have a medical malpractice negligence case in which “expert
    testimony is required to establish a health care practitioner’s failure to exercise the
    requisite degree of learning, care or skill so as to satisfy the necessary standard of care,”
    but one in which the alleged tort arises out of a statutory violation. (See Ewing v.
    Northridge Hosp. Medical Center (2004) 
    120 Cal. App. 4th 1289
    , 1302.) In the closely
    related context of a physician’s statutory duty to report child abuse, our Supreme Court
    has explained that “in the event a physician does diagnose a battered child syndrome, due
    care includes a duty to report that fact to the authorities . . . although expert testimony on
    the issue of a duty to report is admissible, it is not mandatory.” 
    (Landeros, supra
    , 
    17 Cal. 3d 399
    , 410, fn.8.) Similarly in 
    Ewing, supra
    , at page 1303, footnote 7, the court of
    appeal drew the same distinction, noting that to prove a violation of a physician’s
    statutory duty to report suspected cases of child abuse, a plaintiff must show “the doctor
    actually observed injuries and formed an opinion they were intentionally inflicted on the
    child. Expertise, while permissible, is not necessary.” We accordingly reject the
    contention that expert testimony was required.
    The predicate question here is whether, under the facts and circumstances put forth
    in opposition to summary judgment, it was “objectively reasonable” for Dr. Crow to
    entertain a suspicion of abuse. (Pen. Code, § 11162.5, subd. (d).) If not, then a duty to
    report never arose. Assuming for the sake of argument that Dr. Barnard’s qualifications
    were sufficient to render an opinion on this issue,17 she does not indicate on what, if any,
    17
    Evidence Code 720, subdivision (a) sets forth the standard by which we
    measure if a person is qualified to testify as an expert. We agree with Dr. Crow and Dr.
    Williams’ criticism of Dr. Barnard’s qualifications to the extent that the testimony is
    offered to prove the medical standard of care of a physician under the reporting statute, or
    seeks to render a legal opinion on the purpose of the mandatory reporting statute. We are
    not so quick to deem her qualifications insufficient to render an opinion, however, on the
    impacts of health care provider mandatory reporting of domestic abuse, or on the state of
    22
    substantiated facts she based her opinion that Dr. Crow “had or should have had
    reasonable suspicion.”
    An expert’s opinion “unaccompanied by a reasoned explanation connecting the
    factual predicates to the ultimate conclusion” lacks evidentiary value and may be deemed
    conclusory. (Jennings v. Palomar Pomerado Health Systems, Inc. (2003) 
    114 Cal. App. 4th 1108
    , 1117 (Jennings).) Viewing the evidence and all reasonably drawn
    inferences in the light most favorable to Pipitone (see Aguilar v. Atlantic Richfield 
    Co., supra
    , 25 Cal.4th at p. 843), Dr. Crow’s fractured awareness of past problems on the part
    of his son, taken in conjunction with his knowledge that his son was driving the truck
    when it ran over Ryann’s foot, that both Jesse and Ryann had been drinking at the time,
    and that her injuries were consistent with the stated mechanism of injury, do not create a
    reasonable suspicion of abuse any more than they might create a reasonable suspicion of
    reckless behavior on the part of the recently married couple. Without some reasoned
    explanation, the “indisputed” evidence that Dr. Barnard described does not add up to the
    opinion rendered. As such, it is purely conclusory. (See 
    Jennings, supra
    , 114
    Cal.App.4th at p. 1117.) We conclude that the trial court properly excluded Dr. Barnard’s
    opinion as to liability.
    Pipitone also argued that the $5,000 “payoff” scheme in which Dr. Crow gave
    Jesse $2,500 created a triable issue of fact that Dr. Crow knew that Ryann’s foot injury
    resulted from abuse. The accusation of abuse by Pipitone and demand for payment to
    Ryann took place several days after the brief window on October 23d in which Ryann
    mind of the doctors presented with Ryann’s injuries. Dr. Barnard’s training and
    experience as a marriage family therapist and counselor educator in the field of domestic
    violence may have imbued her with the “special knowledge, skill, experience, training, or
    education” in those specific areas. (See Mann v. Cracchiolo (1985) 
    38 Cal. 3d 1
    , 38 [the
    determinative issue is “whether the witness has sufficient skill or experience in the field
    so that his testimony would be likely to assist the jury in the search for the truth”].)
    However, because we find that Dr. Barnard’s opinions are inadmissible on other grounds,
    we need not examine her qualifications as a whole.
    23
    was under Dr. Crow’s care. We conclude that it could have had no bearing on whether
    Dr. Crow reasonably suspected abuse within the scope of the statutory scheme.18
    Because we find on the evidence presented that there is no triable issue of fact to
    indicate that at the time Dr. Crow treated Ryann, he should have known or reasonably
    suspected that her foot injury flowed from violence, Pipitone’s allegation that Dr. Crow
    breached his statutory duty must fail. That being true, Pipitone cannot establish a
    presumed failure to exercise due care under Evidence Code section 669, which among
    other elements requires violation of a statute.
