delivered the opinion of the court.
The question in this case is whether, in a murder prosecution, evidence that the defendant killed two other persons was properly admitted as other-crime evidence for the purpose of establishing the defendant’s identity as the perpetrator of the murder charged against him. Resolution of that question requires a consideration of the appropriate standards for admitting other-crime evidence under the Colorado Rules of Evidence. The court of appeals held that a trial court, before admitting other-crime evidence, must consider the evidence of each crime independently of all other evidence in the case and then must determine whether the proponent of the other-crime evidence establishes by clear and convincing evidence the identity of the defendant as the perpetrator of the other crime. The court of appeals accordingly vacated the defendant’s conviction for first degree murder and remanded the case to the trial court for further proceedings consistent with the standards for admissibility articulated in its opinion. We reverse the judgment of the court of appeals and reinstate the judgment of conviction entered by the trial court.
I.
The defendant, Ronald Garner, was charged with first degree murder after deliberation and felony murder by causing the death of Tammera Sue Wilson during the commission or attempted commission of sexual assault on or before July 1, 1982.
The prosecution’s case was built on circumstantial evidence. It was the prosecution’s theory that the defendant had an intimate relationship with the victim, who was a trainee-employee at a Winchell’s Do-nut shop managed by the defendant, and that when the victim tried to end the relationship the defendant sexually assaulted and strangled her to death in her apartment. Prior to trial, the trial court conducted a hearing on the prosecution’s motion to offer other-crime evidence during the trial for the purpose of establishing the identity of the defendant as the perpetrator of the murder charged against him. The prosecution presented evidence at the hearing that the defendant had strangled two other women with whom he had an intimate relationship.
The evidence of one of the other crimes related to the strangulation death of the defendant’s wife, Lyric Garner, on February 11, 1970. Shortly prior to her death, Mrs. Garner told her mother that she wanted to leave the defendant. On the day of her death the defendant flagged down a police officer and told the officer that he was not able to awaken his wife. The officer followed the defendant to his apartment and found Lyric Garner’s nude body on the bedroom floor. The badly beaten body was covered up to the neck with a blanket. The defendant told the police that he had slapped his wife during an argument over their cat and then had left their apartment. An autopsy was performed, and it was determined that Mrs. Garner died from manual strangulation. The defendant was charged in 1970 with the first-degree murder of his wife and entered a guilty plea to voluntary manslaughter.
The evidence of the other crime related to the 1984 strangulation death of Jennifer Della Costa, who had been participating in a six-week training program at a Winchell’s Donut shop managed by the defendant.
The trial court ruled that Colorado law did not require a separate consideration of the evidence relating to each crime, independently of any other evidence, in determining the admissibility of the other-crime evidence, but rather required the court to determine the admissibility of other-crime evidence by considering all the evidence in the case, including the other-crime evidence as well as the evidence relating to the crime in question. Under that standard, the trial court determined that the crime charged against the defendant and the two other homicides had sufficiently similar features as to establish by clear and convincing evidence the defendant’s identity as the perpetrator of the two other crimes. The trial court accordingly ruled that the other-crime evidence would be admitted into evidence at trial.
At trial, the prosecution’s evidence showed that the victim was an employee at a Winchell’s Donut shop managed by the defendant and was involved in an intimate relationship with the defendant. During the evening of June 30, 1982, the victim met with Susan Bedard, one of her friends, and told her that she wanted to break off her relationship with the defendant and had spoken to the defendant that very day but had forgotten to retrieve the key to her apartment from him. Later that evening the defendant was socializing with friends at an apartment next to the victim’s apartment and was seen entering the victim’s apartment on two occasions.
The prosecution’s evidence showed that the defendant was one of the last persons known to have been with the victim during the evening of June 30, 1982, and that on the following day the victim’s mother went to the victim’s apartment and found her dead daughter’s body lying face down in bed, scantily clothed, and with blankets pulled up to her head. The body was badly bruised, and an autopsy examination indicated that the victim had been sexually assaulted and had been strangled to death. Semen stains were discovered on the victim’s bedding, and serological testing established that some of the semen could have come from the defendant. In addition, several hairs were found on the victim’s bed and on a blanket in the victim’s apartment. Expert testimony established that some of these hairs matched the defendant’s head and pubic hair.
