    No. 07–1999
    Filed January 8, 2010
    STATE OF IOWA,
    Appellee,
    vs.
    JUNE BETTY LYMAN,
    Appellant.
    Appeal from the Iowa District Court for Woodbury County,
    Duane E. Hoffmeyer, Judge.
    The defendant appeals her conviction for second-degree murder.
    AFFIRMED.
    Mark C. Smith, State Appellate Defender, and Martha J. Lucey,
    Assistant State Appellate Defender, for appellant.
    Thomas J. Miller, Attorney General, Jean C. Pettinger, Assistant
    Attorney General, Patrick Jennings, County Attorney, and Terry C.
    Ganzel, Assistant County Attorney, for appellee.

    WIGGINS, Justice.
    The defendant appeals from her conviction for second-degree
    murder alleging that the district court erred in holding she was
    competent to stand trial and by failing to instruct the jury that murder in
    the second degree is a specific intent crime. She also claims her trial
    counsel provided ineffective assistance of counsel by failing to redact
    and/or object to the introduction of evidence depicting the defendant’s
    repeated invocations of her right to remain silent as well as failing to
    object to prosecution references to these statements during closing
    arguments.     In this appeal, we find the district court correctly
    determined the defendant was competent to stand trial and that she was
    not entitled to a specific intent instruction.     We also find the record
    inadequate    to   decide    her   ineffective-assistance-of-counsel   claim.
    Accordingly, we affirm her conviction.
    I.     Background Facts and Proceedings.
    June Lyman dropped out of high school and married Bob Auen
    when she was fifteen years old. She had three daughters and one son
    during the course of the marriage. A court dissolved her marriage after
    seven or eight years.       In 1967 June married Leo Lyman, Sr.        Their
    relationship was rocky.       During the marriage, Leo allegedly sexually
    assaulted June’s three daughters from her first marriage. In May 1970
    Leo was charged with three counts of lascivious acts with a child but the
    case was later dismissed for lack of prosecution. The couple divorced in
    July 1979 but later remarried in November. The couple divorced for a
    second time in 1998; however, they remarried a third time sometime
    before 2006. In 2004, Sandra, one of June’s three daughters, committed
    suicide causing June to experience increased depression and anxiety.
    3
    At approximately 8:14 p.m. on May 15, 2006, June called her
    daughter-in-law and asked to speak to her son. He was not home, so
    she hung up.    Seven minutes later, an anonymous female called 911,
    gave an address, requested police assistance, and reported a dead body
    in the residence.   The phone used to make the call was listed under
    June’s name and the address provided was her residence. At 8:31 p.m.,
    June called her daughter-in-law and again asked to speak to her son. At
    8:33 p.m., June called her daughter-in-law for a third time, again asked
    to speak to her son, and then stated, “oh, God, I just shot Dad” and hung
    up.
    Deputy Todd Peterson arrived at June’s residence around the time
    June made the last call to her daughter-in-law.         Upon entering the
    residence, he noticed Leo lying on the floor on his right side, facing the
    door, with blood coming from his mouth. He also saw a revolver lying on
    the floor directly behind Leo. The police later identified the revolver as
    the murder weapon.     While Peterson was checking Leo’s vitals, June
    entered the room, stood over Leo, and told Peterson that he deserved
    what he got, he was a child molester, and she hoped he was dead. June
    further stated that he should have been dead a long time ago, she had
    shot him, and her fingerprints were all over the gun.
    A volunteer EMT, who was on the scene to administer first aid,
    confirmed Leo was dead. He had been shot four times, with the lethal
    shot striking him in the left lower chest. While working on Leo, the EMT
    heard June say, “yes, I did it.    I shot him.”   At the scene, Peterson
    observed that June spoke coherently, appeared to understand what was
    going on, and at one point even asked to make a phone call so that
    someone could take care of her dog.      Peterson smelled alcohol in the
    residence and on June’s breath. He noticed there were numerous beer
    4
    cans in the kitchen. He also thought June’s words were not slurred, but
    her balance was a little unsteady. June admitted to him that she was
    intoxicated.
    Peterson read June the Miranda warning at approximately
    8:37 p.m.      Peterson observed that June appeared to understand her
    rights when he read them to her. A short time thereafter, she requested
    an attorney.     Peterson allowed June to call her daughter-in-law before
    transporting her to the law enforcement center. During the transport,
    June voluntarily made numerous incriminating statements that were
    recorded by the patrol car’s video recording system, such as, “I shot the
    motherfucker,” “I’ve already admitted to you I killed him,” and “I shot the
    fucker.   Hey, and I can’t deny it.      My fingerprints are on the gun.”
