delivered the Opinion of the Court.
T 1 In this original proceeding pursuant to C.A.R. 21, we consider the trial court's determination regarding the admissibility of alternate suspect evidence offered by the defendant, Kevin F. Elmarr. In 2009, a jury found Elmarr guilty of first degree murder after deliberation for strangling his ex-wife. In an unpublished decision, the court of ap
T2 The People now. petition this court for relief under C.AR. 21, arguing that the trial court failed on remand to conduct the proper analysis to determine the admissibility of the alternate suspect evidence-in particular, evidence of other similar acts committed by the alternate suspect and statements made by the alternate suspect to law enforcement. The People contend that this area of the law has generated considerable confusion and ask this court to clarify the proper framework for examining the admissibility of such evidence.
T 3 We agree with the People that the trial court failed to conduct the proper analysis and thus make absolute our rule to show cause. The trial court understood the court of appeals' decision remanding the case to require admission of the alternate suspect evidence, We conclude, however, that the court of appeals, relying on People v. Muniz,
I. Facts and Procedural History
T 4 On May 23, 1987, hikers discovered the body of Carol Murphy near a campsite in Boulder County's Lefthand Canyon. Murphy had been killed by ligature strangulation, her throat had been cut, and branches and foliage had been placed over her body. The day before, Murphy had told several people that she and her "ex" were going to the mountains on his motorcycle for a picnic. That same day, Elmarr, Murphy's ex-husband, told his sister that he and Murphy were going on a picnic in the mountains. Two witnesses identified Elmarr as the man who had accompanied Murphy on the day the prosecution believes she was killed. Nearly twenty years later, on February 1, 2007, the prosecution charged Elmarr with first degree murder for Murphy's death.
T5 Before trial, Elmarr notified the court that he intended to introduce evidence pertaining to several alternate suspects. This list included Curtis Murphy, the victim's husband, whom she was in the process of divore-ing; William Taylor, the victim's boyfriend; Clifton St. Denis, a homeless man who had been camping near where the victim's body was discovered; Andrew Lloyd, who had previously threatened the victim; Blaine Luzm-oor, who had been in a prior romantic relationship with the victim; and an unidentified man named "Billy." The People moved to exclude all alternate suspect evidence. Following a hearing, the trial court issued an order excluding evidence of all alternate suspects. 1 Only the evidence regarding St. Denis at issue here.
16 Elmarr sought to introduce evidence suggesting that St. Denis murdered the vie-tim. In addition to evidence linking St. Denis to the crime seene, Elmarr sought to introduce statements St. Denis made to detectives purportedly confessing to the murder and evidence of two other crimes committed by St. Denis involving acts of strangulation in the same calendar year as the homicide in this case.
T7 St. Denis was considered a suspect in the case for several years. He was camping in the area where the victim's body was found. Detectives interviewed him about a year later while he was confined at a state mental hospital. St. Denis admitted to being in the area when the murder occurred. He described the location where the victim's body was found and stated that a suitcase
T8 During the interview, St. Denis also made statements about having killed his roommate, Molly Currier, in New York. When asked if the victim in this case "got it the same way that Molly did in New York," he replied, "[Yle[alh, in the end ... that's why I said I think it was me. In the end when I think she was sereamin' I had her...." He stated, "I don't know if I stabbed her or not. I don't remember." St. Denis acknowledged being under the influence of drugs when he was interviewed. He later recanted his confession to killing the victim in this case.
T9 Currier was found dead in her apartment in February 1987. St. Denis admitted to strangling her and later entered a plea of not guilty by reason of insanity in that case. 2 In December 1987, St. Denis also strangled and threatened his roommate and girlfriend, Holly Lutz, with a knife. He confessed to her attempted murder, and, after he waived a jury trial, the court found him not guilty by reason of insanity. St. Denis has since died.
110 In its pretrial order analyzing the admissibility of this evidence, the trial court discussed People v. Muniz,
{11 The trial court determined that the evidence regarding St. Denis pertained only to motive and opportunity, not identity, and thus the Muniz "totality of the cireum-stances" test was inapplicable. Applying the "direct connection" test instead, the trial court concluded that the alternate suspect evidence regarding St. Denis was not admissible. In addition to finding that St. Denis's statements contained discrepancies, the trial court concluded that there was no evidence of acts directly connecting St. Denis to the charged crime, nor was there any motive, even assuming St. Denis had the opportunity to commit the crime due to the proximity of his campsite. The court's order did not discuss hearsay rules, but it noted that it was confident St. Denis was not lucid when he stated he "coulda" committed the murder. The court therefore granted the People's motion in limine to exelude the alternate suspect evidence.
