    ZINTER, Justice
    [¶1.]         Jamie Corean was convicted of accessory to murder and aiding and
    abetting aggravated kidnapping. After the conviction but before we considered her
    appeal, the principal in the murder and kidnapping provided testimony claiming
    that Corean had no knowledge of or involvement in the offenses. As a result of the
    new evidence, we remanded the matter to the circuit court for supplementation of
    the record, further discovery, and consideration of a motion for new trial. Following
    an evidentiary hearing, the circuit court denied relief. The court found that the new
    evidence would not have produced an acquittal or changed the outcome of the trial
    because the principal’s testimony was irrelevant, biased, not reasonable, and lacked
    credibility. Corean now appeals the denial of her renewed motion for new trial and
    motion for judgment of acquittal. She also argues that the circuit court erred in:
    admitting co-conspirator statements; instructing the jury; finding that there was
    sufficient evidence to support the convictions; and, in imposing a mandatory life
    sentence. We affirm.
    Facts and Procedural History
    [¶2.]         On Monday, July 12, 2004, Troy Klug and Robert Highley went to
    Cynthia Kindall’s home in Rapid City to acquire methamphetamine. Duana Beebe,
    Klug’s girlfriend, testified that Klug wanted “to get [the] drugs as a front” 1 so he
    could repay a drug debt to Kindall. Kindall was also Beebe’s drug supplier. The
    1.      Beebe testified that a front is “when someone will give [another person] drugs
    without a money transaction and then they repay [the person who gave them
    the drugs] after they make money off of the drugs.”
    -1-
    #25001
    record reflects that Tory Tiegen was present, he had been residing in Kindall’s
    house, and Klug’s proposed drug purchase was part of an ongoing course of illegal
    drug trafficking at this house involving both Tiegen and Kindall.
    [¶3.]        When Highley and Klug arrived, they met Kindall and Tiegen.
    Highley was asked to leave, and he left in Klug’s vehicle. Kindall left shortly
    thereafter. When Kindall returned she observed that Klug was alive, but Tiegen
    had bound Klug with duct tape. Kindall and Tiegen loaded Klug into the trunk of
    Kindall’s car (a black Nissan) and left.
    [¶4.]        Tiegen and Kindall arrived at Beebe’s house that Monday evening
    around 9:00 p.m. Beebe asked Kindall where Klug was, and Kindall responded that
    she had kicked Klug out of her house. Beebe asked Kindall and Tiegen to leave.
    [¶5.]        James Kusick testified that Tiegen arrived at Kusick and Corean’s
    house (“Corean’s house”) in Belle Fourche on Tuesday morning, July 13, between
    6:00 and 7:00 a.m. Tiegen drove Kindall’s car into the garage, and once inside,
    Tiegen opened the trunk. Klug was in the trunk and was bound with duct tape.
    According to Kusick, Klug “couldn’t see, his arms were duct taped, his legs were
    duct taped.” Tiegen pulled Klug out of the trunk and “threw him on the floor.”
    Tiegen indicated that Klug was “a rat, a snitch.” Tiegen then kicked Klug in the
    stomach, and Kusick “heard [Klug] moan.” When Kusick went back inside the
    house, he told Corean that Tiegen “had somebody with him.” Corean did not
    suggest that they should intervene.
    [¶6.]        Tiegen testified that he put Klug in a tool box in the garage at Corean’s
    house that morning. Kusick testified that he “wanted nothing to do with” the
    -2-
    #25001
    situation, and he left for work. Corean indicated in prior testimony from Tiegen’s
    trial that after she went to work, she returned to see if Tiegen was gone. 2 When
    she saw that Tiegen was gone, she locked the garage.
    [¶7.]         On the way home from work that afternoon, Kusick told Eric Haar that
    Tiegen had left Klug at Corean’s house. Kusick asked Haar to check the tool box in
    the garage. Kusick testified that Haar opened the tool box, and Kusick “was
    standing by the door and [he] could see somebody in it.” Kusick testified that when
    Corean arrived home after work that afternoon, “I remember us telling her that
    [Tiegen] left this guy here and he’s still here.” According to Kusick, Corean did not
    suggest that someone should check on Klug’s well-being.
    [¶8.]         Abby DeJong, Corean’s best friend, testified that she arrived at
    Corean’s house on Tuesday, July 13, around 6:30 p.m. Corean told DeJong that
    Tiegen had put a person in a box in her garage. DeJong testified that Corean also
    told her that the person was being “held against [his] will.” When DeJong told
    Corean, “I think we need to do something,” Corean responded: “No, the cops will get
    them.” When DeJong attempted to convince Corean to call the police, Corean told
    her: “No, you’re not going to.” When DeJong told Corean that if DeJong were in the
    tool box, she “would want someone to help me,” Corean again replied: “No, the cops
    will get them.”
    [¶9.]         Tiegen and Kindall returned to Corean’s house late Tuesday evening.
    DeJong testified that when Tiegen and Kindall arrived, they had drugs with them
    2.      The State introduced Corean’s prior testimony.
    -3-
    #25001
    and everyone – Tiegen, Kindall, Haar, DeJong, and Corean – began using
    methamphetamine. According to DeJong, she asked Tiegen in Corean’s presence
    why Tiegen was keeping Klug in the tool box. DeJong testified that Kindall spoke
    up and stated “that Klug had owed them money.” Tiegen and Kusick went for a
    ride later that evening, and when they returned to Corean’s house, Corean, DeJong,
    Haar, and Kindall were still together in the living room using drugs. Before going
    to bed that evening, Kusick saw Tiegen and Corean talking together in the kitchen.
    [¶10.]         Tell Cook also lived in Belle Fourche. He testified that Tiegen and
    Kindall arrived at his house around 2:00 a.m. on Wednesday morning, July 14. 3
    3.       The exact day when Tiegen first arrived at Cook’s house – Tuesday or
    Wednesday – was disputed. At Corean’s post-trial hearing, Tiegen testified
    that he and Kindall went to Cook’s house on Tuesday morning, between 2:00
    and 4:00 a.m. Once there, Tiegen testified that he “used some meth.”
    According to Tiegen, he and Cook then drove Klug to a gravel road, “and
    scared him some.” Tiegen testified that Cook “punched [Klug], kicked him,
    hollered at him some.” Tiegen and Cook then put Klug back in the trunk of
    the car and returned to Cook’s house. According to Tiegen, he and Kindall
    then went to Corean’s house later Tuesday morning, “some[time] between
    6:00 and 7:00.”
    At Corean’s trial, Kindall also testified that she and Tiegen went to Cook’s
    house on Tuesday morning, before going to Corean’s house. Kindall conceded,
    however, that because she had been using drugs, she was not “certain of the
    days and dates during the time period,” that she did not “remember the dates
    very well,” and that she did not “remember Monday night; I don’t remember
    the dates[.]”
    Cook’s testimony at Corean’s trial was, however, unequivocal that Tiegen and
    Kindall arrived at his house on Wednesday morning, not Tuesday. Cook
    testified four different times that Tiegen first arrived early Wednesday
    morning. Cook was asked, “Is there anything you can think of or is there any
    reference that you have as to why it was early Wednesday morning?” Cook
    replied, “Because I was going on vacation, I had Friday off work and so that’s
    a good reference point to this whole thing. I had plans to go to Denver to a
    race track and it was just two nights before that.” Further, according to
    (continued . . .)