    During the transport, June also repeatedly referenced her right to an
    attorney and her right to remain silent.
    Upon arriving at the law enforcement center, Deputy Todd Wieck
    walked June to an office. June appeared to act normal, seemed to know
    what was going on, did not slur her words, and did not appear
    intoxicated.    Wieck placed June in an office furnished with videotape
    equipment. Another deputy informed her that she was being recorded
    and reread the Miranda warning. After hearing the Miranda warning for
    a second time, June again stated, “I want an attorney.”        Due to her
    request, the officers did not question her.        However, rather than
    remaining silent, June continued to voluntarily make incriminating
    statements such as, “I shot the gun,” “I never thought it was that easy to
    die or I would have done it a long time ago,” and “[w]ell, it’s not self-
    defense actually. I wasn’t threatened, but I had a reasonable reason.” At
    the same time, June continued to request an attorney and state that she
    probably should not be saying anything.
    5
    While at the law enforcement center, investigators performed a
    blood-alcohol-content test on June. A deputy administered a breath test
    at approximately 12:32 a.m. to determine June’s blood-alcohol content.
    June admitted to drinking ten beers and stated she felt buzzed at the
    time the test was administered. The test’s final reading confirmed that
    June’s blood-alcohol content was 0.133.               Using a standard absorption
    rate, June’s blood-alcohol content was approximately 0.213 at the time
    she called 911.         Moreover, June also had prescriptions for the drugs
    Lipitor, Wellbutrin XL, Alprazolam, Naproxen, Daltiazem, Premarin, and
    Triamterene at the time of the shooting.
    The State charged June with murder in the first degree. June filed
    a motion requesting the district court determine whether she was
    competent to stand trial.           She claimed an inability to remember and
    recall facts surrounding the shooting, making her unable to assist her
    attorneys in preparing her defense and rendering her incompetent
    pursuant to Iowa Code section 812.3 (2005). 1
    After hearing testimony from experts on both sides, the district
    court concluded June had failed to carry her burden of proof to show her
    incompetence.           Therefore, the presumption of June’s competency
    prevailed. Accordingly, the court denied the motion and set the matter
    for trial.
    June then filed a motion for the adjudication of a law point,
    seeking a determination from the court regarding whether second-degree
    murder, under Iowa Code section 707.3, is a specific intent crime. The
    district court stated its preliminary observation and research indicated
    second-degree murder was not a specific intent crime.                    However, the
    1All   references to the Iowa Code are to the 2005 Code unless otherwise noted.
    6
    court deferred action on the motion to the time and place June made her
    record on the jury instructions.
    At trial, the State played the full video recordings of June’s
    transport to the law enforcement center as well as her later detention in
    an office located within the center. At no point during the presentation
    of this evidence did her attorneys object or ask to redact any portion of
    the videos.
    At the conclusion of the evidence, June renewed her argument that
    because assault, a specific intent crime, is a lesser-included offense of
    second-degree murder, the specific intent required for an assault must
    be proven to establish second-degree murder.      Therefore, June argued
    that to establish second-degree murder the State was required to prove
    beyond a reasonable doubt that she had the specific intent to commit an
    assault even though the State need not establish a specific intent to kill.
    The district court denied June’s motion and found that second-degree
    murder is a general intent crime.
    During the State’s closing argument, the prosecuting attorney
    referred three times to June’s invocation of her right to remain silent by
    requesting an attorney.      June’s counsel did not object to these
    references. The jury returned a unanimous verdict finding June guilty of
    the lesser-included offense of murder in the second degree.          June
    appeals.
    II. Issues.
    In this appeal, June raises three issues. First, we must determine
    whether the district court’s determination that June was competent to
    stand trial was correct. Next, we must decide whether the district court
    properly instructed the jury with regard to the elements of murder in the
    second degree. Finally, we must consider whether June’s trial counsel
    7
    was ineffective for failing to redact and/or object to the introduction of
    the video evidence depicting June’s repeated invocations of her right to
    remain silent by requesting an attorney and for failing to object to
    references concerning these invocations made in the prosecutor’s closing
    argument.
    III. Competence to Stand Trial.
    A. Standard of Review. June claims the standard of review is de
    novo. The State claims the standard of review is for correction of errors
    at law and that we are bound by the district court’s finding of
    competency, if it is supported by substantial evidence.    June and the
    State cite Iowa authority for their respective positions. Accordingly, to
    determine the proper standard of review, it is necessary to review the
    applicable cases and statutes pertaining to competency.