112 Following trial, a jury found Elmarr guilty of first degree murder after deliberation. The trial court sentenced Elmarr to life with the possibility of parole after forty years. On appeal, Elmarr argued, inter alia, that by excluding evidence of alternate suspects, the trial court prevented him from presenting evidence in his defense in violation of his due process rights under the Fourteenth Amendment and article II, seetion 25 of the Colorado Constitution. See People v. Elmarr, No. 09CA2462, slip op. at 4,
13 The court of appeals agreed with El-marr that the trial court erroneously exelud-ed alternate suspect evidence regarding St. Denis and Charles Murphy. Id. at 2. 3
15 The court of appeals further held that, contrary to the trial court's ruling, St. Denis's confession was "not so palpably incredible and totally unbelievable to justify rejecting it as a matter of law." Id. Although it did not address evidentiary rules regarding hearsay, the court of appeals observed that St. Denis's confession was corroborated by other evidence, including details he provided about the crime seene and his description of the suitease found in the area. Id. at 18. It reasoned that these details, in conjunction with St. Denis's history of strangling women, his proximity to the location where the body was found, and his statement that he "believed" he had killed the victim, made the credibility of his confession an issue for the jury to resolve. Id.
{16 The court of appeals concluded that when all the evidence concerning St. Denis is considered, it was "sufficient to permit a reasonable juror to have a reasonable doubt about [the] defendant's guilt because it tended to make [the] defendant's identity as the perpetrator less probable." Id. at 15. Finally, the court of appeals noted that it was "not persuaded that the evidence's probative value was substantially outweighed by other considerations such as unfair prejudice, confusion of the issues, or potential to mislead the jury." Id. The court of appeals held that the trial court's error required reversal and remanded the case for a new trial. Id. at 17-19, 34. The People filed a petition for writ of certiorari, which this court denied. People v. Elmarr, No. 13SC280,
117 On remand, Elmarr filed a notice of intent to introduce evidence of other bad acts by St. Denis, as well as a notice of intent to introduce statements by St. Denis under CRE 807s residual hearsay exception. The People moved to exclude both the other acts evidence and the hearsay statements. Following a hearing, the trial court (with a different judge presiding) issued an order denying both of the People's motions. The People then petitioned this court pursuant to C.A.R. 21 for review of the trial court's order.
II. Jurisdiction
118 This court may exercise its original jurisdiction under C.A.R. 21 to review a trial court's evidentiary rulings where the petitioning party has no other adequate appellate remedy. C.A.R. 21; see People v. Dist., Court,
"19 If the evidence challenged by the prosecution is improperly admitted on retrial, there may not be a remedy on appeal, as jeopardy will attach and the People cannot retry the defendant if he is acquitted. As a result, we conclude that the People have no other adequate remedy and exercise of our original jurisdiction is appropriate. See id.; see also People v. Salazar,
III. Standard of Review
120 Trial courts have broad discretion in determining the admissibility of evidence based on its relevance, its probative value, and its prejudicial impact. People v. Ibarra,
IV. Analysis
121 This case requires us to clarify the framework for the admissibility of alternate suspect evidence, including evidence of other crimes, wrongs, or acts committed by the alternate suspect.
122 We hold that the admissibility of alternate suspect evidence ultimately depends on the strength of the connection between the alternate suspect and the charged crime. To be admissible, alternate suspect evidence must be relevant (under CRE 401) and its probative value must not be sufficiently outweighed by the danger of confusion of the issues or misleading the jury, or by considerations of undue delay (under CRE 403).
123 The touchstone of relevarice in this context is whether the alternate suspect evidence establishes a non-speculative connection or nexus between the alternate suspect and the crime charged. Where the evidence concerns other acts by the alternate suspect, a court must look to whether all the similar acts and cireumstances, taken together, support a finding that the same person probably was involved in both the other act and the charged erime. CRE 404(b) principles guide this analysis.
$24 Where the evidence concerns statements by the alternate suspect, a court must determine whether the alternate suspect's statements meet the requirements of CRE 804(b)(8) or any other applicable hearsay exception. Even assuming the statements are admissible under the rules governing hearsay, the court must still determine whether the statements, along with the other proffered alternate suspect evidence, establish the requisite non-speculative connection tying the alternate suspect to the charged crime.
125 Finally, even relevant alternate suspect evidence may be excluded if its probative value is substantially outweighed by countervailing policy considerations under CRE 403, such as the danger of confusion of the issues or misleading the jury, or by considerations of undue delay.
A. General Evidentiary Limits on the Constitutional Right to Present a Defense ,
126 "Whether rooted directly in the Due Process Clause of the Fourteenth Amendment or in the Compulsory Process or Confrontation Clauses of the Sixth Amendment, the Constitution guarantees criminal defendants a meaningful opportunity to present a complete defense." Holmes v. South Carolina,
127 However, the right to present a defense is generally subject to, and constrained by, familiar and well-established limits on the admissibility of evidence. As a fundamental matter, evidence must be relevant to be admissible. CRE 402. Relevant evidence is evidence "having 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." CRE 401. And even relevant evidence may be excluded "if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence." CRE 408.