    -4-
    #25001
    According to Cook, Tiegen took Cook outside to Kindall’s vehicle and showed Cook
    that Klug was in the trunk. Klug’s hands, feet, and head were bound with duct
    tape, and he was lying face down in the trunk. Cook testified that Klug was still
    alive because he heard Klug moan and saw him reflex when Tiegen punched him in
    the back. Tiegen told Cook that he was either going to drive to Denver to turn Klug
    into Klug’s parole agent, or he was going to drive to North Dakota and dig a hole to
    bury Klug.
    [¶11.]         Tiegen and Kindall returned to Corean’s house around 5:30 a.m.
    Wednesday morning. Kusick testified that later that morning Tiegen told Kusick
    that Tiegen had “woke [Klug] up” and that Tiegen was leaving. Haar testified that
    he “remember[ed] asking [Kusick later], you know, what happened, was [Klug] okay
    or what’s up and [Kusick] said that [Tiegen] told him that it took a while to get
    ________________________
    (. . . continued)
    Cook, he and Tiegen never drove Klug to a gravel road, and Cook never
    struck Klug. Rather, Cook testified that after Tiegen showed Cook that Klug
    was in the trunk of the car, Cook allowed Tiegen and Kindall to stay at his
    house. When Cook left for work on Wednesday morning around 5:00 a.m.,
    Tiegen and Kindall were still there.
    The jury was required to resolve this factual dispute. From Cook’s testimony,
    the jury could have found that Klug was still alive Wednesday morning.
    Even if Tiegen and Kindall were at Cook’s house sometime Tuesday morning,
    there is no dispute that Tiegen went to Corean’s house on Tuesday morning,
    and there is substantial evidence that Corean acquired knowledge on
    Tuesday that Klug was alive and being held against his will in the tool box in
    her garage.
    -5-
    #25001
    [Klug] up, but he got him up.”4 Before Tiegen left, he instructed Kusick to “wash
    the [tool] box out.” Kusick washed the tool box at a car wash but there was
    “absolutely nothing” inside the tool box to wash. According to Kusick, “It had
    already been cleaned.”
    [¶12.]         On Wednesday evening, Kusick and Corean were at their house with
    DeJong and Haar. According to Kusick, he “wanted to tell the cops,” but “[w]e had a
    conversation that none of us would ever talk about it, we’d never say anything.”
    Kusick also remembered “hearing [Corean] say we need an alibi.” DeJong testified
    that when she talked to Corean on Wednesday, Corean informed DeJong that
    Tiegen was concerned about whether he could trust DeJong. According to DeJong,
    Corean reassured Tiegen not to worry about DeJong, and that Corean would “take
    care of it.”
    [¶13.]         Tiegen returned to Cook’s house the following morning, Thursday, July
    15. Tiegen told Cook that Tiegen had put Klug in the tool box, and that Tiegen had
    left Klug there all day. When Cook asked Tiegen if he had given Klug any water,
    Tiegen replied: “No, I didn’t give him any water, too late for that anyway.” Cook
    testified that Tiegen boasted that he went to the tool box several times during the
    day just to beat Klug. He told Cook that he felt the bones crush in Klug’s face and
    “that’s what probably did him in[.]”
    [¶14.]         Kindall and Tiegen left Belle Fourche for Montana on Thursday, July
    15. Kindall indicated that at that time, Klug was dead and still in the trunk of her
    4.       Haar indicated that he was not sure when this conversation occurred, but
    that it was either Tuesday night or Wednesday.

    car. Once in Montana, they drove into a canyon where Tiegen buried Klug by a
    fallen tree.
    [¶15.]         Tiegen was convicted of Klug’s kidnapping, and on January 16, 2008,
    this Court affirmed the conviction in State v. Tiegen, 
    2008 S.D. 6
    , 
    744 N.W.2d 578
    .
    On November 18, 2008, Tiegen was indicted for the first-degree murder of Klug.
    Following plea negotiations, Tiegen pleaded guilty to first-degree murder. Before
    his guilty plea, he had been subpoenaed to testify at Corean’s trial, but he exercised
    his Fifth Amendment right to remain silent. Corean was subsequently convicted of
    accessory to murder in violation of SDCL 22-3-5 and aiding and abetting aggravated
    kidnapping in violation of SDCL §§ 22-19-1(2) and 22-3-3. Following Corean’s
    conviction and appeal to this Court, she moved for a judgment of acquittal or new
    trial based on newly obtained testimony Tiegen would then provide following his
    plea. We remanded the matter for the circuit court’s consideration.
    [¶16.]          The circuit court conducted a hearing in which Tiegen testified.
    Tiegen claimed that Corean “never indicated” knowledge of the kidnapping. Tiegen
    also suggested that Klug was dead by the time Corean learned about Klug. Tiegen’s
    credibility was, however, attacked by showing bias in favor of Corean. 5 Tiegen
    5.       Tiegen testified:
    Q: Jamie Corean has been the only one that has never given
    evidence against you, hasn’t she?
    A: I guess I can’t really say that, I mean there’s [sic] people in
    the courtroom that have evidence against me.
    ***
    Q: One of the conditions of your plea agreement with the State
    was that we make an offer to Jamie Corean, correct?
    A: That was in this plea agreement, correct.
    (continued . . .)
    -7-
    #25001
    further acknowledged that Corean was home when Tiegen showed Kusick that Klug
    was in the trunk of the car. Tiegen finally acknowledged that he did not know if
    Corean went inside the garage at any time on Tuesday.
    [¶17.]       At the conclusion of the hearing, the circuit court denied Corean’s
    motions for judgment of acquittal and new trial. The court found that Tiegen’s
    testimony was biased and lacked credibility, and that it was merely cumulative and
    impeaching. The court ultimately found that Tiegen’s evidence was insufficient to
    have produced an acquittal or changed the outcome of the trial.
    I. Whether Tiegen’s post-trial testimony requires a new trial.
    [¶18.]       Corean argues that the circuit court erred in denying a new trial
    because Tiegen’s testimony was “highly reliable” and it “undermined confidence in
    the outcome of her trial.” “To succeed on a motion for a new trial based on after-
    discovered evidence, a defendant must prove that ‘(1) the evidence was undiscovered
    by the movant at the time of trial; (2) the evidence is material, not merely
    cumulative or impeaching; (3) that it would probably produce an acquittal; and (4)
    that no lack of diligence caused the movant to fail to discover the evidence earlier.’”

    should be granted is left to the sound discretion of the trial court, and this Court
    will not disturb the trial court’s decision absent a clear showing of abuse of
    discretion.” Id. ¶ 12, 
    600 N.W.2d at 539
    .
    [¶19.]        There is no dispute that Tiegen’s testimony was not available and was
    undiscoverable by Corean at the time of trial. The circuit court, however, denied a
    new trial on requirements (2) and (3), finding that Tiegen’s testimony was merely
    cumulative and impeaching, and that the evidence was insufficient to probably have
    produced an acquittal. We agree with the circuit court. Corean does not dispute the
    following findings indicating that Tiegen’s testimony was merely cumulative and
    impeaching:
       Tiegen confirmed that he first went to the Corean
    residence on the morning of July 13, 2004. This fact was
    confirmed by Kusick and the testimony of DCI agent Brent
    Gromer who testified that Corean admitted that this had
    occurred.