    The trial of an incompetent defendant in a criminal matter violates
    the defendant’s due process rights as guaranteed by the Fourteenth
    Amendment to the United States Constitution. Cooper v. Oklahoma, 
    517 U.S. 348
    , 354, 
    116 S. Ct. 1373
    , 1376, 
    134 L. Ed. 2d 498
    , 505–06 (1996).
    Therefore, whether a defendant is competent to stand trial implicates a
    constitutional right.   State v. Edwards, 
    507 N.W.2d 393
    , 395 (Iowa
    1993).
    Prior to January 1, 1978, a jury determined a defendant’s
    competency to stand trial. Iowa Code § 783.2 (1975); see also State v.
    Drosos, 
    253 Iowa 1152
    , 1156, 
    114 N.W.2d 526
    , 528 (1962) (recognizing it
    is well settled law in Iowa that a jury determines the mental competency
    of a defendant to stand trial). Because a jury made the determination of
    a defendant’s competency, we reviewed the jury’s finding for substantial
    evidence and did not conduct a de novo review. 
    Id. 8 Effective
    January 1, 1978, the legislature repealed section 783.2.
    1976 Iowa Acts ch. 1245, ch. 4, §§ 526, 529. In its place, the legislature
    enacted section 812.4. 1976 Iowa Acts ch. 1245, ch. 2, § 1204. Section
    812.4 required the court to make the determination of a defendant’s
    competency to stand trial. Iowa Code § 812.4 (Supp. 1977). Although
    the legislature has amended chapter 812 numerous times since 1978,
    the determination of a defendant’s competency to stand trial has
    remained with the court. See Iowa Code § 812.5 (stating the court shall
    receive all relevant evidence and make the determination of a defendant’s
    competency to stand trial).
    Since 1978, we have been somewhat inconsistent as to the
    standard of review we use to determine if a defendant is competent to
    stand trial.   In State v. Lyon, 
    293 N.W.2d 8
    , 10 (Iowa 1980), the
    defendant’s competency to stand trial became an issue during the trial.
    At that point, the court recessed the trial, personally questioned the
    defendant, and heard testimony from various experts regarding the
    defendant’s competency.       
    Lyon, 293 N.W.2d at 12
    .     Based on this
    testimony, the trial court found the defendant competent to stand trial.
    
    Id. There, we
    conducted a de novo review, considered all the defendant’s
    circumstances, and affirmed the trial court’s finding of competency. 
    Id. at 9,
    12–13.
    One year later, we were confronted with another case where a
    defendant’s competency to stand trial was at issue.     State v. Jackson,
    
    305 N.W.2d 420
    , 422 (Iowa 1981). There, the trial court held a pretrial
    competency hearing.     
    Id. In reviewing
    the competency ruling, we
    determined the standard of review was at law to determine whether
    substantial evidence supported the trial court’s determination of
    competency. 
    Id. at 425.
    In reaching this conclusion, we did not discuss
    9
    the constitutional implications of the competency issue, but instead
    relied on our pre-1978 decisions reviewing jury determinations of
    competency. 
    Id. In 1981,
    we were again confronted with a case involving a
    defendant’s mental competency to stand trial.      State v. Pedersen, 
    309 N.W.2d 490
    , 491 (Iowa 1981). In Pedersen, the trial court conducted a
    pretrial hearing to determine the defendant’s competency.       
    Id. at 492.
    After hearing testimony from conflicting experts, the trial court found the
    defendant competent to stand trial. 
    Id. During the
    trial, the defendant
    began to display odd behavior.      
    Id. at 492–95.
       The trial continued
    despite this behavior.    
    Id. Noting that
    the trial of an incompetent
    defendant deprives that defendant of due process of law, we conducted a
    de novo review of the entire record including the pretrial hearing, the
    defendant’s conduct during trial, and his conduct following trial. 
    Id. at 495–501.
    Two years later, we were again confronted with the issue of
    competency.    State v. Aswegan, 
    331 N.W.2d 93
    , 95 (Iowa 1983).          In
    Aswegan, two pretrial hearings were held to determine the defendant’s
    competency to stand trial. 
    Id. After the
    second hearing, the trial court
    found the defendant competent to stand trial. 
    Id. There, we
    held the
    defendant did not raise a due process challenge with respect to the
    pretrial competency hearing; therefore, our review was not de novo. 
