delivered the Opinion of the Court.
We granted certiorari to review the decision of the Colorado Court of Appeals in
People v. Frye,
I.
Because consistency of verdicts is at issue here, we set forth the evidence in some detail.
On the evening of February 25,1991, Ronald S. Frye, a twenty-one-year-old man who had recently moved from Chicago, Illinois, to Denver, Colorado, was arrested for allegedly sexually assaulting a woman in her apartment. He was subsequently charged with first degree burglary, 1 second degree burglary, 2 sexual assault in the first degree, 3 and *561 menacing with a deadly weapon. 4 He was also charged with two counts of mandatory sentencing for a crime of violence. 5 Frye gave notice to the prosecution that he generally denied the charges and intended to assert the affirmative defense of consent to the allegedly illegal acts.
Frye’s jury trial began on August 12,1991, in the Arapahoe County District Court. The first person to testify for the prosecution was the alleged victim. 6 Doe, a twenty-year-old woman, testified that she had moved to the Denver area in November of 1990 from Pueblo, Colorado, where she had been living with her parents. She further testified that she had rented a one bedroom apartment on the third floor of an apartment complex on South Dahlia Street that she shared with a roommate. The living room of the apartment had a large window that looked out onto the walkway in front of the apartment and into the courtyard area of the apartment complex.
Doe testified that on the evening of February 25, 1991, at approximately 8:40 p.m., she was alone at home and engaged in a long-distance telephone conversation in the living room of her apartment when she saw a man, later identified as Ronald S. Frye, walk in front of her apartment window. She waved her hand at Frye, who stopped and waited until she had completed her telephone conversation, a period of approximately fifteen minutes. Doe said that she had motioned to Frye because she was new to Denver and was hoping to meet a friend. She noticed that he had two liquor bottles in his hand and that he set the bottles on the ledge in front of her apartment and watched her until she hung up the telephone and opened the front door.
Doe further testified that after she opened the front door, she and Frye chatted for approximately five minutes. Frye said something to the effect of “You must be awful good looking to have me wait so long,” to which Doe did not respond. Doe then invited Frye into her apartment. Frye set the two liquor bottles on the floor and sat down in a chair near the front door. Doe sat down at the foot of an adjacent pull-out sofa bed 7 and she and Frye shared Frye’s one remaining cigarette.
Doe then turned on her stereo, after which Frye moved from the chair in which he had been sitting and sat down next to Doe on the sofa-bed. The two continued to converse and Frye attempted to put his arm around Doe, but she again stood up to adjust the music on her stereo. Frye stated that he was worried about being seen by some gang members and went to the window and closed the curtains. Both Doe and Frye sat back down on the sofa-bed and the two talked for a while longer. Frye indicated that he was intending to obtain some marihuana later that night, and Doe said she would be interested in some.
Although Doe could not remember precisely how many times she rose from the sofabed, she testified that while sitting next to Frye, he leaned over and tried to kiss her and at the same time “just rolled himself’ on top of her. She further testified that Frye reached for something at his back with his right arm, pulled out a pistol, and held it to her left temple. Frye ordered her to remove her pants, underpants, and shoes, and then raped her while pointing the gun at her left temple.
Doe further testified that after a period of time, she yelled for help but that no one heard her. Frye told her to shut up. Doe stated that over the next three hours, Frye repeatedly raped her vaginally, anally, and orally, in various parts of the apartment, including on the kitchen counter and the living room floor and in the bathroom. Doe stated that throughout the ordeal, Frye kept the gun pointed at her head.
*562 Doe testified that, at one point, while she was being sexually assaulted on the floor of the living room next to where the stereo was located, she reached up and turned the volume of the music on to its fullest extent, hoping to trigger a noise complaint and arouse the attention of the apartment complex’s security guard. Sometime thereafter, Doe heard a knocking on the door and thought that it was the security guard. She asked Frye if she could turn down the volume on the stereo and he said “no.” She then asked him if she could answer the door. Frye asked whether she was expecting anyone, to which she replied “no.” Frye refused to allow Doe to answer the door and continued sexually assaulting her on the sofa-bed.