       Tiegen confirmed the testimony of James Kusick that
    Tiegen had displayed Troy Klug to Kusick in Corean’s
    garage on Tuesday morning and that Corean was present
    in the residence at this time.
       Tiegen confirmed that Troy Klug was alive on the morning
    of July 13, 2004, and that even later in the morning Troy
    Klug would have been well enough to walk away.
       Tiegen confirmed that after Kusick observed Troy Klug in
    the garage, Kusick left the garage and had a conversation
    with Corean.
       Tiegen testified that he left Troy Klug alive in Corean’s
    garage on the morning of July 13, 2004, after Kusick and
    Corean left for work.
       Kusick testified that on the morning of July 13, 2004, he
    told Corean that Tiegen had someone that he was holding
    in the garage.
    -9-
    #25001
       Tiegen’s testimony had no impact on the issue of Corean’s
    knowledge of Troy Klug’s presence in her garage at a time
    when Troy Klug was alive and at a time when Corean had
    an opportunity to intervene on Troy’s behalf; the jury
    heard the evidence that Corean chose to provide a place for
    Tiegen to hold Troy Klug.
    [¶20.]       The court also found that Corean’s friends’ testimony confirmed
    Corean’s knowledge of Klug’s confinement in her garage. The court noted: “DeJong
    and Haar testified that on Tuesday between 6:00 and 7:00 p.m., a conversation
    occurred on the porch of the Kusick/Corean residence and that Haar, DeJong and
    Corean discussed the presence of a person in a box in the Kusick/Corean garage.”
    The court further noted that “DeJong testified that she told Corean more than one
    time that they should try to help the person being held in the garage and Corean
    refused.” Finally, the court noted, “[w]hen Corean returned home on Tuesday,
    Kusick testified that he spoke with her and told her that there was still someone
    being held in the garage.” In light of all evidence, we agree with the circuit court
    that Tiegen’s testimony was merely cumulative, it tended to impeach other
    witnesses, and it would not have affected the outcome of the trial.
    [¶21.]       Corean, however, emphasizes that Tiegen testified that Klug was dead
    by 3:00 p.m. on Tuesday, July 13. Corean argues that because Klug “was dead prior
    to [her] knowledge [of the kidnapping], Corean obviously [can] not be guilty of any
    kidnapping or murder charge.” Corean contends that Finding # 40 – in which the
    circuit court found that Tiegen’s testimony “regarding the time of the death of Troy
    Klug lacks credibility,” – is clearly erroneous. We disagree.
    [¶22.]       Tiegen’s credibility was highly suspect. Kindall testified that at the
    time of the kidnapping, Tiegen: had been using methamphetamine; had been awake
    -10-
    #25001
    for approximately one week; and, was not thinking clearly. We also observe that
    Tiegen essentially conceded bias, testifying that (1) Corean was the only one who
    had not testified against him, (2) he bargained for a plea agreement for Corean, and
    (3) he believed Corean was wrongly convicted, “really [getting] a raw deal.” Finally,
    a number of witnesses contradicted Tiegen. The circuit court noted, “[t]he
    testimony of James Kusick, Eric Haar and Abigail DeJong regarding the time of
    death [was] corroborated by the testimony of Dr. Neal Haskell, an entomologist,
    who found that Troy Klug’s death occurred on Wednesday, July 14, 2004, at the
    earliest.” 6 Cook also testified that Troy Klug was still alive on the morning of
    Wednesday, July 14. Therefore Finding # 40 was not clearly erroneous. 7 We agree
    6.    Although Corean argues that “the entomologist’s testimony was based on an
    erroneous date provided to the entomologist by the prosecution,” the circuit
    court’s findings reflect that it considered not only the entomologist’s opinion,
    but also the testimony of Cook, Haar, Kusick, and DeJong in making its
    findings regarding the time of death. Further, the court provided an
    instruction informing the jury that: “You are not bound to accept an expert’s
    opinion as conclusive, but should give to it the weight to which you find it to
    be entitled. You may disregard any such opinion if you find it to be
    unreasonable.”
    7.    Corean also argues that Finding # 26 is clearly erroneous. In that finding,
    the court found: “Eric Haar and Kusick returned to the Kusick/Corean
    residence on Tuesday afternoon at sometime between 4:00 p.m. and 5:00 p.m.
    At that time they observed [Klug] alive in the garage in the [tool] box.”
    Corean claims that Kusick and Haar never testified that Klug was alive at
    that time. Our review of Kusick’s and Haar’s testimony supports Corean’s
    claim. Kusick testified that he saw Klug only “from a distance” when Haar
    opened the tool box. Kusick did not testify that he observed Klug alive at
    that time. Similarly, Haar never testified that he saw Klug alive. Rather,
    Haar said that he “only caught a glimpse” of Klug before he shut the tool box,
    and that “there was no movement, no nothing.” Regardless of whether these
    two witnesses observed Klug alive on Tuesday afternoon, Kusick testified
    that on Tuesday morning, Corean knew that Klug was in the tool box. And,
    other witnesses established that Corean was aware of and aided Klug’s
    (continued . . .)
    -11-

    with the circuit court’s finding that: “Tiegen’s testimony [had] no impact on the
    issue of Corean’s knowledge of Troy Klug’s presence in her garage at a time when
    Troy Klug was alive and at a time when Corean had an opportunity to intervene on
    Troy’s behalf[.]” 8 For these reasons, the circuit court did not abuse its discretion in
    denying Corean’s motion for a new trial.
    [¶23.]         Corean also argues that a new trial is required because the State
    committed a Brady violation. Corean contends that the State, through its “actions”
    in pursuing a capital-murder charge against Tiegen, caused Tiegen to exercise his
    Fifth Amendment rights, “prevent[ing Corean] from obtaining the [exculpatory]
    evidence Tiegen had to provide” until after her trial. See generally Rodriguez v.
    Weber, 
    2000 S.D. 128
    , ¶ 14, 
    617 N.W.2d 132
    , 138 (“Due process under the
    Fourteenth Amendment of the United States Constitution, and Article VI, § 2 of the
    South Dakota Constitution, requires the State to reveal exculpatory evidence to the

    imprisonment Tuesday afternoon and evening. Finally, the jury heard Cook’s
    testimony that Klug was still alive on Wednesday.
    8.       Corean objects to Findings ## 24 and 25, in which the court found that
    according to Agent Gromer’s testimony, “Corean told [Kusick] that she did go
    back [to the garage] in the morning and that she checked and Tiegen was
    gone and she locked everything up.” The court then found that “Tiegen never
    mentioned that the garage was locked and offered no explanations to how he
    was able to even get in the garage which Corean claimed was locked.”
    Corean claims that these findings are erroneous because Agent Gromer
    testified only that “[Kusick] had told [Corean] to check and lock up the shed.
    I don’t remember if she said she did that; but I assumed that she [did]
    because [Kusick] told her to.” (Emphasis added.) Regardless of this
    ambiguity, the jury heard Corean’s own testimony (originally provided at
    Tiegen’s trial) that she returned to her house later Tuesday morning and
    locked the garage.