    Id. This holding
    is inconsistent with the Supreme Court’s statement that,
    “ ‘[c]ompetence to stand trial is rudimentary, for upon it depends the
    main part of those rights deemed essential to a fair trial, including the
    right to effective assistance of counsel . . . .’ ” 
    Cooper, 517 U.S. at 354
    ,
    116 S. Ct. at 
    1376–77, 134 L. Ed. 2d at 506
    (quoting Riggins v. Nevada,
    
    504 U.S. 127
    , 139–40, 
    112 S. Ct. 1810
    , 1817, 
    118 L. Ed. 2d 479
    , 492
    10
    (1992) (Kennedy, J., concurring)).    We cannot see how the issue of a
    defendant’s competence to stand trial does not implicate a defendant’s
    due process rights.
    In 1985, we reviewed another case involving the competency issue.
    State v. Emerson, 
    375 N.W.2d 256
    , 260 (Iowa 1985), abrogated on other
    grounds by Horton v. California, 
    496 U.S. 128
    , 
    110 S. Ct. 2301
    , 
    110 L. Ed. 2d 112
    (1990). In Emerson, the trial court held a pretrial hearing
    and determined the defendant was competent to stand trial.         
    Id. On appeal,
    we held the standard of review was de novo because
    constitutional safeguards were implicated. 
    Id. at 261.
    In 1993, we decided State v. Edwards, 
    507 N.W.2d 393
    (Iowa
    1993). There, the defendant’s competency became an issue during trial
    due to his obstreperous behavior.     
    Edwards, 507 N.W.2d at 394
    .        We
    reviewed the defendant’s trial conduct de novo to determine if he was
    competent to stand trial because the issue of his incompetence raised a
    constitutional issue. 
    Id. at 395.
    Finally, in 1996, we decided State v. Rieflin, 
    558 N.W.2d 149
    (Iowa
    1996). There, after a pretrial hearing, the trial court found the defendant
    competent to stand trial.       
    Rieflin, 558 N.W.2d at 151
    .       On our
    discretionary review, we relied on Jackson and Aswegan in holding the
    scope of review was at law for substantial evidence because the court
    had held a pretrial competency hearing.     
    Id. at 151–52.
      We did note,
    however, if competency became an issue during trial, our review was de
    novo. 
    Id. The Rieflin
    court did not distinguish Emerson or discuss the
    constitutional implications of a competency-to-stand-trial challenge.
    We believe Jackson, Aswegan, and Rieflin were wrongly decided as
    to the standard of review required when this court reviews a defendant’s
    pretrial hearing to determine his or her competence to stand trial.
    11
    Jackson relied on our old cases, decided under a statute that allowed a
    jury to determine the defendant’s competence to stand trial.         
    Jackson, 305 N.W.2d at 425
    .       Aswegan and Rieflin failed to consider that a
    defendant’s competency to stand trial implicates a constitutional right.
    
    Rieflin, 558 N.W.2d at 151
    –52; 
    Aswegan, 331 N.W.2d at 95
    .            In Iowa,
    when an appeal involves a defendant’s constitutional rights, we review
    the appeal de novo. See, e.g., State v. Bruegger, 
    773 N.W.2d 862
    , 869
    (Iowa   2009)   (reviewing   sentence    under   the   Cruel   and   Unusual
    Punishment Clause); Formaro v. Polk County, 
    773 N.W.2d 834
    , 838 (Iowa
    2009) (reviewing claim that a statute violated the Ex Post Facto Clause);
    State v. Harper, 
    770 N.W.2d 316
    , 319 (Iowa 2009) (reviewing claim
    involving the Confrontation Clause); State v. Cromer, 
    765 N.W.2d 1
    , 6
    (Iowa 2009) (reviewing ineffective-assistance-of-counsel claim under the
    Sixth Amendment); State v. Kramer, 
    760 N.W.2d 190
    , 193–94 (Iowa
    2009) (reviewing application of the Double Jeopardy Clause under the
    Fifth Amendment); State v. Mitchell, 
    757 N.W.2d 431
    , 434 (Iowa 2008)
    (reviewing constitutionality of a statute under the Equal Protection
    Clause); State v. Willard, 
    756 N.W.2d 207
    , 211–12 (Iowa 2008) (reviewing
    prohibition against bills of attainder under the Federal and Iowa
    Constitutions); State v. Fremont, 
    749 N.W.2d 234
    , 236 (Iowa 2008)
    (reviewing validity of a search warrant under the Fourth Amendment);
    State v. Harris, 
    741 N.W.2d 1
    , 5 (Iowa 2007) (reviewing right against self-
    incrimination under the Fifth Amendment); State v. Wells, 
    738 N.W.2d 214
    , 218–19 (Iowa 2007) (reviewing breakdown of the attorney-client
    relationship under the Sixth Amendment); State v. Smitherman, 
    733 N.W.2d 341
    , 345 (Iowa 2007) (reviewing conflict of interest implicating
    the right to counsel under the Sixth Amendment).