Sometime later, Doe and Frye again heard knocking on the door. Doe testified that she thought it was the police authorities in response to the continued loud music from her stereo. When the knocking persisted, Frye ordered Doe into the bathroom, where he forced her to perform oral sex while pointing the gun at her head. He asked her if she had a boyfriend and she replied falsely that she did.
Doe stated that she finally convinced Frye that she had to urinate and he left the bathroom and got dressed. He then returned to the bathroom, wearing his clothes, and began fixing his hair. Doe did not see the gun at that time. Frye told Doe something to the effect of “I don’t want to hurt nobody, but I will if I have to protect myself.” While Doe was seated naked on the toilet, several police officers removed the screen from the apartment window, drew back the curtain, and shined a flashlight inside. The officers asked Frye if everything was all right. While Frye was speaking to the officers and stating that everything was fine, Doe was gesturing to the officers and mouthed the word “help” in a manner so that Frye could not see or hear her. The police officers asked Frye to open the front door of the apartment and Doe ran into the bedroom. After entering the apartment, one of the police officers went into the bedroom where Doe was waiting. Doe informed the officer that Frye had just raped her and that he was armed with a gun.
Steven Poindexter, the security guard at the apartment complex where Doe resided, was the next person to testify for the prosecution. He stated that on the night in question, he had heard loud music from a stereo emanating from Doe’s apartment. He testified that he first knocked on the door at 11:00 p.m., received no answer, and then returned at 11:30 p.m. and knocked again. When no one responded the second time, Poindexter returned to his office and called the police because he thought someone was home and that something might be wrong.
Poindexter returned to Doe’s apartment with three police officers at approximately midnight. One of the officers knocked on the door with his flashlight. When no one responded, the officers asked Poindexter for permission to remove the screen from the apartment window, to which he agreed. According to Poindexter, when the officers removed the screen and looked inside with the aid of the flashlight, they saw Doe sitting naked on the toilet and Frye putting on his shirt. Poindexter testified that Doe appeared to be extremely upset, that she had her head down, and that she was crying. He later saw her being escorted out of the apartment complex by paramedics, staggering as though she was hurt in some way and crying.
James Dillon, of the Glendale Police Department and one of the officers who responded to Poindexter’s call, also testified for the prosecution. Dillon stated that after they entered the apartment, he saw Doe emerging from the bathroom and entering the living room — hunched over in an attempt to cover herself. Dillon testified that Doe waved her arms at him to attract his attention and that she mouthed the word “help.” Dillon stated that Doe appeared scared and that she was shaking; he followed her into the bedroom where Doe tried to speak but her voice was inaudible. He further testified that Doe continued to back into the bedroom, all the way into the back of the closet before she was able to say that she had just been raped. Doe told Dillon that she did not know Frye and that he was armed. Dillon returned to the living room of the apartment where he conducted a “pat down” of Frye for weapons. Dillon did not find a weapon, and *563 one of the other officers, Paul Bloomfield, returned to the bedroom to speak to Doe while Dillon waited with Frye. When Bloomfield returned, Dillon conducted another pat down search of Frye but again did not find a weapon. He then handcuffed Frye and took him to the Glendale Police Department.
Several other Glendale law enforcement officials arrived at Doe’s apartment to assist Officer Bloomfield. One officer found a gun hidden between the cushions of the chair near the front door where Frye had sat upon entering the apartment. The officers then collected other items from the apartment that they thought might have some evidentia-ry value and waited for the paramedics to arrive to take Doe to the hospital.
Doe was taken to University Hospital in Denver where she was examined by medical professionals. Relevant samples were collected from Doe and given to a Glendale police officer who was waiting at the hospital. Hair, blood, and saliva samples were taken from Frye while he was in custody at the Glendale Police Department. The prosecution presented evidence of the results of the various tests and of the examination of the weapon found at the scene.
