Aрpellant, Edwin Ike Mares, appeals the judgment and sentence of the district court convicting him of felony murder, aggravated burglary, and conspiracy to commit burglary. Mares bases his appeal on what he perceives to be the unfair application of the felony murder rule as it currently exists in Wyoming, advocating that we judicially modify the statute. In the alternative, he argues that the sentence he received was constitutionally infirm under a proportionality analysis. We vacate Mares’ sentence for the underlying felony of aggravated burglary. In all other respects, the district court’s order of judgment and sentence is affirmed.
Mares presents the following issues for our review:
I. Whether the Appellant should have been convicted under the felony murder rule as he did not commit, cause, solicit оr aid in the homicide; he had no reason to believe that a cohort would engage in conduct likely to cause serious bodily injury or death; he was not armed with a deadly weapon and he had no reason to believe one of his companions was armed with a deadly weapon.
II. Whether the Wyoming felony-murder doctrine denies the Appellant his due process rights pursuant to the United States and Wyoming Constitutions.
III.Did the trial court err when it imposed a sentence which was disproportionate to the sentences received by the co-defendants in this case, as well as other criminals convicted of the same offense in Wyoming?
The State phrases the issues as follows:
I. Was Appellant properly convicted of the crime of felony murder?
II. Are the sentences Appellant received unconstitutionally disproportionate?
FACTS
On November 30, 1993, Marie Bressler celebrated her 81st birthday by going to dinner with her two granddaughters. Bres-sler’s long-time friend, 76-year-old Velma Filener, was visiting Bressler at the time but did not accompany the Bressler party to dinner. Bressler and her granddaughters left the house around 6:15 p.m. Approximately two hours later, Bressler returned to her unlocked and well-lit homе and found the body of Filener lying between the laundry room and kitchen. Filener had been stabbed seventeen times, and her body had been dragged from a hallway near the entry of the home to the laundry room. The home obviously had been burglarized. The county coroner estimated Filener’s time of death to be between 7:30 and 8:15 p.m.
Five months later, 16-year-old Heather Carrillo informed pоlice and counselors at the Wyoming Girls’ School that she was involved in the Bressler burglary. At Mares’ trial, Carrillo testified that on November 30, 1993, she stole her mother’s car and drove Victor Madrid to Bressler’s home, where they met Mares and Christine Sievers. After waiting for a car to leave the residence, the four teenagers entered the residence wearing rubber gloves provided by Madrid. Once inside, the teens split up and went to different rooms. Upon hearing a female voice confront Madrid, Carrillo became scared and left the house. Carrillo testified that as she waited in the car, Mares came out of the house, followed by Sievers, and finally Madrid. Madrid was covered in blood.
Two other witnesses for the State testified that Mares told them he had been in the *727 Bresslеr home when Madrid stabbed Filener. Although Mares did not testify at his trial, during an interview with two detectives from the Casper Police Department on June 2, 1994, he confessed to participating in the crime. The detectives testified at Mares’ trial. Mares told the detectives that he, Victor Madrid, Christine Sievers, and an unknown female (later identified as Carrillo) entered the Bressler residence with the intеnt of “doing a little burglary.” Mares stated that he was in a back bedroom of the house when he heard what sounded like a woman falling down stairs and screaming. He came out of the bedroom and witnessed Madrid stabbing the victim. Carrillo immediately ran out of the house. Mares and Sievers implored Madrid to leave, but he refused and told them to “just go,” and they left the house through the front door. Madrid followed them outside, and then went back inside with Sievers. Mares told the detectives that he returned to the car where Carrillo was waiting. Shortly thereafter, Madrid and Sievers returned to the car and the four left. Mares also told the detectives that Madrid stabbed Filener with a “butterfly knife” which Mares had given Madrid a few days earlier.
After a ten-day trial, the jury found Mares guilty of felony murder, aggravated burglary, аnd conspiracy to commit burglary for his part in the burglary of the Bressler home and the murder of Filener. He received a sentence of life imprisonment for the felony murder conviction, a concurrent term of 20 to 25 years in prison for the aggravated burglary conviction, and a consecutive term of 4 to 5 years in prison for conspiracy. He timely appeals the judgment аnd sentence.
DISCUSSION
I. Affirmative Defense
Mares argues that because the stabbing was a purely independent act of a co-felon, the rigid application of the felony murder doctrine, resulting in a life sentence, is unduly harsh. Mares advocates we adopt an affirmative defense to felony murder which would apply if a defendant satisfies a list of conditions refuting the defendant’s culpability for the killing. Sеveral jurisdictions have statutorily created a no-culpability-as-to-the-homicide defense, with the most common conditions being that the defendant 1) did not commit the homicidal act or in any way cause, solicit, or aid the commission thereof, 2) had no reason to believe that any other participant would engage in conduct likely to cause death or serious bodily injury, 3) was not armed with a deadly weapon, and 4) had no reason to believe that any other participant was armed with such a weapon. Paul H. Robinson, 1 CRIMINAL Law Defenses § 104, at 504-05 (1984); Wayne R. LaFave & Austin W. Scott, Jr., CRIMINAL Law § 7.5(c), at 624 (2nd ed.1986).