    12
    We review de novo a district court decision implicating a
    defendant’s constitutional rights, even if the district court held a full
    hearing on the matter below. 
    Formaro, 773 N.W.2d at 838
    ; 
    Harper, 770 N.W.2d at 319
    ; 
    Willard, 756 N.W.2d at 211
    ; 
    Fremont, 749 N.W.2d at 236
    ;
    
    Harris, 741 N.W.2d at 4
    –5; 
    Smitherman, 733 N.W.2d at 344
    –45.             The
    distinction made in Rieflin, that our review is de novo if the district court
    did not conduct a competency hearing, but for substantial evidence if the
    district court held a competency hearing, is inconsistent with our
    jurisprudence regarding the standard of review when constitutional
    issues are implicated.    We see no reason to treat a defendant’s due
    process rights, implicated by a claim of competency to stand trial, any
    differently from our review of other constitutional issues. Accordingly,
    we review a trial court’s decision as to a defendant’s competency to stand
    trial de novo and overrule any of our prior cases holding otherwise.
    B. Legal Framework. At common law, the State could not try a
    criminal defendant if that person’s mental condition was such that he or
    she lacked the capacity to understand the nature and object of the
    proceedings, to consult with counsel, and to assist in preparing a
    defense. Drope v. Missouri, 
    420 U.S. 162
    , 171, 
    95 S. Ct. 896
    , 903, 
    43 L. Ed. 2d 103
    , 112–13 (1975). The Supreme Court has stated the test to
    determine if a criminal defendant is competent to stand trial is whether
    the person “ ‘has sufficient present ability to consult with [counsel] with
    a reasonable degree of rational understanding—and whether [the person]
    has a rational as well as factual understanding of the proceedings.’ ”
    Dusky v. United States, 
    362 U.S. 402
    , 402, 
    80 S. Ct. 788
    , 789, 
    4 L. Ed. 2d 824
    , 825 (1960) (per curiam). In Iowa, we define the test as
    whether “the defendant is suffering from a mental disorder which
    prevents the defendant from appreciating the charge, understanding the
    13
    proceedings, or assisting effectively in the defense.”              Iowa Code
    § 812.3(1); accord 
    Rieflin, 558 N.W.2d at 152
    ; 
    Edwards, 507 N.W.2d at 395
    ; 
    Lyon, 293 N.W.2d at 9
    . The common thread running through these
    tests is that a criminal defendant must be able to effectively assist
    counsel in his or her defense.
    We presume a defendant is competent to stand trial.            
    Pedersen, 309 N.W.2d at 496
    . The defendant has the burden of proving his or her
    incompetency to stand trial by a preponderance of the evidence. 
    Id. If the
    evidence is in equipoise, the presumption of competency prevails. 
    Id. Moreover, once
    a court finds a defendant competent to stand trial, the
    presumption of competency continues unless and until the defendant
    produces new evidence to the contrary. 
    Jackson, 305 N.W.2d at 425
    –26.
    In this appeal, June argues she suffers from amnesia concerning
    the facts and events surrounding the shooting; therefore, she asserts she
    was incompetent to stand trial because she was unable to effectively
    assist in her own defense. Particularly, she claims she was unable to
    assist her counsel in determining whether the defense of self-defense
    would be available to her.
    Amnesia on its own will not render a criminal defendant
    incompetent to stand trial.      
    Emerson, 375 N.W.2d at 261
    .         Rather, a
    court must determine whether an amnesic defendant is competent to
    stand trial by the circumstances of each individual case. United States v.
    Swanson, 
    572 F.2d 523
    , 526 (5th Cir. 1978). A subjective circumstance
    to consider is the defendant’s present ability to assist counsel in his or
    her defense.   
    Id. Under a
    subjective circumstance analysis, the court
    should   consider    the     defendant’s   particular   situation    including:
    (1) whether the defendant has the present ability to take the stand on
    matters other than the amnesic event, (2) whether the defendant suffers
    14
    from other pathological or psychological conditions that hinder the
    defendant’s present ability to assist in his or her defense, and (3) whether
    a continuance would remediate the situation. 
    Id. at 526–27.
    An objective circumstance to consider is whether the defendant
    can receive a fair trial despite his or her amnesia. 
    Id. at 527.
    To analyze
    this factor, a court should consider: (1) whether the crime and the
    defendant’s whereabouts could be reconstructed without the defendant’s
    testimony, (2) whether access to the information contained in the State’s
    files would help fill in the gaps of the defendant’s memory, and (3) how
    the defendant’s testimony would affect the strength of the State’s case.