    defense.” (citing Brady v. Maryland, 
    373 U.S. 83
    , 87, 
    83 S.Ct. 1194
    , 1196-97, 
    10 L.Ed.2d 215
    , 218 (1963))). In considering whether a Brady violation has occurred,
    three questions must be answered:
    1. Was the evidence at issue favorable to the Defendant because
    it is exculpatory or impeaching;
    2. Was the evidence suppressed by the State either willfully or
    inadvertently; and
    3. Did prejudice ensue from the suppression.
    State v. Piper, 
    2006 S.D. 1
    , ¶ 19, 
    709 N.W.2d 783
    , 795. If all three questions are
    answered in the affirmative, a circuit court must grant a new trial. 
    Id.
    [¶24.]       Corean argues that Tiegen’s testimony was unavailable at her trial
    because the State’s action in prosecuting Tiegen for first-degree murder as a capital
    offense delayed his guilty plea. But Corean cites no authority suggesting delay
    caused by a collateral prosecution constitutes State action withholding evidence
    within the meaning of Brady. More importantly, the State was not the cause of
    Corean’s inability to acquire Tiegen’s testimony. Tiegen testified that at the time of
    Corean’s trial, he had already been offered the plea agreement that eliminated a
    possible death sentence. Therefore, the State’s decision to initially pursue a capital
    murder prosecution did not delay the availability of Tiegen’s testimony. As Tiegen
    conceded, the State had removed the death-penalty potential through its plea offer,
    and Tiegen simply elected “not to accept [the plea agreement] at that time.”
    Consequently, even if a Brady violation could occur as the result of a collateral
    prosecution, Corean failed to establish that any State action caused a Brady
    violation.

    II. Whether the circuit court erred in admitting co-conspirator statements.
    [¶25.]        The State introduced three letters that Tiegen wrote to Kindall and
    Cook while Tiegen was incarcerated in the Pennington County jail. The circuit
    court admitted the letters under SDCL 19-16-3(5) (Rule 801(d)(2)) as statements of
    co-conspirators. SDCL 19-16-3(5) (Rule 801(d)(2)) provides that “[a] statement is
    not hearsay if it is offered against a party and is . . . [a] statement by a co-
    conspirator of a party during the course and in furtherance of the conspiracy.” A
    circuit court’s “decision to admit [ ] statements under SDCL 19-16-3(5) is reviewed
    under the clearly erroneous standard.” Tiegen, 
    2008 S.D. 6
    , ¶ 27, 744 N.W.2d at
    588.
    [¶26.]        “Statements made by a co-conspirator are admissible whether or not a
    conspiracy has been charged.” State v. Smith, 
    353 N.W.2d 338
    , 342 (S.D. 1984).
    “When there is substantial evidence of a conspiracy, whether the offense charged is
    conspiracy or not, everything said by [a] conspirator in furtherance of the common
    purpose is deemed to have been said [on] behalf of all parties to the conspiracy.”
    State v. Kidd, 
    239 N.W.2d 860
    , 864 (Iowa 1976). “A statement by a co-conspirator of
    a party during the course and in furtherance of the conspiracy is thus admissible
    against the party as an admission.” 
    Id.
     It is settled that “[t]o satisfy the test of
    admissibility [under SDCL 19-16-3(5) (Rule 801(d)(2))], there need only be a
    showing that there is some reasonable basis for concluding that the statement was
    made in furtherance of the conspiracy.” Tiegen, 
    2008 S.D. 6
    , ¶ 27, 744 N.W.2d at
    588. “Once a conspiracy ha[s] been shown, the burden is upon the conspirator to
    show it has ended.” Kidd, 
    239 N.W.2d at 864
    .
    -14-
    #25001
    [¶27.]         The first letter was from Tiegen to Kindall. The letter advised, “just
    remember. Do not discuss you[r] case with anyone!” Tiegen cautioned: “You also
    need to realize that the interview room (where you talk to your lawyer) is bugged.
    They can’t use the tapes but what they hear could send them places we don’t need
    them going!” Tiegen then warned Kindall: “There are some people we don’t want to
    put any further pressure on. Ok. (James [Kusick] and Jamie [Corean].) Savvay?” 9
    [¶28.]         The circuit court ruled that this letter was “a clear instruction to
    Kindall in furtherance of the conspiracy to conceal the crime.” It found that it was
    “a clear instruction that [Kindall] conduct herself so that co-conspirators, [Kusick]
    and [Corean], are not implicated or involved.” More specifically, “[t]his
    correspondence [was] meant to conceal Kusick and [Corean] and the conspiratorial
    activities that occurred on July 13, 2004, involving the kidnapping and murder of
    Troy Klug.” We agree. “A conspiracy does not terminate with the commission of the
    underlying overt act. It continues thereafter so as to include not only the
    substantive offense but also acts and declarations directed at concealing that
    offense.” State v. Jenner, 
    434 N.W.2d 76
    , 82 (S.D. 1988). “The reason for including
    9.       In addition to her hearsay objection, Corean objected to this letter, pointing
    out that at the post-trial hearing Tiegen testified it was his handwriting but
    he did not remember writing the letter. Corean also pointed out that the
    words “(James and Jamie.) Savvay?” are lighter in color, and Tiegen testified
    that he could not remember if he wrote those words. But there was evidence
    from which the jury could have concluded that Tiegen authored the entire
    letter. Janice Tweedy, a forensic document examiner, testified: “I looked at
    that area because it was lighter than the other area around it.” She opined:
    “I didn’t see any evidence of it being a simulation or a forgery.”
    -15-
    #25001
    these subsequent efforts at concealment is that such acts and declarations further
    the conspiracy by allowing the co-conspirators to escape punishment.” 
    Id.
    [¶29.]       The second letter was from Tiegen to Cook while both were
    incarcerated in the Pennington County jail. Tiegen wrote: “Even if they do find
    some so-called physical evidence, where the hell are they going to get their DNA to
    compare it to?” He assured Cook: “If we were to be convicted they would have to
    find the guy. And believe me they ain’t gonna find nobody unless someone else
    planted somebody.” Tiegen then bragged: “It may have taken me a while to decide
    what to do but once I figured it out, it was the best plan, and I exercised it with
    grinding precision.” Tiegen concluded: “Don’t worry about them finding a body!”
    [¶30.]       The circuit court found these statements were “boasts . . . used by
    [Tiegen] to obtain the confidence of one involved in the conspiracy.” The court
    further found these statements “were made by a co-conspirator (Tiegen) to allay
    apprehension that Cook may have . . . to insure future good relations among the co-
    conspirators.” We agree with the circuit court’s ruling. Bragging, “puffing, boasts,
    and other conversation . . . are admissible when used by the declarant to obtain the
    confidence of one involved in the conspiracy.” Smith, 353 N.W.2d at 344. With
    regards to Tiegen’s statement to not “worry” about finding a body, “[s]tatements
    made by a co-conspirator to allay suspicions are admissible . . . as are statements
    made by a co-conspirator to allay apprehensions that potential co-conspirators may
    have with respect to the conduct of another co-conspirator and designed to ensure
    future good relations among the co-conspirators.” Id.
    -16-
    #25001
    [¶31.]         The third letter was from Tiegen to Cook (nicknamed “Chopper”)
    stating: “Yeah, you know that this was one of the nastiest things I have ever done . .
    . one of the nastiest. . . . If a guy’s gonna make fish food he just as well put it in
    bite-size pieces right!” Tiegen went on: “What the hell. It wasn’t my first rodeo and
    I’m sure it won’t be my last if I stay in the business I’ve been in.” He then told
    Cook: “I want you to know Chopper you are now a part of a group that is bigger and
    more powerful than you will ever know.” And: “When we make it through this it
    will be official.”