    2. Dr. Williams’ Statutory Duty to Report Suspected Abuse
    Nor do we find any triable issues of material fact with regard to Dr. Williams’
    alleged duty to report known or suspected domestic violence. As discussed above,
    “[r]easonably suspects” is an objective standard “based upon facts that could cause a
    reasonable person in a like position, drawing, when appropriate, on his or her training and
    experience, to suspect.” (Pen. Code, § 11162.5, subd. (d).)
    In support of his motion on this point, Dr. Williams presented his declaration
    describing Ryann Bunnell’s visit to his office on October 23, 2009 for an examination
    and x-ray of her foot and related injuries, the deposition testimony of Pipitone, and
    Pipitone’s response to written discovery in which she admitted that “the patient’s [Ryann]
    injuries were entirely consistent with her report of having had her foot run over by a lifted
    truck.” With this combined evidence, Dr. Williams made a prima facie showing that he
    did not know or reasonably suspect abuse within the meaning of the statute.
    In opposition, Pipitone offered Dr. Williams’ deposition testimony evidencing his
    prior friendship with the Crow family and the fact that he knew Jesse Crow’s mother was
    18
    We read Penal Code sections 11160 and 11161 to require that the knowledge or
    suspicion of abuse be contemporaneous to the doctor’s provision of medical services for
    a patient while acting in the scope of employment as a health professional (under Pen.
    Code, § 11160), or while the injured person is under his or her charge or care (under Pen.
    Code, § 11161).
    24
    an x-ray technician. She also offered the declaration of Ryan McGuirk summarizing
    Dr. Williams’ statements in a recorded interview during the murder investigation.19
    According to McGuirk, Dr. Williams stated that he had known Jesse and Ryann before he
    saw her as a patient on October 23, 2009, and that “[h]e declined to say much of what he
    knew about Jessie, as it was difficult for him given his personal relationship with the
    Crows.” Pipitone also offered the expert declaration of Dr. Barnard. As with Dr. Crow,
    Dr. Barnard opined that Dr. Williams “had or should have had at least a reasonable
    suspicion” of abuse, providing as her rationale the descriptions of the incident provided
    by Ryann and Jesse to Dr. Williams “were inconsistent and lacking in detail” and that
    “Dr. Williams knew that Jessie [sic] mother provided x-ray services, and thought it was
    odd they did not go to his mother for those services. The [sic] is evidence that he was
    contacted by either Dr Crow or Mrs Crow prior to treatment.”
    Dr. Barnard’s opinion as to Dr. Williams’ state of mind lacks sufficient reasoned
    explanation to connect what appear to be immaterial facts to her conclusion. (See
    
    Jennings, supra
    , 
    114 Cal. App. 4th 1108
    , 1117.) Viewed in a light most favorable to
    Pipitone, the inconsistencies brought out by the remainder of the evidence are not
    material and provide no basis on which to draw a reasonable inference that Dr. Williams
    reasonably suspected abuse. Evidence that leads only to speculation or conjecture does
    not create a triable issue of fact. (See 
    Horn, supra
    , 72 Cal.App.4th at p. 807.)
    Accordingly, we conclude that there exists no triable issue of fact as to the duty
    element of the causes of action against Dr. Williams.
    3. Proximate Causation
    Our conclusions above are dispositive of the causes of action alleged against
    Dr. Crow and Dr. Williams. Yet if Pipitone could arguably raise a triable issue of
    19
    The record does not reflect that Dr. Williams raised any objections to the
    McGuirk Declaration.
    25
    material fact as to the duty element for either respondent, we find that she could not do so
    as to causation.20
    There are two aspects to proximate causation: cause in fact, sometimes referred to
    as but-for causation; and public policy considerations that are held to limit an actor’s
    liability for the consequences of his conduct. (State Dept. of State Hospitals v. Superior
    Court (2015) 
    61 Cal. 4th 339
    , 352-353, rehg. den. (July 22, 2015) (State Hospitals).) The
    first aspect is determinative here. “ ‘ “An act is a cause in fact if it is a necessary
    antecedent of an event.” ’ ” (Ibid., quoting Ferguson v. Lieff, Cabraser, Heimann &
    Bernstein (2003) 
    30 Cal. 4th 1037
    , 1045.) That is, a defendant whose conduct was a
    substantial factor in causing the plaintiff’s harm “cannot avoid responsibility just because
    some other person, condition, or event was also a substantial factor in causing the
    plaintiff’s harm; but conduct is not a substantial factor in causing harm if the same harm
    would have occurred without that conduct.” (Yanez v. Plummer (2013) 
    221 Cal. App. 4th 180
    , 187, rehg. den. (Nov. 26, 2013), review den. (Feb. 19, 2014).)