    
    Id. C. Analysis.
    The experts testifying regarding June’s competency
    to stand trial offered differing opinions as to the extent and permanency
    of June’s amnesia.     On our de novo review, we find her amnesia is
    probably due to patchy memory retrieval, rather than memory formation.
    We reach this conclusion because she is able to remember some of the
    events, but not all of them.     Although we cannot say whether June’s
    amnesia is permanent or transient, we do believe it will probably last
    indefinitely into the future.   From a subjective standpoint, we are left
    with an individual who has a memory of the events, but for some reason
    cannot relate her entire memory of the events to her attorneys at this
    time.    We do not believe a continuance will help her patchy memory
    retrieval.
    June’s situation is not unlike many persons who are involved in
    similar incidents. No person’s memory is complete; even under the best
    conditions everyone is amnesic to some degree due to the natural loss of
    memory or the failure to observe. State v. Martens, 
    521 N.W.2d 768
    , 771
    (Iowa Ct. App. 1994); see also United States v. Stevens, 
    461 F.2d 317
    ,
    15
    320 (7th Cir. 1972); State v. McClendon, 
    437 P.2d 421
    , 423, 425 (Ariz.
    1968) (finding that “a defendant is entitled to a fair trial, but not
    necessarily to a perfect trial”). As the Seventh Circuit Court of Appeals
    noted about the plight of an amnesiac:
    “In his plight the amnesiac differs very little from an
    accused who was home alone, asleep in bed, at the time of
    the crime or from a defendant whose only witnesses die or
    disappear before trial. Furthermore, courts, of necessity,
    must decide guilt or innocence on the basis of available facts
    even where those facts are known to be incomplete, and the
    amnesiac’s loss of memory differs only in degree from that
    experienced by every defendant, witness, attorney, judge,
    and venireman. How much worse off is a generally amnesic
    defendant on trial for murder, for example, than one who
    remembers all but the dispositive fact: who struck the first
    blow?
    ....
    If a defendant is permanently amnesic, furthermore,
    there will be no time in the future when the court can secure
    the benefit of his version of the facts. The choice facing the
    court would therefore be that of proceeding to adjudicate the
    defendant’s guilt or innocence on the basis of incomplete
    data or abandoning the adjudicatory process altogether.”
    
    Stevens, 461 F.2d at 320
    (quoting Note, Amnesia: A Case Study in the
    Limits of Particular Justice, 71 Yale L.J. 109, 128–29 (1961)).
    In spite of June’s memory problems, we believe June can receive a
    fair trial. The State’s files and physical evidence make it relatively simple
    for the defense to reconstruct the facts surrounding the shooting. June
    was the only other individual at the house at the time of the shooting.
    The crime scene did not indicate a struggle took place prior to the
    shooting. June had no visible injuries indicating that Leo attacked her
    prior to the shooting. After the shooting, June made numerous calls to
    her family.   There was no indication from the manner in which she
    spoke, or in the words she used to describe the incident, that signaled
    16
    she was in imminent danger of death or injury at the time of the
    shooting.
    In none of the statements she made after the shooting, either at
    the scene, while being transported to the law enforcement center, or at
    the center, did she ever indicate that she shot Leo in self-defense. In
    fact, in two of her statements she said, “[w]ell, it’s not self-defense
    actually,” and “I wasn’t threatened, but I had a reasonable reason.”
    From the statements made by June, the physical evidence gathered, and
    the information contained in the State’s file, we conclude June’s amnesia
    did not prevent her from receiving a fair trial and agree with the district
    court that she was competent to stand trial.
    IV. Jury Instruction Regarding Second-Degree Murder.
    A. Standard of Review. June claims the district court erred by
    failing to give a specific intent instruction in connection with its
    instruction regarding second-degree murder. Although we review a claim
    that the court gave an improper jury instruction for correction of errors
    at law, we review the related claim that the trial court should have given
    a defendant’s requested instruction for abuse of discretion. Summy v.
    City of Des Moines, 
    708 N.W.2d 333
    , 340 (Iowa 2006). “Under Iowa law,
    a court is required to give a requested instruction when it states a correct
    rule of law having application to the facts of the case and when the
    concept is not otherwise embodied in other instructions.”         Herbst v.
    State, 
    616 N.W.2d 582
    , 585 (Iowa 2000) (emphasis added).
    B.    Analysis.   The court instructed the jury that before it could
    find June committed the crime of second-degree murder, the State had to
    prove the following elements:
    1. On or about the 15th day of May 2006, the
    defendant shot Leo Lyman.