B. Purpose of Alternate Suspect Evidence
128 The relevance and probative value of alternate suspect evidence must be examined in light of the purpose such evidence serves. In a criminal prosecution,
129 Alternate suspect evidence seeks to cast reasonable doubt on the material element of identity. In other words, evi-denee indicating that someone else committed the crime tends to make the defendant's identity as the perpetrator less probable and, thus, creates reasonable doubt as to the defendant's guilt. 5 ‘
130 A defendant might seek to present one or more forms of evidence suggesting that an alternate suspect committed the crime. Among other things, the defendant might seek to show that someone else: had a motive to commit the erime; had an opportunity to commit the crime; confessed to the crime or otherwise engaged in behavior indicating his involvement; is linked to physical evidence of the crime; or committed similar acts or crimes. All such evidence seeks to tie the alternate suspect to the charged crime, thus casting reasonable doubt on the identity of the defendant as the perpetrator of the charged erime.
C. Framework for Admissibility of Alternate Suspect Evidence
1 31 Regardless of its form, the admissibility of this type of evidence in a given case ultimately depends on the strength of the connection between the alternate suspect and the charged crime. Because there is a need to place reasonable limits on collateral issues, - and to avoid encouraging the jury to speculate, see People v. Perez,
1. Relevance
182 The touchstone of relevance in this context is whether the alternate suspect evidence establishes a non-speculative connection or nexus between the alternate suspect and the crime charged. That is, the alternate suspect evidence must create more than just an unsupported inference or possible ground for suspicion. Perez,
133 In People v. Mulligan,
134 Although our holding in Mulligan has been described by the court of appeals as the "direct connection" test, the case simply stands for the principle that evidence merely showing that someone else had a motive or opportunity to commit the charged crime-without other additional evidence circumstantially or inferentially linking the alternate suspect to the charged crime-pres: ents too tenuous and speculative a connection to be relevant because it gives rise to no more than grounds for possible suspicion. Importantly, our holding in Mulligan was not intended to establish a specific "test" for evidence of an alternate suspect's motive or opportunity but instead reflects the overarching principle that, to be relevant, alternate suspect evidence must establish a non-speculative connection or nexus between the alternate suspect and the crime charged. In short, mere motive or opportunity is insufficient; a defendant must proffer something "more" to establish the non-speculative connection.
2. Other Acts Evidence Offered by a Defendant
135 Sometimes, the "more" offered to establish the non-speculative connection between the alternate suspect and the charged crime is evidence that the alternate suspect committed other similar acts or crimes. Under CRE 404(b), "[elvidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith." Such evidence may be admissible, however, for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident. Id. This rule has roots in the common law principle that a defendant should be tried only for the offense for which he stands charged. See Stull v. People,
136 CRE 404(b) is not, on its face, limited to evidence offered by the prosecution regarding similar acts committed by the defendant. However, the concern for prejudice to the defendant that gave rise to the common law rule that underpins CRE 404(b) does not exist when the defendant offers other acts evidence of an alternate suspect. Salazar, 118, 272 P.B8d at 1072; People v. Flowers,
137 When discussing the admissibility of other acts evidence offered by a defendant to link an alternate suspect to the charged crime, this court has not expressly referred to CRE 404(b) but has described the analysis as one to be decided on a case-by-case basis, . according to "general relevancy considerations." Salazar, ¶ 18,
138 In Flowers, this court adopted the court of appeals' formulation of the test in Bueno,
139 Despite the "more lenient standard of admissibility" for defense-proffered other acts evidence that we adopted in Flowers, id. at 919, (quoting Bueno,
T 40 In the alternate suspect context, however, the overarching relevance inquiry remains whether the evidence, taken collectively, establishes a non-speculative connection between the alternate suspect and the charged crime. Contrary to the court of appeals' analysis in Muniz, we have not established separate tests for the admissibility of other acts evidence based on whether the evidence pertains to an alternate suspect's motive or opportunity or, instead, to identity.
3. Hearsay Statements
1 41 Where a defendant seeks to introduce an alternate suspect's statements or confession, evidentiary rules regarding hearsay come into play. ° Relevant here, CRE 804(b)(8) permits the introduction of a hearsay statement of an unavailable declarant that:
(A) a reasonable person in the declarant's position would have made only if the person believed it to be true because, when made, it was so contrary to the declarant's proprietary or pecuniary interest or had so great a tendency ... to expose the declarant to civil or criminal liability; and
(B) is supported by corroborating cireum-stances that clearly indicate its trustworthiness.
¶ 42 A trial court must determine whether the alternate suspect's statements meet the requirements of CRE 804(b)(8) or any other applicable hearsay exception. Even assuming the statements are admissible under the rules governing hearsay, the court must still determine whether the statements, along with the other proffered alternate suspect evidence, establish the requisite non-speculative connection tying the alternate suspect to the charged crime.
4. CRE 403 Analysis
43 Even relevant alternate suspect evidence may be excluded if its probative value
144 In balancing probative value against the countervailing policy considerations of CRE 403, an item of evidence should not be viewed as an island. People v. Saiz,
V. Conclusion
45 Neither the court of appeals nor the trial court properly analyzed the admissibility of the alternate suspect evidence in this case. Because the trial court is in the best position to evaluate this evidence under the framework established in this opinion, we make absolute our rule to show cause and remand this case tp the trial court for further proceedings consistent with this opinion.