    Pipitone alleges that Ryann’s death, and the resulting losses that form the basis of
    the wrongful death action, were the proximate result of each physician’s failure to report
    known or suspected abuse. Dr. Crow and Dr. Williams separately argue that Pipitone has
    not and cannot adduce evidence upon which the trier of fact can reasonably find or infer
    causation. Though proximate cause is generally considered a question of fact for
    determination by a jury, “ ‘where the facts are such that the only reasonable conclusion is
    an absence of causation, the question is one of law, not of fact.’ ” (State 
    Hospitals, supra
    , 
    61 Cal. 4th 339
    , 353, quoting Weissich v. County of Marin (1990) 
    224 Cal. App. 3d 1069
    , 1084.) We find this to be one such occasion.
    20
    Pipitone’s theory of proximate causation is identical as to both respondents, as
    are the pertinent facts. Keeping in mind that Dr. Crow and Dr. Williams each raised
    separate arguments in their papers, we find it most efficient to address the issue of
    causation together.
    26
    In State Hospitals, the California Supreme Court considered on appeal from
    demurrer whether an alleged breach of mandatory duties under the Sexually Violent
    Predators Act (SVPA) by state actors, resulting in a prison inmate’s release, could be
    considered the proximate cause of the inmate having raped and murdered the plaintiff’s
    decedent just four days after he paroled. (State 
    Hospitals, supra
    , 61 Cal.4th at p. 343.)
    The plaintiff alleged that had the defendants complied with the procedure mandated by
    the SVPA to determine if the inmate was likely to be a sexually violent predator (SVP),
    that evaluation process would have resulted in a referral by the state agency for civil
    commitment, and ultimately civil commitment, not release. (Id., at p. 346-347.) The
    Court reviewed a line of cases in which proximate cause was not established as a matter
    of law by a defendant’s failure to act because the “chain of causation included
    discretionary determinations for which no liability could be imposed.” (Id., at p. 353.)
    One case cited in State Hospitals is Fleming v. State of California (1995) 
    34 Cal. App. 4th 1378
    (Fleming), in which a parolee committed murder and the victim’s family alleged
    that the parole officer had breached a mandatory duty to arrest the killer for a parole
    violation. The court of appeal affirmed the dismissal, noting in relevant part that the
    failure to arrest “was not itself a cause of the injury, since arrest without a period of
    incarceration would not necessarily have prevented the crime. Incarceration, however,
    would have involved procedural steps involving the exercise of discretion and thus have
    broken the causal chain.” 
    (Fleming, supra
    , 34 Cal.App.4th at p. 1384.)
    The Court in State Hospitals similarly concluded that the chain of intervening
    discretionary acts doomed the plaintiff’s proximate cause allegation regarding
    commitment of the SVP. (State 
    Hospitals, supra
    , 61 Cal.4th at p. 356 [“Plaintiff’s
    showing of ‘but for’ causation is weak, because with each step in the review process the
    results become more speculative.”].) Though decided at the pleading stage with regard to
    mandatory duties of government actors, the analysis in State Hospitals is instructive. In
    particular, the Court cautioned that the purpose of cause in fact is “to safeguard against
    27
    speculative and conjectural claims.” (State Hospitals, 
    61 Cal. 4th 339
    , 355.) Our analysis
    turns on the nature of the intervening acts that took place between the alleged breach of
    mandatory duty by Drs. Crow and Williams, and Ryann’s murder.
    In their motions, both respondents asserted evidence of an extended chain of
    causation that involved discretionary decisions by the police, as well as Ryann’s non-
    cooperation in the limited police investigation that did occur. This chain included the
    following facts. Ryann did not reveal her abuse to the health care providers whose care
    she sought for her foot injury. Despite the “agreement” to frame the truck incident as an
    accident, about two months later Pipitone reported the incident and other abuse to the
    police. Ryann’s sister, Rochelle Bunnell, made similar reports. In response, a Salinas
    police officer interviewed Pipitone and Ryann in person. Ryann told the officer that she
    feared Jesse and admitted that he had run over her foot with a truck, had guns and was
    involved with “lots of illegal things.” Ryann also told the officer that she did not want a
    report and felt it was best if she kept her mouth shut because she was afraid Jesse would
    come after her and her family. Ryann accepted a pamphlet from the officer that
    contained information and resources for victims of domestic violence. The officer ran a
    warrant check on Jesse and saw that he was on probation with the condition he “obey all
    laws.” The officer forwarded his report to two jurisdictions, the Monterey County
    Sheriff’s Department and Monterey Police Department, but neither he nor the other
    departments took any further action. Over a month later, and about four months after the
    alleged breaches of mandatory duty, Jesse murdered Ryann.