    17
    2. Leo Lyman died as a result of being shot.
    3. The defendant acted with malice aforethought.
    June requested a specific intent instruction arguing that the act of
    shooting someone, as instructed in element number one, is an assault
    and to commit an assault, a person must necessarily have acted with
    specific intent. The district court rejected this argument and so do we.
    In Iowa, all crimes are statutory. Iowa Code § 701.2 (stating, “[a]
    public offense is that which is prohibited by statute and is punishable by
    fine or imprisonment”). Iowa Code section 707.1 provides that a person
    commits murder when that person “kills another person with malice
    aforethought either express or implied.” 
    Id. § 707.1.
    Murder in the first
    degree occurs when a person commits murder under any of the following
    circumstances:
    1. The person willfully, deliberately,          and   with
    premeditation kills another person.
    2. The person kills another person while participating
    in a forcible felony.
    3. The person kills another person while escaping or
    attempting to escape from lawful custody.
    4. The person intentionally kills a peace officer,
    correctional officer, public employee, or hostage while the
    person is imprisoned in a correctional institution under the
    jurisdiction of the Iowa department of corrections, or in a
    city or county jail.
    5. The person kills a child while committing child
    endangerment under section 726.6, subsection 1, paragraph
    “b”, or while committing assault under section 708.1 upon
    the child, and the death occurs under circumstances
    manifesting an extreme indifference to human life.
    6. The person kills another person while participating
    in an act of terrorism as defined in section 708A.1.
    18
    
    Id. § 707.2.
    Murder in the second degree occurs when “[a] person . . .
    commits murder which is not murder in the first degree.” 
    Id. § 707.3.
    Thus, murder in the second degree has only two elements—a person kills
    another person and does so with malice aforethought.
    The first element required for a person to commit second-degree
    murder is the killing of a person. The killing can occur by an affirmative
    act, such as when a person shoots another person, or by an omission to
    act when there is a duty to do so, such as when a parent fails to provide
    medical care for a child who dies from a lack of care.         1 Wayne R.
    LaFave, Substantive Criminal Law §§ 6.1, .2, at 422–23, 435–36 (2d ed.
    2003).
    The second element required for a person to commit second-degree
    murder is that the act of killing another person is done with malice
    aforethought.   Malice aforethought requires the actor to have “a fixed
    purpose or design to do physical harm to another that exists before the
    act is committed.” State v. Myers, 
    653 N.W.2d 574
    , 579 (Iowa 2002). “‘It
    does not mean mere spite, hatred, or ill will, but does signify that state of
    disposition which shows a heart regardless of human life.’ ”        State v.
    Leedom, 
    247 Iowa 911
    , 917, 
    76 N.W.2d 773
    , 777 (1956) (quoting State v.
    Burris, 
    198 Iowa 1156
    , 1158, 
    198 N.W. 82
    , 84 (1924), overruled on other
    grounds by State v. Kernes, 
    262 N.W.2d 602
    , 604 (Iowa 1978)). It is well-
    settled law that murder in the second degree is a general intent crime
    only requiring proof of malice aforethought. State v. Kraus, 
    397 N.W.2d 671
    , 672–73 (Iowa 1986).
    June argues when the court instructs the jury that the State must
    prove June shot Leo, the court must also give the jury a specific intent
    instruction because a shooting is an assault, and an assault can only be
    committed with specific intent. We disagree.
    19
    The first element the State must prove to convict June of second-
    degree murder is that June killed another person, namely Leo. It does
    not matter how she accomplished the act of killing. She could have shot
    Leo as alleged or withheld medical care if the State proved she had a
    duty to provide such care.     The manner of killing another is not an
    element of the crime; the only element required by the Code is that she
    did an act that killed another person. Thus, if the State proves June did
    an act to kill Leo with malice aforethought, she is guilty of murder in the
    second degree.     Neither the killing of another person nor malice
    aforethought requires specific intent under section 707.3. Consequently,
    the district court was correct in refusing to give a specific intent
    instruction for second-degree murder.
    V. Ineffective Assistance of Counsel.
    A. Standard of Review. Claims involving ineffective assistance of
    counsel have their basis in the Sixth Amendment to the United States
    Constitution and we review these claims de novo.       State v. Allen, 
    708 N.W.2d 361
    , 365 (Iowa 2006).