    [¶32.]         The circuit court also found these statements “were made by a co-
    conspirator (Tiegen) to obtain the continuing confidence of another co-conspirator
    (Cook),” and that they were “efforts to conceal the crime.” We agree. Like the
    second letter, this letter amounted to “puffing, boasts, and other conversation” that
    Tiegen used to obtain the confidence of a co-conspirator. See id. The statements
    were also made “by a co-conspirator to allay apprehensions that potential co-
    conspirators may have with respect to the conduct of another co-conspirator and
    designed to ensure future good relations among the co-conspirators.” See id.
    [¶33.]         Corean, however, argues that the letters were inadmissible because
    “she was not a co-conspirator of Tiegen’s under any theory,” and that the State
    failed to meet its burden of proving that Corean was part of a conspiracy to kidnap
    Klug. We disagree.
    [¶34.]         There is no dispute that Tiegen and Kindall conspired to kidnap and
    murder Klug. And:
    It is well settled that where the existence of a conspiracy is
    shown, only slight additional evidence is required to connect a
    -17-
    #25001
    particular defendant with the conspiracy. A single act may be
    the foundation for drawing an actor within the ambit of a
    conspiracy if that act is such that one may reasonably infer an
    intent to participate in the unlawful enterprise.
    Estate of Gibbs, 
    490 N.W.2d 504
    , 508 (S.D. 1992). Further, “because conspiracy by
    its very nature is often not susceptible to proof by direct evidence, the existence of
    an agreement may be inferred from all the surrounding facts and circumstances,
    including the acts and declarations of the alleged co-conspirators that may be
    indicative of their concerted action toward a common unlawful goal.” Jenner, 434
    N.W.2d at 81-82. Therefore, when a defendant “is present at the scene of a crime,
    any conduct promoting or facilitating, however slightly, the commission of a crime,”
    may be sufficient. Estate of Gibbs, 490 N.W.2d at 508.
    [¶35.]       In this case, the evidence established that Corean was at her house
    when Tiegen arrived with Klug in the trunk of the car. Thereafter, Kusick informed
    her that Klug had been kidnapped by Tiegen and Klug was being held against his
    will in her garage. We agree with the circuit court’s observation that Corean’s
    participation in the conspiracy was established by:
    Testimony of Eric Haar, James Kusick, Tell Cook and Agent
    Gromer that a conspiracy existed between [Corean], Tory Tiegen
    and others of July 13, 2004. . . . Shortly after Tiegen and
    Kindall arrived at [Corean’s] home, [Corean] was clearly aware
    that Klug had been kidnapped by them and was being held
    against his will. [Corean] knew that Troy Klug was bound and
    gagged in a tool box at her residence. [Corean] knowingly
    joined, participated, and perpetuated the kidnapping by
    providing her residence as a sanctuary for their use while Klug
    remained on her property. [Corean] adopted the purposes and
    objects of the conspiracy by knowingly engaging in actions which
    furthered the object and purpose of the conspiracy.
    -18-
    #25001
    We also observe that DeJong testified that Corean knew that Klug was bound and
    gagged inside the tool box. And, despite DeJong’s pleas to call the police, Corean
    refused, telling DeJong that “the cops [would] get them”; and later, that they needed
    to establish an alibi. This evidence was sufficient to establish Corean’s
    participation in the conspiracy.
    [¶36.]       The circuit court also admitted the letters under the residual hearsay
    exception. That exception provides in part:
    A statement not specifically covered by any of §§ 19-16-30 to 19-
    16-34, inclusive, but having equivalent circumstantial
    guarantees of trustworthiness, is not excluded by § 19-16-4 if the
    declarant is unavailable as a witness and if the court determines
    that:
    (1)    The statement is offered as evidence of a material fact;
    (2)    The statement is more probative on the point for which it
    is offered than any other evidence which the proponent
    can procure through reasonable efforts; and
    (3)    The general purposes of these rules and the interests of
    justice will best be served by admission of the statement
    into evidence.
    SDCL 19-16-35 (Rule 804(b)(6)). “The primary requirement of SDCL 19-16-35
    [(Rule 804(b)(6))] is that the declarant be unavailable to testify at trial.” State v.
    Davi, 
    504 N.W.2d 844
    , 849 (S.D. 1993). In addition to the other statutory
    requirements, and to establish that the statements bear the appropriate guarantee
    of trustworthiness, a circuit court should consider (1) the written or oral nature of
    the evidence, (2) the character of the statements, (3) the relationship between the
    declarant and the witness, (4) the declarant’s motivation, and (5) the circumstances
    under which the statements were made. 
    Id.
    -19-
    #25001
    [¶37.]         Corean contends that trustworthiness was not established. In
    admitting the letters, however, the circuit court applied the required factors,
    finding:
    Having found Mr. Tiegen to be unavailable, I find that the
    information, the statements in the letters have circumstantial
    guarantees of trustworthiness; these are statements between co-
    conspirators; between friends, as a matter of fact. I also find the
    evidence, the hearsay goes to evidence of a material fact. I also
    find that it’s more probative than any other available evidence,
    obviously, if Mr. Tiegen being unavailable, his statement can
    come in, but these letters were sent back and forth between
    prisoners, between Mr. Tiegen and Ms. Kindall and Mr. Tiegen
    and Tell Cook. I also find that the general purpose of the
    hearsay rule and the interest of justice would be served by their
    admissions.
    The court further found that the statements and letters “were trying to keep the
    conspiracy going and trying to hide it.” The court finally found:
    [T]hey were co-conspirators, partners in crime, if you will and
    the motivation in making the statements certainly was
    continuing the conspiracy and some of that analysis that I made
    previously, also sets [sic]; and again, the circumstances under
    which the declarant made the statement[s], again, they were
    both in jail, they were friends, they are co-conspirators; they
    need to be communicating about the things that are very
    relevant and material to this case.
    Under these circumstances, the circuit court did not abuse its discretion in
    admitting the letters as statements of co-conspirators under SDCL 19-16-3(5) (Rule
    801(d)(2)) and as residual hearsay under SDCL 19-16-35 (Rule 804(b)(6)). 10
    10.      Corean argues that the letters are not relevant. We disagree. Evidence is
    relevant if it has “any tendency to make the existence of any fact that is of
    consequence to the determination of the action more probable or less probable
    than it would be without the evidence.” SDCL 19-12-1 (Rule 401). Here, the
    letters were relevant because they established elements of the underlying
    criminal offenses of kidnapping and first-degree murder, elements that the

    III.     Jury Instructions
    [¶38.]         Corean objected to several instructions. 11 Instructions are sufficient
    when, viewed as a whole, they correctly state the law and inform the jury. State v.
    Moss, 
    2008 S.D. 64
    , ¶ 23, 
    754 N.W.2d 626
    , 634. “A trial court has discretion in the
    wording and arrangement of its jury instructions, and therefore we generally review
    a trial court’s decision to grant or deny a particular instruction under the abuse of
    discretion standard.” State v. Cottier, 
    2008 S.D. 79
    , ¶ 7, 
    755 N.W.2d 120
    , 125. To
    constitute reversible error, the instructions must not only be erroneous but also
    prejudicial. 