The final witness to testify at the trial was Detective Thomas Matthew Bruce of the Glendale Police Department. Bruce testified that on the evening of Frye’s arrest, he and two other officers interviewed Frye while he was in custody at the Glendale Police Department. After Frye was advised of his right not to answer questions while in police custody, he explained that he had passed by Doe’s apartment window when he saw her talking on the telephone. Frye stated that Doe gestured to him, as if to say “wait a minute,” which he did. Frye further explained that after opening her apartment door and chatting with him, Doe let him into the apartment, where the two proceeded to have consensual sexual intercourse. When questioned about his use of the gun, Frye initially denied that Doe had ever seen it. When told by Bruce that Doe could identify and describe the gun in some detail, Frye then stated that Doe may have seen the gun in his back pants pocket and that he had removed the gun from his rear pocket when he first heard someone knocking on the door. Detective Bruce also tested Frye’s blood alcohol level and found that it was .081 at 2:00 a.m.
The ease was submitted to the jury, and the jurors were instructed that Frye had been charged with committing the crimes of first degree burglary, second degree burglary, sexual assault in the first degree, and menacing. The court delivered the instructions to the jury and in instruction number 14, concerning first degree sexual assault, described the offense as follows:
1. That the defendant,
2. in the State of Colorado, at or about the date and place charged,
3. knowingly,
4. inflicted sexual penetration on a person, and
5. caused submission of that person,
6. through the actual application of physical force, physical violence,
or
7.(a) by threat of imminent death, serious bodily injury, extreme pain, or kidnapping to be inflicted upon anyone, and
(b) the person submitting believed the defendant had the present ability to execute the threat,
8.without the affirmative defense [of consent].
The trial court also instructed the jury by instruction number 15 as to the elements of menacing with a deadly weapon:
1. That the defendant,
2. in the State of Colorado, at or about the date and place charged,
3. by threat or physical action,
4. knowingly placed or attempted to place another person in fear of imminent serious bodily injury,
5. by the use of a deadly weapon. 8
*564 The trial court further explained that should the jury find Frye not guilty beyond a reasonable doubt of any offense charged, that he may be found guilty of any lesser included offense. The trial court in instruction number 16 explained that the offense of first degree sexual assault includes the lesser offense of second degree sexual assault, and described the offense as follows:
1. [TJhat the defendant,
2. in the State of Colorado, at or about the date and place charged,
3. knowingly inflicted sexual penetration on a person, and
4. caused submission of that person
5. by any means of sufficient consequence,
6. reasonably calculated to cause submission against that person’s will.
7. without the affirmative defense [of consent].
During deliberations, the jury sent a number of written questions to the trial court judge, requesting clarification of several of the above-described jury instructions. The first question was as follows:
Jury Question # 1
Can we conclude, in terms of the sexual assault charge, that concent [sic] may initially be given, and then later may be withdrawn.
Can we conclude that when concent [sic] is withdrawn a crime was comitted [sic]. Can we conclude that if concent [sic] is given for vaginal sex but not for anal sex, that the commission of anal sex constituted a sexual assault, as charged.
The trial court provided the jury with the following answer:
You have received all of the instructions of law that you may properly use to decide this ease. No further instructions as to questions you have raised may be given.
The jury also requested copies of Frye’s statement given to Detective Bruce on the night of the alleged assault and copies of Doe’s medical reports from University Hospital, or the court transcripts regarding the medical reports and Detective Bruce’s testimony. The trial court responded by stating in writing to the jury that “[y]ou have received all of the evidence that you may properly use to decide this case. No further evidence may be submitted to you.”
On returning to the courtroom after deliberations, the jury returned verdict forms that revealed that the jurors could not reach agreement as to the first or second degree burglary charges. However, the jury found Frye guilty of sexual assault in the second degree and menacing with a deadly weapon. The jury inferentially found the defendant not guilty of first degree sexual assault. The trial court subsequently sentenced Frye to sixteen years in the Department of Corrections for second degree sexual assault and eight years for menacing with a deadly weapon, the sentences to run consecutively.