The prosecution offered into evidence the other-crime evidence previously ruled admissible. The trial court instructed the jury that such evidence was admitted for the limited purpose of establishing the defendant’s identity as the perpetrator of the crime charged against him. A similar limited-purpose instruction was included in the court’s charge to the jury at the conclusion of the evidence.
The defendant did not testify in his defense. The defense evidence consisted of the testimony of an expert witness who stated that, in addition to hairs consistent with those of the defendant found in the victim’s apartment, there were several other hairs recovered from various items in the apartment that originated from persons other than the defendant. The jury found the defendant guilty of first degree murder, and the court imposed a sentence of life imprisonment.
On appeal, the court of appeals vacated the judgment of conviction and remanded the case to the trial court for additional findings. The court of appeals held that this court’s decision in People v. Botham,
II.
Although the Colorado Rules of Evidence provide the controlling evidentiary norms for resolving this case, we believe it appropriate to briefly review preexisting Colorado case law on the admissibility of other-crime evidence, since it was that preexisting law upon which the court of appeals primarily relied in deciding this case. Prior to the adoption of the Colorado Rules of Evidence, which became effective on January 1, 1980, Colorado decisional law adhered to the exclusionary principle that, subject to narrow exceptions, evidence of other crimes was not admissible as proof of the accused’s guilt with respect to the crime charged. E.g., People v. Lucero,
[ A] presumption of guilt should not be generated against an accused by showing that he committed a crime indicative that he is a depraved person who likely would commit the crime for which he is being tried. Basic to our criminal law concepts is the commandment that: “Thou shalt not convict a person of an offense by proof that he is guilty of another.”
Bearing in mind that evidence of similar acts has inhering in it damning innuendo likely to beget prejudice in the minds of jurors, and that such evidence tends to inject collateral issues into a criminal case which are not unlikely to confuse and lead astray the jury, it becomes exigent that courts observe the fine balance in regard to such evidence that must exist between the necessity of proof on the part of the prosecutor and the danger of unfair prejudice to the defendant.
Because other-crime evidence exposes an accused to the risk of being found guilty on the crime charged due to bad character rather than on the basis of the evidence relating to the crime charged, Lucero,
When other-crime evidence qualified for admission under one of the exceptions to the general rule of exclusion, our prior case law required trial courts, upon admitting the evidence, to instruct the jury at that time “as to the limited purpose for which the evidence is being received and for which the jury may consider it” and to repeat this limited-purpose instruction in the general instructions to the jury at the close of the evidence.

III.
We have not previously considered either the quantum of proof or the procedural protocol for resolving the admissibility of other-crime evidence under the Colorado Rules of Evidence, but we have addressed other issues under the Rules that are somewhat related to these issues. Those decisions, along with the structure and text of the Rules themselves, demonstrate that the Rules have significantly changed the preexisting law relating to the admissibility of other-crime evidence.
A.
Although the Rules are silent on the quantum of proof applicable to questions of admissibility, we have adopted the preponderance-of-evidence standard as the controlling norm for determining preliminary questions relating to admissibility. For example, we held in People v. Montoya,
A fact is established by a preponderance of the evidence when, upon consideration of all the evidence, the existence of that fact is more probable than its nonexistence. See Page v. Clark,
Under our case law predating the Colorado Rules of Evidence, the determination of preliminary questions concerning the admissibility of other-crime evidence was to be made by the trial court. Honey,
CRE 104(a) provides that, subject to the provisions of subdivision (b) of Rule 104, preliminary questions concerning the admissibility of evidence shall be determined by the trial court and that the trial court shall not be bound by the Rules of Evidence, except with respect to privileges, in making that determination. CRE 104(b) states that “[w]hen the relevancy of evidence depends upon the fulfillment of a condition of fact, the court shall admit it upon, or subject to, the introduction of evidence sufficient to support a finding of the fulfillment of the condition.”