    Id.
    [¶39.]         Corean objected to an instruction on admissions, arguing that none of
    her out-of-court statements rose “to the level of an admission.” The circuit court
    overruled Corean’s objection, noting her presence at the scene and her conversations
    concealing that Klug was being held against his will. The court ruled that the jury
    should decide “whether or not any of these statements were admissions, [and]
    whether the statement [was] true in whole or in part.”
    ________________________
    (. . . continued)
    State was required to prove to convict Corean of aiding and abetting
    aggravated kidnapping and accessory to murder.
    11.      Corean also makes a general objection to the instructions as a whole, arguing
    that they were incorrect, misleading, confusing, and prejudicial. Because
    Corean does not identify how the instructions were incorrect, misleading or
    confusing as a whole, and because she cites no authority on this issue, we
    decline to address her general objection. See State v. Pellegrino, 
    1998 S.D. 39
    ,
    ¶ 22, 
    577 N.W.2d 590
    , 599 (providing that the failure to cite supporting
    authority on appeal is a violation of SDCL 15-26A-60(6) and the issue is
    thereby waived).
    -21-
    #25001
    [¶40.]       “[A] criminal admission is ‘avowal of a fact or of circumstances from
    which guilt may be inferred[.]’ Admissions are ‘the words or acts of a party-
    opponent, or of his predecessor or representative, offered as evidence against him.’”
    State v. Sabers, 
    442 N.W.2d 259
    , 265 (S.D. 1989) (quoting State v. Stuck, 
    434 N.W.2d 43
    , 54 (S.D. 1988)). Therefore, an admission may include inferences from
    demeanor, conduct, and acts of a defendant.
    [¶41.]       Here, a jury could have inferred guilt from Corean’s acts and
    statements. Kusick testified that Corean knew that Klug was being held in her
    garage, but she did not do anything to help him. Further, DeJong testified that she
    told Corean more than once that they should try to help Klug, but Corean refused,
    concealing the kidnapping and indicating that the parties should establish an alibi.
    The jury could have inferred guilt from these acts and statements because they
    evidenced Corean’s knowledge and intent to provide a sanctuary for Tiegen to
    restrain Klug. The circuit court did not err in giving an instruction on admissions.
    [¶42.]       Corean also objected to the court’s instruction on accomplices. That
    instruction provided in part:
    To render a person an accomplice, the person must in some
    manner knowingly and with criminal intent have aided and
    abetted or have advised and encouraged the commission of the
    criminal act charged. . . . Whether or not any witness in this
    case was an accomplice as defined in these instructions is for the
    jury to determine from all the evidence in this case. However,
    you are instructed that as a mater [sic] of law James Kusick and
    Cynthia Kindall are to be considered accomplices.
    (Emphasis added.) Corean argues that the circuit court should have instructed that
    DeJong, Haar, and Cook were also accomplices as a matter of law. Corean argues
    prejudice because such an instruction would have required that these additional
    -22-
    #25001
    witnesses’ testimony be corroborated. See SDCL 23A-22-8 (“A conviction cannot be
    had upon the testimony of an accomplice unless it is corroborated by other evidence
    which tends to connect the defendant with the commission of the offense. The
    corroboration is not sufficient if it merely shows the commission of the offense, or
    the circumstances thereof.”). The circuit court declined Corean’s request, ruling
    that it was a fact question for the jury whether the “people other than Mr. Kusick
    and Ms. Kindall” were accomplices.
    [¶43.]       “Whether an individual is an accomplice may be a question of law for
    the court or a question of fact for the jury, depending on the state of the evidence.”
    State v. Busack, 
    532 N.W.2d 413
    , 415 (S.D. 1995). “If the facts as to a witness’
    alleged participation in the crime are disputed or susceptible to different inferences,
    the question is one of fact for the jury; otherwise, it is a question of law.” 
    Id.
    [¶44.]       “An accomplice is one who is liable to prosecution for the identical
    offense charged against the defendant on trial.” Id. at 415-16. An accomplice must
    be “legally accountable” for the underlying offense. Id. at 416. In this case, DeJong,
    Haar, and Cook were neither convicted of nor pleaded guilty to the identical
    offenses charged against Corean. Both Haar and DeJong entered into plea
    agreements under which they were not charged and were given immunity, and Cook
    pleaded to misdemeanor misprison of a felony. Additionally, Corean has not
    identified other evidence suggesting that DeJong, Haar, or Cook were legally
    accountable for the underlying offenses as a matter of law. Rather, their level of
    participation in the events surrounding the murder and kidnapping was susceptible
    -23-
    #25001
    to different factual inferences. Consequently, the circuit court correctly concluded
    that it was a jury question whether those individuals were accomplices.
    [¶45.]       Corean has also failed to establish prejudice. The jury was instructed
    that “[w]hether or not any witness in this case was an accomplice as defined in
    these instructions is for the jury to determine from all the evidence in this case.”
    The jury was also instructed on the need for corroboration of accomplice testimony.
    We must infer that the jury followed those instructions in determining the
    corroboration necessary to support the verdict. See generally State v.
    Olhausen, 
    1998 S.D. 120
    , ¶ 11, 
    587 N.W.2d 715
    , 718. The circuit court did not
    prejudicially err in declining to instruct that DeJong, Haar, and Cook were
    accomplices as a matter of law.
    [¶46.]       The court’s instruction on accessory provided:
    In the crime of being an accessory to a crime the defendant must
    render assistance to another with the specific intent to hinder,
    delay or prevent the discovery, detention, apprehension,
    prosecution, conviction or punishment of the other for the
    commission of a crime. Unless the defendant acted with that
    specific intent, the crime was not committed.
    Over Corean’s objection, the circuit court removed the last sentence of the South
    Dakota pattern jury instruction on accessories, which would have also told the jury
    that “there must exist a union or joint operation of acts or conduct and a certain
    specific intent.” The circuit court removed this language, ruling that it was
    surplusage and confusing.
    [¶47.]       To be an accessory, Corean need only have rendered assistance “with
    intent to hinder, delay, or prevent the discovery, detection, apprehension,
    prosecution, conviction, or punishment of another for the commission of a felony.”
    -24-
    #25001
    SDCL 22-3-5. “Rendering assistance” includes “[o]bstruct[ing] anyone by . . .
    deception in the performance of any act which might aid in the discovery, detection,
    apprehension, prosecution, conviction, or punishment of the other person[.]” SDCL
    22-3-5(4).
    [¶48.]       The court’s instruction provided that the crime required both
    rendering assistance to another and specific intent to “hinder, delay, or prevent the
    discovery, detection, apprehension, prosecution, conviction or punishment” of
    another. Therefore, Corean’s requested language on joint operation of acts or
    conduct and specific intent was duplicative of the court’s instruction. Instructions
    that are duplicative or surplusage do not warrant reversal of a jury verdict. See
    State v. McVay, 
    2000 S.D. 72
    , ¶ 18, 
    612 N.W.2d 572
    , 576; Cody v. Edward D. Jones
    & Co., 
    502 N.W.2d 558
    , 564 (S.D. 1993). We fail to see, and Corean fails to
    articulate, how the circuit court’s reasoning for striking the last sentence was in
    error.