Frye appealed the judgment of conviction to the court of appeals where he challenged the jury’s verdict finding him guilty of menacing with a deadly weapon. Frye maintained that the verdict of guilty as to that charge was inconsistent with the verdict acquitting him of first degree sexual assault. The court of appeals majority noted, as an initial matter, that the appropriate standard for reviewing a claim of inconsistent verdicts was that set forth in
Robles v. People,
*565
In response to Frye’s argument that his conviction for menacing -with a deadly weapon was inconsistent with his acquittal of first degree sexual assault, the court of appeals determined that according to
Robles,
the evidence supporting the felony menacing charge must be different than that relied on by the jury for the sexual assault conviction.
Id.
The court of appeals concluded that such was the case here and that the two convictions therefore were not inconsistent.
Frye,
Judge Tursi concurred in part and dissented in part. Judge Tursi agreed with the majority that the controlling standard was that articulated in
Robles,
but concluded that there was no independent evidence to sustain Frye’s conviction for menacing with a deadly weapon.
Frye,
The prosecution sought certiorari review of that part of the court of appeals’ decision holding that Robles is the controlling standard in inconsistent verdict eases, and Frye cross-petitioned for certiorari to review that portion of the decision holding that the two verdicts were not inconsistent. We granted certiorari on the following two issues, the first of which is based on the prosecution’s petition and the second on Frye’s cross-petition:
1. Whether the court of appeals erred in declining to follow Crane v. People,91 Colo. 21 ,11 P.2d 567 (1932), and its progeny, and holding instead that under Robles v. People, [160] Colo. 297,417 P.2d 232 (1966), the defendant could attack his conviction on one count on the ground that it is inconsistent with a verdict of acquittal on another count.
2. Whether the court of appeals erred in holding that the jury did not render inconsistent verdicts based on the same evidence, when it acquitted the defendant of first degree sexual assault despite convicting him of felony menacing.
II.
A.
Frye maintains that the jury’s verdict of guilty on the charge of menacing with a deadly weapon should be vacated because it is inconsistent with the verdict acquitting him of first degree sexual assault. After reviewing the record, we conclude that only by a most strained analysis could the two guilty verdicts be held to be consistent.
If the jury had believed that Frye used a gun to cause Doe’s submission, it would logically have found him guilty of first degree sexual assault. See jury instruction no. 14, pars. 6 and 7, supra at p. 10. Therefore, a verdict of not guilty of first degree sexual assault but guilty of second degree sexual assault suggests that the jury found that Frye did not use a gun to cause Doe to submit. Such a finding would be at odds with the guilty verdict for menacing with a deadly weapon because there is no evidence that Frye used the gun other than in the course of the sexual assault.
When Doe testified at trial, she stated that Frye held a gun to her head throughout the duration of the sexual assault, indicating that the gun was not used for any other reason or at any other time than during the sexual assault. The evidence also revealed that the police authorities found a gun not belonging to Doe at Doe’s apartment shortly after the sexual assault.
For reasons unknown to us, the jury chose not to believe Doe’s testimony that Frye used a gun to cause her submission to the sexual assault. However, in the face of irrefutable evidence that a gun was found at the apartment, the jury convicted Frye of menacing with a deadly weapon. The court of *566 appeals’ conclusion that the two guilty verdicts were not inconsistent is unpersuasive and results in the kind of speculation into a jury’s thought processes that courts generally eschew. Thus, although in the past we have made every effort to find consistency in jury verdicts, such an effort could be rewarded here only if we were to accept as an explanation the highly unconvincing and artificial possibility that the jury believed the menacing occurred only after Frye returned to the bathroom fully clothed and with no gun visible to Doe after the sexual assault had terminated. The menacing would have been predicated entirely on Frye’s statement that “I don’t want to hurt nobody, but I will if I have to protect myself,” taken together with evidence that Doe knew Frye had access to a gun. Therefore, to find consistency in the verdicts, we would have to conclude that the jury disbelieved Doe’s repeated and consistent testimony that Frye held a gun to her head during the sexual assault but believed that by the quoted statement, Frye placed or attempted to place Doe in fear of imminent serious bodily injury by use of the gun which was not visible to her at the time. We reject such an implausible explanation and conclude that the verdicts are indeed inconsistent.