Subdivision (a) of CRE 104 addresses situations in which preliminary questions concerning the admissibility of evidence depend upon the application of policy considerations, such as those relating to the competency of a witness to testify, the existence of a privilege, the applicability of hearsay exceptions, or other protective policies of exclusionary rules. See Burlington Northern Railroad Co. v. Hood,
The Colorado Rules of Evidence do not answer whether preliminary questions concerning the admissibility of other-crime evidence should be resolved under CRE 104(a) or CRE 104(b). In Huddleston v. United States,
We agree with that part of the Huddleston analysis which requires a trial court, in ruling on the admissibility of other-crime evidence, to consider all the evidence in the case. A trial court, in other words, should not restrict itself to a consideration of the evidence relating to a particular other crime, independently of all other evidence in the case. “The sum of an evidentiary proposition,” as the Court noted in Huddleston, “may well be greater than its constituent parts,” and “individual pieces of evidence, insufficient in themselves to prove a point, may in cumulation prove it.”
The People urge us to adopt that part of the Huddleston decision which relegates the resolution of preliminary questions concerning the admissibility of other-crime evidence to Rule 104(b). We acknowledge that CRE 104 is textually identical to Fed. R.Evid. 104 and that the Supreme Court’s interpretation of the Federal Rules is certainly entitled to careful consideration. We are satisfied, however, that Colorado’s longstanding restrictive policy concerning the admissibility of other-crime evidence militates against adoption of that part of the Huddleston analysis.
As previously discussed in Part II of our opinion, Colorado decisional law over the years has adhered to the exclusionary principle that, subject to narrow exceptions, the inherent prejudice in other-crime evidence renders such evidence generally inadmissible in a criminal prosecution. The basic reasons for excluding other-crime evidence were set forth in Stull,
C.
In ruling on the admissibility of other-crime evidence, the trial court must consider the totality of all the evidence in the case, except evidence relating to privileged information, and must apply the preponderance-of-evidence standard in deciding whether it is more likely than not that the factual conditions precedent to admitting
Read together, these rules require a four-part analysis to determine whether evidence of prior acts is admissible. First, we must ask whether the proffered evidence relates to a material fact, i.e., a fact “that is of consequence to the determination of the action.” CRE 401; [People v. Carlson,712 P.2d 1018 , 1021 (Colo.1986)]. If it does, we proceed to the second question: is the evidence logically relevant, i.e., does it have “any tendency to make the existence of [the material fact] more probable or less probable than it would be without the evidence?” CRE 401; Carlson,712 P.2d at 1021 . If the evidence is logically relevant, we then must determine whether the logical relevance is independent of the intermediate inference, prohibited by CRE 404(b), that the defendant has a bad character, which would then be employed to suggest the probability that the defendant committed the crime charged because of the likelihood that he acted in conformity with his bad character. See CRE 404(b); Imwink-elreid[, Uncharged Misconduct Evidence,] § 218 [ (1984) ]. Finally, if the proffered evidence survives the first three parts of the analysis, we must assess whether the probative value of the evidence is substantially outweighed by the danger of unfair prejudice. CRE 403; Carlson,712 P.2d at 1022 .
By way of summary, therefore, we hold that CRE 104(a) is applicable to the resolution of preliminary questions concerning the admissibility of other-crime evidence. Before admitting such evidence, the trial court, on the basis of all the evidence before it, must be satisfied by a preponderance of the evidence that the other crime occurred and that the defendant committed the crime. The Court then must consider whether the other-crime evidence is being offered for a proper purpose and is logically relevant to a material issue in the case, whether the logical relevancy of the evidence is independent of the intermediate inference of the defendant’s bad character, and whether the probative value of the
IV.