    [¶49.]       Corean objected to the court’s instruction on aiding and abetting
    kidnapping. “Any person who, with the intent to promote or facilitate the
    commission of a crime, aids, abets, or advises another person in planning or
    committing the crime, is legally accountable, as a principal to the crime.” SDCL 22-
    3-3. The court’s instruction provided in relevant part:
    One of the elements of the crime of kidnapping as charged in
    Count 3 of the indictment is that the defendant’s purpose was to
    facilitate the commission of a felony.
    The crimes of murder, aggravated assault, possession of a
    controlled substance and maintenance of a place for the use of
    controlled substances are all felony offenses.
    ***
    -25-
    #25001
    A person commits the offense of maintaining a place for the use
    of controlled substances when the person knowingly keeps or
    maintains any place which is resorted to by persons using
    controlled drugs and substances for the purpose of using such
    substances or which is used for the keeping or selling of a
    controlled drug.
    Corean objected to the last paragraph of the instruction that included possession of
    a controlled substance and maintaining a place for the use of controlled substances
    as underlying felonies. The circuit court overruled the objection, finding evidence
    that all four felonies could have been the purpose for the kidnapping and murder.
    [¶50.]         On appeal, Corean argues that Tiegen did not commit the kidnapping
    to maintain a place for the use of controlled substances.12 A circuit court should
    instruct the jury on issues “supported by competent evidence in the record[.]”
    Johnson v. Armfield, 
    2003 S.D. 134
    , ¶ 7, 
    672 N.W.2d 478
    , 481. Whether the
    evidence was sufficient to support an instruction is viewed “in the light most
    favorable to upholding the verdict.” 
    Id.
    [¶51.]         In this case there was sufficient evidence that the kidnapping took
    place for the purpose of keeping or facilitating Tiegen and Kindall’s drug activities
    at Kindall’s and Corean’s houses. Regarding Kindall’s house, there is no dispute
    that both Tiegen and Kindall were in the illicit drug business from Kindall’s house
    in Rapid City. Tiegen testified that he had been staying at Kindall’s house for
    about a week, and Klug came over to Kindall’s house on Monday to purchase
    methamphetamine. Kindall admitted having sold drugs to Klug, and Klug had
    12.      Although Corean objected to the court’s instruction that included the felony of
    possession of a controlled substance, Corean has not objected to that portion
    of the instruction on appeal.
    -26-
    #25001
    owed her money for drugs for about two to three years. Beebe testified that Kindall
    was a drug supplier and had supplied Beebe with methamphetamine. Beebe
    further testified that Klug had sold drugs for Kindall and Kindall was Klug’s
    supplier. Kusick testified that he had also purchased drugs at Kindall’s house and
    Tiegen was supplying methamphetamine to both Kusick and Corean. Considering
    Klug’s lengthy drug debt to Kindall, together with Tiegen’s statement that Klug had
    become “a rat, a snitch,” the jury could have inferred that the murder and
    kidnapping occurred to foster and maintain Tiegen and Kindall’s drug business at
    Kindall’s house.
    [¶52.]       There was also evidence that Tiegen, Kindall, Corean and others were
    using Corean’s house as a place to use illegal drugs. DeJong testified that before
    Tuesday, July 13, she had seen Tiegen at Corean’s house using drugs. DeJong also
    testified that Corean’s house was the place where “quite a few” people went to use
    illegal drugs. Considering all the evidence, a jury could have inferred that the
    kidnapping occurred because Klug was a “snitch,” and Tiegen and Kindall wanted
    to perpetuate the use of Corean’s house for the sale and use of controlled
    substances. We conclude that the circuit court did not abuse its discretion in
    submitting an instruction that included maintaining a drug premises as a purpose
    for the kidnapping.
    IV. Whether there was sufficient evidence to sustain Corean’s convictions
    [¶53.]       Corean claims that there was “no evidence introduced at trial” to
    sustain her convictions. Her claim is viewed in the light most favorable to the
    verdict. State v. Carter, 
    2009 S.D. 65
    , ¶ 44, 
    771 N.W.2d 329
    , 342. The question is
    -27-
    #25001
    whether “there is evidence in the record which, if believed by the fact finder, is
    sufficient to sustain a finding of guilt beyond a reasonable doubt.” 
    Id.
     This Court
    will not resolve conflicts in the evidence, assess the credibility of witnesses, or
    reevaluate the weight of the evidence. 
    Id.
     “If the evidence including circumstantial
    evidence and reasonable inferences drawn therefrom sustain[s] a reasonable theory
    of guilt, a guilty verdict will not be set aside.” 
    Id.
    [¶54.]        Contrary to Corean’s claim, there was sufficient evidence that she
    aided and abetted Klug’s kidnapping. Kusick testified that he talked to Corean at
    least a “couple of times” about Klug being held in the tool box. DeJong testified that
    (1) Corean told DeJong on Tuesday evening “that there was somebody being held in
    the shed,” (2) Corean told DeJong not to call the police, and (3) Corean talked to
    DeJong about establishing an alibi. Finally, Haar testified that he, Corean, and
    DeJong discussed “the body in the box” on Tuesday evening and reached an
    agreement “not to say anything about it.” Ultimately, Kusick, Haar, and DeJong all
    implicated Corean. As the circuit court correctly observed, the jury could have
    inferred that Corean aided and abetted Tiegen by allowing her house to be used as a
    sanctuary to facilitate the kidnapping.
    [¶55.]        There was also sufficient evidence to sustain Corean’s accessory to
    murder conviction. DCI Agent Gromer testified that when the police interviewed
    Corean in September 2004, Corean lied regarding the type of vehicle that Tiegen
    was driving on Tuesday morning. She informed the police that Tiegen was driving a
    red pickup, as opposed to Kindall’s black Nissan that was used to transport Klug.
    Agent Gromer testified:
    -28-
    #25001
    [W]e got to talking again about Thursday or excuse me, Tuesday
    morning when Tiegen had came [sic] early in the morning and at
    that point in time she said that [Tiegen] was driving a red
    pickup. And said that she remembered that because she walked
    by it as she walked out of the house that morning to go to work.
    When Agent Gromer was asked if Corean’s statement surprised him, he replied, “It
    did because earlier she had said that he was driving the black Nissan.” Agent
    Gromer testified that he then asked Corean about this discrepancy, and Corean told
    him that “she was sure that it was a red and silver pickup.” Agent Gromer further
    testified that the day after this interview, he stopped at Corean’s work, showed her
    a photograph of Tiegen’s pickup, and Corean “identified the pickup as the one that
    was at her house.” The jury could have concluded that this was deception by Corean
    intended to assist Tiegen by obstructing the authorities’ investigation. See supra ¶
    47 (setting forth the elements of an accessory under SDCL 22-3-5 and 22-3-5(4)).
    [¶56.]        Corean also argues that the evidence was insufficient because there
    was no corroborative evidence of accomplice testimony. “[T]here is[, however,] no
    requirement that every material fact testified to by [an] accomplice be confirmed by
    corroborative evidence.” State v. Smithers, 
    2003 S.D. 128
    , ¶ 33, 
    670 N.W.2d 896
    ,
    903. “The rule is satisfied if such evidence in some substantial degree (1) tends to
    affirm the truth of the testimony of the accomplice, and (2) tends to establish the
    guilt of the defendant. Circumstantial evidence may be sufficient to corroborate the
    testimony of an accomplice[.]” State v. Giuliano, 
    270 N.W.2d 33
    , 39 (S.D. 1978).