B.
We thus find ourselves directly confronted with the issue of the appropriate standard of review to be applied in inconsistent verdict cases. Frye contends that this court should adhere to the principle, enunciated in
Robles v. People,
A review of previous decisions of this court is necessary to describe the differing approaches we have taken in addressing the issue of inconsistent jury verdicts.
9
In
Crane v. People,
The
Crane
rule was applied in a number of subsequent decisions that similarly gave deference to the jury’s fact finding authority and recognized that inconsistent verdicts may stem from the jury’s leniency toward the defendant.
Elstun v. People,
However, in
Robles v. People,
Although the holding in
Robles
was limited to conspiracies established solely by evidence of commission of the substantive offense, subsequent court of appeals decisions have relied on
Robles
as support for the more general proposition that the test for inconsistent verdicts is whether the jury had to rely on the very same evidence in producing two apparently inconsistent verdicts.
People v. Atkins,
In every reported decision since
Robles,
we have determined that the challenged verdicts were not inconsistent. As a result, we have not been confronted with the need to resolve the conflict between
Robles
and the
Crane
line of cases. For example, in
Maisel v. People,
In
People v. Mayfield,
The defendant here has asked this court to reaffirm the rule set forth in
Robles,
as it has been refined in subsequent cases, prohibiting inconsistent acquittal and guilty verdicts that are based on identical evidence. It is noteworthy that subsequent to our decision in
Robles,
the United States Supreme Court reaffirmed the federal rule that if a defendant is convicted on some counts but acquitted on others, the convictions will generally be upheld, despite their rational incompatibility with the acquittals.
United States v. Powell,
In Powell, the jury had acquitted the defendant of the predicate felonies involving the distribution or conspiracy to distribute illegal drugs but had convicted her of the compound offense of using the telephone to facilitate the commission of those felonies. In reversing the court of appeals’ decision that the acquittal on a predicate felony necessarily indicated that there was insufficient evidence to support a telephone facilitation conviction, the United States Supreme Court explained that
where truly inconsistent verdicts have been reached, ‘[t]he most that can be said ... is that the verdict shows that either in the acquittal or the conviction the jury did not speak their real conclusions, but that does not show that they were not convinced of the defendant’s guilt.’ Dunn, [284 U.S.] at 393, [52 S.Ct. at 190 ], The *569 rule that the defendant may not upset such a verdict embodies a prudent acknowledgement of a number of factors. First, as the above quote suggests, inconsistent verdicts — even verdicts that acquit on a predicate offense while convicting on the compound offense — should not necessarily be interpreted as a windfall to the Government at the defendant’s expense. It is equally possible that the jury, convinced of guilt, properly reached its conclusion on the compound offense, and then through mistake, compromise, or lenity, arrived at an inconsistent conclusion on the lesser offense.
Powell,
The court also declined the invitation to establish a rule that would allow criminal defendants to challenge inconsistent verdicts on the ground that the verdict was not the product of lenity, but of some error that worked against them: “Such an individualized assessment of the reason for the inconsistency would be based either on pure speculation, or would require inquiries into the jury’s deliberations that courts generally will not undertake.”
Powell,
Sufficiency-of-the-evidence review involves assessment by the courts of whether the evidence adduced at trial could support any rational determination of guilt beyond a reasonable doubt. This review should be independent of the jury’s determination that evidence on another count was insufficient. The Government must convince the jury with its proof, and must also satisfy the courts that given this proof the jury could rationally have reached a verdict of guilt beyond a reasonable doubt.
Id., (citations omitted and emphasis added). Thus, sufficiency of the evidence review and inconsistent verdict challenges have two different focuses, although they both theoretically protect against jury irrationality or error.
The court in
Powell
refused to create an exception to the
Dunn
rule where the jury acquits a defendant of a predicate felony but convicts on the compound felony, holding that consistency in verdicts of guilt and acquittal are not necessary and that “the best course to take is simply to insulate jury verdicts from review [on the grounds of inconsistency].”