    Respondents argued that there was no evidence to suggest that had either
    Dr. Williams or Dr. Crow reported abuse, the outcome would have been any different. In
    her opposition, Pipitone did not dispute the facts outlined above but contended that there
    was sufficient evidence under the substantial factor test to send the issue to a jury for
    determination, including as to the foreseeability of Jesse’s deadly intervening act.
    Pipitone offered only the expert declaration of Dr. Barnard to create a triable issue of
    28
    fact. We find, however, that Dr. Barnard’s opinions on causation lack foundation, are
    unsupported by reasoned explanation, and are conclusory. These three opinions state:
    “9. [A] failure to report the information by these health care providers to law
    enforcement increased the risk of injury to Ryann Bunnell by way of assault and/or
    battery to an unusual degree . . . .
    “10. It is my further opinion that the murder of Ryann Bunnell is directly related
    to the failure to report the incident of on or about October 22, 2009.
    “11. It is my further opinion that compliance with Penal Code Sections 11160 and
    11161, would more likely than not have prevented the murder of Ryann Bunnell. Under
    the circumstances, the nature of the conduct committed in murdering Ryann Bunnell was
    not random nor unforeseeable; it was not the type of crime that would simply be
    displaced to another time or location under changed circumstances. Instead, with proper
    reporting, this crime would, more likely than not, not have occurred at all.”
    Dr. Barnard failed to indicate how she came to these profound conclusions. An
    expert’s opinion may not be based on assumptions of fact without evidentiary support, or
    on speculative or conjectural factors. (
    Jennings, supra
    , 
    114 Cal. App. 4th 1108
    , 1117.)
    The trial court properly excluded this inadmissible evidence.
    In support of her argument that a purported lack of proximate causation could not
    be decided as a matter of law, Pipitone also pointed to 
    Landeros, supra
    , 
    17 Cal. 3d 399
    .
    Landeros involved a doctor’s failure to diagnose battered child syndrome after treating
    injuries from egregious physical abuse on an 11-month-old infant by the infant’s mother
    and common law father. The medical team released the infant back to her parents, after
    which she suffered further injuries resulting in permanent damage. (Id., at pp. 405-407.)
    The California Supreme Court in Landeros explained that because battered child
    syndrome included among its “distinguishing characteristics” the likelihood “that the
    assault on the victim is not an isolated, atypical event but part of an environmental
    mosaic of repeated beatings and abuse,” the trial court “could not properly rule as a
    29
    matter of law that the defendants’ negligence was not the proximate cause of plaintiff’s
    injuries. Plaintiff is entitled to prove by expert testimony that defendants should
    reasonably have foreseen that her caretakers were likely to resume their physical
    abuse . . . if she were returned directly to their custody.” (Id., at p. 412.)
    Like in State Hospitals, Landeros involved a review of dismissal on a demurrer.
    The Court in State Hospitals distinguished Landeros and other similar cases because they
    did not involve “a series of discretionary determinations” that necessarily formed the
    basis of proximate causation. (State Hospitals, 
    61 Cal. 4th 339
    , 357, fn. 16.) We find that
    the undisputed facts of this case are more closely analogous to those alleged in State
    Hospitals. If the child abuse perceived in Landeros had been reported to the authorities, it
    would likely have had an immediate effect on whether the infant was returned to the
    custody of her potential abusers. Being that the victim was a young child, there was no
    conduct on her part that could have dissuaded an investigation by law enforcement. In
    contrast, Pipitone has put forth no evidence that had Dr. Crow and/or Dr. Williams
    reported suspected abuse, a resulting investigation would more likely than not have
    achieved a different or better outcome than the investigation that actually took place.
    And like in State Hospitals, the inquiry by law enforcement would have been only the
    first step in a necessary chain of discretionary decisions by the police or sheriff’s
    department, which would have had to culminate in the arrest and detention of Jesse. (See
    State Hospitals, 
    61 Cal. 4th 339
    , 357 [plaintiff’s showing of cause in fact was
    “conjectural, depending on a long series of determinations that would have been required
    after [defendant’s] breach in order for the injury to have been prevented”].)
    For these reasons, we conclude that there exists no triable issue of material fact as
    to the element of causation with respect to either Dr. Crow or Dr. Williams.
    30
    3. Equitable Estoppel Asserted by Dr. Williams
    Because we conclude that the trial court properly granted Dr. Williams’ motion for
    summary judgment on the grounds of duty and causation, we do not reach his third
    contended ground of estoppel.
    DISPOSITION
    The judgments in favor of Dr. Crow and Dr. Williams are affirmed. The parties
    shall bear their own costs on appeal.