    “Where such evidence of corroboration appears, its weight, credibility, and
    sufficiency is for the jury.” 
    Id.
    -29-
    #25001
    [¶57.]       We initially observe that Corean’s own testimony corroborated other
    witnesses. Corean admitted that Tiegen was at her house on Tuesday morning and
    that she left work to check if Tiegen had left and to lock the garage. Corean also
    admitted that Tiegen was a good friend and that he had been providing her with
    methamphetamine. She further admitted that Tiegen was at her house with the
    black Nissan. Nevertheless, Agent Gromer indicated that Corean lied or covered-up
    her participation. Corean declined to tell him anything about her actions or seeing
    Tiegen. Corean further confirmed that DeJong was a good friend of hers, and that
    it was possible that several of the witnesses, including DeJong, were at her house
    on Wednesday. That would have placed those witnesses in a position from which
    they could have made the observations they related at trial.
    [¶58.]       Additionally, the kidnapping and murder were clearly corroborated.
    And, with respect to Corean’s defense regarding untimely knowledge of the
    kidnapping, the circuit court found that “[t]he [impeaching] testimony of James
    Kusick, Eric Haar and Abigail DeJong regarding the time of death [was]
    corroborated by the testimony of Dr. Neal Haskell, an entomologist, who found that
    Troy Klug’s death occurred on Wednesday, July 14, 2004, at the earliest.”
    [¶59.]       Finally, as previously noted, it is significant that Kusick, Haar, and
    DeJong have never been convicted of the offenses for which Corean was tried, and
    they were not accomplices as a matter of law. Therefore, it was for the jury to
    determine whether their testimony required corroboration. See supra ¶ 45.
    Considering all the evidence, together with the fact that it was the jury’s
    prerogative to determine whether corroboration was even necessary, there was
    -30-
    #25001
    sufficient evidence for the jury to have convicted Corean. See Olhausen, 
    1998 S.D. 120
    , ¶ 11, 
    587 N.W.2d at 718
     (“The testimony of the accomplice need not be
    validated by evidence adequate to carry a conviction.”). As indicated by the circuit
    court at sentencing, “I sat through the trial and find more than sufficient credible
    evidence to support both verdicts.” The evidence and the natural inferences drawn
    therefrom sustain a reasonable theory of guilt. See Carter, 
    2009 S.D. 65
    , ¶ 44, 771
    N.W.2d at 342.
    V. Whether Corean’s sentence constitutes cruel and unusual punishment
    [¶60.]       Corean argues that her mandatory life sentence for aiding and abetting
    aggravated kidnapping is cruel and unusual punishment because it is grossly
    disproportionate to the crime and to the other parties’ sentences. She also asserts
    gross disproportionality because she alleges the sentence was more than necessary
    to protect the public and provide for rehabilitation, and that the court failed to
    consider mitigating circumstances.
    [¶61.]       But aiding and abetting aggravated kidnapping is a Class A felony. As
    indicated by the circuit court in pronouncing her sentence, “[t]here is no discretion;
    there is no leniency that can be given under the law. . . . The law is clear, it’s a
    Class A felony, life imprisonment and no possibility of parole under that sentence.”
    See SDCL 22-6-1(1) (“A lesser sentence than death or life imprisonment may not be
    given for a Class A.”).
    [¶62.]       We have previously acknowledged that no downward departure is
    permitted under mandatory sentencing even “if mitigating circumstances exist[ed].”
    See State v. Smiley, 
    2004 S.D. 119
    , ¶ 3, 
    689 N.W.2d 427
    , 429. This Court has
    -31-
    #25001
    rejected the arguments that a mandatory life sentence violates the Eighth
    Amendment and that a sentencing court should retain discretion to consider
    mitigating factors to allow for a sentence less than life. See Owens v. Russell, 
    2007 S.D. 3
    , ¶ 29, 
    726 N.W.2d 610
    , 620. Notwithstanding this inability to consider
    mitigating factors, “[t]here is no constitutional basis” for Corean’s arguments: they
    “should be addressed to the [L]egislature.” See 
    id.
     See also Harmelin v. Michigan,
    
    501 U.S. 957
    , 995, 
    111 S.Ct. 2680
    , 2701, 
    115 L.Ed.2d 836
     (1991) (stating that the
    defendant’s “‘required mitigation’ claim, like his proportionality claim, does not find
    support in our death penalty jurisprudence”); Steichen v. Weber, 
    2009 S.D. 4
    , ¶ 30,
    
    760 N.W.2d 381
    , 394 (stating that, when asked to review the proportionality of a
    sentence, this Court gives the “utmost deference to the Legislature”).
    [¶63.]       We believe the same principles apply to a mandatory life sentence for
    kidnapping. “The Legislature sanctioned life imprisonment for particularly
    egregious conduct such as kidnapping[.]” State v. Guthmiller, 
    2003 S.D. 83
    , ¶ 45,
    
    667 N.W.2d 295
    , 310. In upholding a life sentence for kidnapping, Iowa has
    recognized that “[k]idnapping is one of the most serious of all crimes. By its very
    nature it involves violence or forcible restraint.” Lamphere v. State, 
    348 N.W.2d 212
    , 220 (Iowa 1984) (citing In re Maston, 
    33 Cal.App.3d 559
    , 563, 
    109 Cal.Rptr. 164
    , 167 (1973)). Thus, “[t]he severity of punishment . . . can be explained by the
    degree to which the legislature has deplored this [ ] crime.” 
    Id.
     The Eighth Circuit
    has found that a legislatively mandated life sentence for kidnapping is severe, but it
    is not “so disproportionate to the crime as to be unconstitutional.” Hatter v. Iowa
    Men’s Reformatory, 
    932 F.2d 701
    , 703 (8thCir. 1991). Even more to the point, the
    -32-
    #25001
    Eighth Circuit has found that a legislatively mandated life sentence for aiding and
    abetting kidnapping is not grossly disproportionate. See Simmons v. State of
    Iowa, 
    28 F.3d 1478
    , 1483 (8thCir. 1994) (concluding “that the Iowa mandatory
    sentence of life imprisonment without parole is not grossly disproportionate to
    [defendant’s] crime of aiding and abetting the restraint and torture of her seven-
    year-old child”). Similarly, we have concluded that a mandatory life sentence for
    conspiracy to commit a murder that never came to fruition was not cruel and
    unusual punishment. See State v. Kaiser, 
    526 N.W.2d 722
    , 726 (S.D. 1995)
    (analyzing the issue under the shock-the-conscience test).
    [¶64.]       The Supreme Court has noted that, outside the context of capital cases,
    the proportionality principle only comes into play in the extreme example, if for
    example a legislature made overtime parking a felony punishable by life
    imprisonment. Ewing v. California, 
    538 U.S. 11
    , 21, 
    123 S.Ct. 1179
    , 1185, 
    155 L.Ed.2d 108
     (2003). Corean’s case is not such an extreme example. Considering the
    torture and depravity involved in this case, Corean’s active participation in
    facilitating the crime, and the legislatively mandated sentence for this offense, we
    must defer to the Legislature and reject Corean’s gross disproportionality
    argument.
    [¶65.]       Affirmed.
    [¶66.]       GILBERTSON, Chief Justice, and KONENKAMP, MEIERHENRY,
    and SEVERSON, Justices, concur.