Powell,
*570
Numerous state courts have also adopted the
Dunn
rule that consistency among verdicts on several counts of an indictment or information is unnecessary where a defendant is convicted on one or more counts but acquitted on others. As long as sufficient evidence supports each of the guilty verdicts, state courts generally have upheld such convictions irrespective of their rational incompatibility with the acquittals.
Hammond v. State,
We conclude that the court of appeals erred in declining to follow
Crane v. People,
Under our criminal jurisprudence we have surrounded one who is charged with a criminal offense with constitutional safeguards against the exercise of arbitrary power by courts, one of which is trial by *571 jury. There are a number of others, all necessary to protect the liberties of men. To retain the right of trial by jury it is necessary that the system remain practicable and workable, and that we do not erect barriers which are not predicated upon sound interpretations of constitutional principles and inconsistent with the practical means used by a jury in reaching its conclusions.
Elstun,
III.
We conclude that consistency in verdicts is unnecessary in circumstances such as those presented here, thus reaffirming this court’s decision in
Crane v. People,

.Doe testified that the sofa-bed was unfolded at the time Frye entered her apartment. She stated that it was kept unfolded all of the time because that was where she slept regularly and she was “too lazy to put it up" after sleeping in it.
. The trial court also instructed the jury on the offense of menacing without a deadly weapon, the elements of which are identical to menacing with a deadly weapon except that the former offense does not involve the use of such a weapon.
. " 'Inconsistency' is generally understood to mean some logical impossibility or improbability implicit in the jury’s findings as to the various counts of the indictment or information. It may arise from factual considerations, as where the jury finds under one count that defendant did not possess illegal liquor but under another that he sold it, or from legal considerations, as where multiple verdicts of guilty are returned under counts charging both the theft and receipt of the same stolen property.” W.E. Shipley, Annot.,
Inconsistency of Criminal Verdict as Between Different Counts of Indictment or Information,
This case involves the 'factual inconsistency' between the jury's verdict convicting Frye of menacing with a deadly weapon and its verdict acquitting him of first degree sexual assault.
.The defendant in
Dunn
was charged in a three count indictment with violating federal liquor laws. The defendant was convicted of maintaining a common nuisance by keeping intoxicating liquor for sale at a specified place, but acquitted of the unlawful possession and unlawful sale of such liquor. The court in
Dunn
rejected the defendant’s claim that his conviction should be discharged because the verdicts were inconsistent, holding that “[cjonsistency in the verdict is not necessary. Each count in an indictment is regarded as if it was a separate indictment.”
Dunn,
The
Dunn
rule was elaborated on in
United States v. Dotterweich,
. The dissent in
Robles
noted that the inconsistent verdicts issue decided by the majority was not briefed or argued by the parties.
Robles,
. In 1971, the “Robles rule” was codified by the General Assembly and now appears at § 18-2-206(2), 8B C.R.S. (1986):
A person may not be convicted of conspiracy to commit an offense if he is acquitted of the offense which is the object of the conspiracy where the sole evidence of conspiracy is the evidence establishing the commission of the offense which is the object of the conspiracy.
. The Colorado Court of Appeals incorrectly applied the exclusion explained in footnote eight to distinguish
Powell
from the present case. Footnote eight refers to those cases where a jury has returned verdicts convicting a defendant of two or more crimes, where the existence of an element of one of the crimes negates the existence of a necessary element of the other crime. In such situations, courts are generally uniform in their agreement that the verdicts are legally and logically inconsistent and should not be sustained.
Thomas v. United States,
In the present case, Frye’s convictions for second degree sexual assault and felony menacing are not legally or logically incompatible because each offense consists of separate and distinct elements that are not mutually exclusive. Thus, contrary to the court of appeals' assertion, the question in this case does not involve the legal incompatibility of the two guilty verdicts, but rather whether the two verdicts are factually inconsistent.
. As previously noted,
see supra
at 24-25, each guilty verdict must be based on sufficient evidence. Sufficiency of the evidence issues are not to be confused with inconsistent verdict issues.