It is obvious from our prior discussion that the judgment of the court of appeals must be reversed. The court of appeals erred in ruling that the prosecution, as the proponent of the other-crime evidence, was required to establish by clear and convincing evidence, rather than by a preponderance of the evidence, the occurrence of the other crime and the defendant’s identity as the perpetrator of that crime. In addition, the court of appeals incorrectly held that the trial court was required to determine the admissibility of other-crime evidence by analyzing the evidence related to the other crime separately and independently of other evidence rather than by considering all the evidence in the case.
A review of the record demonstrates that the trial court did not err in admitting the prosecution’s other-crime evidence in this case. In admitting this other-crime evidence, the trial court did not base its ruling on its determination that the jury could reasonably find by a preponderance of the evidence that the conditionally relevant facts were established. Rather, the trial court, before admitting the other-crime evidence, satisfied itself that the prosecution established all preliminary conditions relating to the admissibility of that evidence. Although the trial court erred in utilizing the “clear and convincing” standard of proof in its evidentiary rule, the error in that respect inured to the benefit of the defendant.
Under the preponderance-of-evidence standard, the evidence before the trial court at the time of the court’s evidentiary ruling demonstrated not only that the other crimes occurred but also that the defendant committed each of these other offenses. The evidence also satisfied the four-part relevancy test for the admissibility of other-crime evidence. First, the other-crime evidence related to a material fact in the case — the identity of the defendant as the perpetrator of the murder charged against him. Second, the other-crime evidence was logically relevant to the issue of identity, inasmuch as it had a tendency to make the existence of identity more probable with the evidence than without it. Third, the logical relevancy of the evidence was independent of any inference that the defendant was a person of bad character and thus, inferentially, had committed the crime charged against him in conformity with his bad character.
The logical nexus between the other-crime evidence and the material issue of identification was clearly manifested in the distinctive manner in which the crime charged and the other crimes were committed. In each instance, the defendant was involved with the victim in a personal relationship which was either about to terminate or was substantially deteriorating at the time of the crime. The defendant in each instance had free access to the victim’s residence and was the last person known to have been with the victim prior to the discovery of the victim’s body. Of par
Last, we are satisfied that the trial court did not err in determining that the probative value of the other-crime evidence was not substantially outweighed by the danger of unfair prejudice to the defendant. To be sure, any evidence that strengthens the prosecution’s case carries with it some degree of disadvantage to an accused. This is especially true in the case of other-crime evidence. In the instant case, however, the trial court was clearly cognizant of the risk of prejudice posed by the other-crime evidence and balanced that risk against the probative value of the evidence in ruling that the probative value of the other-crime evidence was not outweighed by the danger of unfair prejudice to the defendant. In light of the obvious significance of the other-crime evidence to the critical issue of identity, we cannot say that the trial court erred in its evidentiary ruling.
The judgment of the court of appeals is reversed, and the judgment of conviction entered by the trial court is hereby reinstated.

. Although Wilson was murdered on July 1, 1982, the defendant was not charged in this case until approximately two years later, when the defendant became implicated in the strangulation death of Jennifer Della Costa, who, like Wilson, was a Winchell’s Donut shop trainee and was murdered under circumstances very similar to those involved in the instant prosecution.

In Huddleston, the Supreme Court recognized the danger of unfair prejudice presented by the admission of other-crime evidence, but went on to conclude that the source of protection against such prejudice did not emanate from the requirement of a preliminary finding of the conditional fact that rendered the proffered evidence relevant, but rather from the following provisions of the Rules of Evidence:
first, from the requirement of Rule 404(b) that the evidence be offered for a proper purpose; second, from the relevancy requirement of Rule 402 — as enforced through Rule 104(b); third, from the assessment the trial court must make under Rule 403 to determine whether the probative value of the similar acts evidence is substantially outweighed by its potential for unfair prejudice ...; and fourth, from Federal Rule of Evidence 105, which provides that the trial court shall, upon request, instruct the jury that the similar acts evidence is to be considered only for the proper purpose for which it was admitted.