    B. Analysis. “ ‘In order for a defendant to succeed on a claim of
    ineffective assistance of counsel, the defendant must prove: (1) counsel
    failed to perform an essential duty and (2) prejudice resulted.’ ”      
    Id. (quoting State
    v. Wills, 
    696 N.W.2d 20
    , 22 (Iowa 2005)); see also
    Strickland v. Washington, 
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    , 2064, 
    80 L. Ed. 2d 674
    , 693 (1984).      To prove counsel failed to perform an
    “essential duty,” a defendant must prove counsel’s performance was
    deficient, meaning trial counsel “made errors so serious that counsel was
    not functioning as the ‘counsel’ guaranteed the defendant by the Sixth
    Amendment.”      
    Strickland, 466 U.S. at 687
    , 104 S. Ct. at 
    2064, 80 L. Ed. 2d at 693
    . Trial counsel’s performance is measured objectively by
    20
    determining   whether    counsel’s   assistance   was   reasonable,   under
    prevailing professional norms, considering all the circumstances. 
    Id. at 688,
    104 S. Ct. at 
    2065, 80 L. Ed. 2d at 694
    ; State v. Maxwell, 
    743 N.W.2d 185
    , 195 (Iowa 2008). Establishing this first prong is not easy
    because “ ‘there is a strong presumption trial counsel’s conduct fell
    within the wide range of reasonable professional assistance.’ ” State v.
    Graves, 
    668 N.W.2d 860
    , 881 (Iowa 2003) (quoting DeVoss v. State, 
    648 N.W.2d 56
    , 64 (Iowa 2002)).
    To establish prejudice, a defendant must prove “a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.” 
    Strickland, 466 U.S. at 694
    , 104
    S. Ct. at 
    2068, 80 L. Ed. 2d at 698
    . To establish a reasonable probability
    that the result would have been different, we have stated that a
    defendant “need only show that the probability of a different result is
    ‘sufficient to undermine confidence in the outcome.’ ”        
    Graves, 668 N.W.2d at 882
    (quoting 
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 
    2068, 80 L. Ed. 2d at 698
    ).
    June claims her trial counsel was ineffective for failing to redact
    and/or object to the introduction of video evidence depicting June’s
    repeated invocations of her right to remain silent by requesting an
    attorney, as well as for failing to object to several prosecution references
    to these statements made during the prosecutor’s closing argument. It is
    impermissible to use an individual’s exercise of his or her constitutional
    rights against them after the State implicitly assured the individual,
    through the Miranda warning, that his or her invocation of those rights
    would not be penalized.    Wainwright v. Greenfield, 
    474 U.S. 284
    , 292,
    
    106 S. Ct. 634
    , 639, 
    88 L. Ed. 2d 623
    , 631 (1986). Any breach of this
    implied assurance is a breach of fundamental fairness required by the
    21
    due process clauses of the Federal and Iowa Constitutions. 
    Id. at 291,
    106 S. Ct. at 
    638–39, 88 L. Ed. 2d at 630
    ; State v. Decker, 
    744 N.W.2d 346
    , 353–54 (Iowa 2008). Additionally, the Supreme Court has held that
    prosecutorial     comments        concerning   a    defendant’s   silence     are
    constitutionally banned.      Griffin v. California, 
    380 U.S. 609
    , 615, 
    85 S. Ct. 1229
    , 1233, 
    14 L. Ed. 2d 106
    , 110 (1965).           Under this record,
    however, we cannot reach June’s claim of ineffective assistance of
    counsel.
    The State charged June with first-degree murder.             First-degree
    murder is a specific intent crime. State v. Jespersen, 
    360 N.W.2d 804
    ,
    807 (Iowa 1985). As a defense to this charge, June raised the defense of
    diminished      responsibility.     The   court    instructed   the    jury   that
    “ ‘diminished responsibility’ means a mental condition which does not
    allow the person to form a premeditated, deliberate, specific intent to
    kill.”   The jury did not return a verdict for first-degree murder under
    these instructions. The state of the record does not allow us to decide if
    June’s trial counsel purposely decided not to object to this evidence or
    prosecutorial comments to show June’s mental state at the time of the
    shooting, in order to bolster her diminished responsibility defense. Trial
    tactics may require counsel to forego certain defenses or objections in
    pursuit of the best interests of the accused. State v. Rand, 
    268 N.W.2d 642
    , 649 (Iowa 1978).             Accordingly, we will not address June’s
    ineffective-assistance-of-counsel claim on direct appeal.
    VI. Disposition.
    We affirm June’s conviction for second-degree murder because the
    district court was correct when it found June competent to stand trial
    and when it refused to give a specific intent instruction for second-degree
    22
    murder. However, we do not reach June’s claim of ineffective assistance
    of counsel on direct appeal.
    AFFIRMED.