The legislature abolished common law crimes in Wyoming, but chose to retain common law defenses unless provided otherwise by statute. W.S. 6-1-102 (1988). Therefore, our first inquiry is whether the defense proposed by Mares is recognized in Wyoming by statute or judicial decision.
Bouwkamp v. State,
Two Wyoming felony murder cases addressed the issue of a defendant’s individual culpability, both in the context of the death penalty. In
Engberg v. State,
Further, Mares does not provide, nor does our own research reveal, any authority that the proffered defense is a recognized common-law defense in any other jurisdiction. The jurisdictions that have created a no-culpability-as-to-the-homicide defense for felony murder have done so legislatively, not judicially. See Robinson, supra, at 507 & 85 (Supp.1997), n. 8 (listing statutes which provide no-culpability defense).
The felony murder rule is the subject of much criticism for its potential harshness, for instance in the circumstance where the killing is an independent act of a co-felon, as in Mares’ case.

The Felony-Murder Rule: A Doctrine at Constitutional Crossroads,
70 CORNELL L.Rev. 446, 446-48 (1985). Adopting an affirmative defense is but one of many mechanisms that other jurisdictions have utilized to mitigate the potential harshness of the rule. For example, the rule has been limited by permitting its use only as to certain types of felonies, by strictly interpreting the requirement of proximate or legal cause, by narrowly construing the time period during which the felony is committed, by downgrading the offense to a lesser degree crime, and by requiring a
mens rea
of malice. La-Fave & Scott,

People v. Aaron,
II. Mens Rea
At the time of the offense, Wyoming’s first degree murder statute provided:
(a) Whoever purposely and with premeditated malice, or in the perpetration of, or attempt to perpetrate, any sexual assault, arson, robbery, burglary, escape, resisting arrest or kidnapping, kills any human being is guilty of murder in the first degree.
W.S. 6-2-101(a) (Supp.1993)
1
Under this provision, when a killing arises out of one of the enumerated felonies, it makes no difference whether or not there was an intent to kill.
Bouwkamp,
Mares’ due process challenge appears to be based on
Sandstrom v. Montana,
Mares directs us to
State v. Ortega,
in which the New Mexico Supreme Court, relying in part on
Sandstrom,
held that New Mexico’s felony murder statute requires proof that the defendant intended to kill or was knowingly heedless that his or hеr acts created a strong probability of death or great bodily harm.
Ortega,
A. Murder in the first degree is the killing of one human being by another without lawful justification or excuse, by any of the means with which death may be caused: * * *
(2) in the commission of or attempt to commit any felony * * *.
N.M. Stat. Ann. § 30-2-l(A)(2) (Miehie 1984). We find the dissent in Ortega persuasive and more in line with our prеvious holdings in Wyoming. The dissent considered Sandstrom inapposite because the New Mexico statute does not require an intent to kill where a killing has been committed during a felony. Id. at 1218-19 (Baca, J., concurring in part, dissenting in part). In Osborn v. State, we pointed out that viewing the commission of the statutory felony as the legal equivalent of the malice and premeditation required for first degree murder is a legal fiction that is unnecessary under our statute:
[T]he Wyoming Statute, § 6 — 4—10Í * * *, does not relate the killing of a human being in the perpetration of robbery (or the other crimes listed) to “purposely and with premeditated malice,” but separated that clause with an “or.” The legislature has thus merely labeled the latter crime as first degree murder because it is considered to be of equal wickedness justifying the ultimate penalty.
Osborn,
Mares also directs us to
People v. Aaron,
There is no question the legislature has the authority to revise the current statute to include a
mens rea
of malice for killings ocсurring during the perpetration of a felony. The legislature has the exclusive power to determine and declare what acts shall constitute crimes.
Billis v. State,
III. Sentence
A defendant convicted of first degree murder in Wyoming shall be sentenced to life imprisonment or death, pursuant to W.S. 6-2-101(b) (Supp.1993). Mares received a sentence of life imprisonment for the felony murder conviction. He also received a concurrent term of 20 to 25 years in prison for the aggravatеd burglary conviction and a consecutive term of 4 to 5 years in prison for conspiracy, both of the latter sentences within the parameters set by the legislature for those crimes. W.S. 6-3-301(a), (b) (1988); W.S. 6-1-304 (1988). Mares contends that the court abused its discretion and violated his constitutional rights by treating him more harshly than his codefendants as well as other persons in Wyoming who have been convicted of felony murder where the underlying felony is burglary.
At the outset, the State concedes, and we agree, that the sentence imposed for the aggravated burglary conviction, which was the underlying felony for purposes of the felony murder conviction, was improper. In Wyoming, multiple punishments for felony murder and the underlying felony are impermissible and such a sentence is error.
Roderick v. State,
Remaining for our consideration are the life sentence for the felony murder conviction and the prison term of 4 to 5 years for conspiracy to commit burglary. In Wyoming, a life sentence for first degree murder equates to a life sentence without eligibility for parole.
See
W.S. 7-13-402 (1995);
Weldon v. State,
In sum, a court’s proportionality analysis under the Eighth Amendment should be guided by objective criteria, including (i) the gravity of the offense and the harshness of the penalty; (ii) the sentences imposed on other criminals in the sаme jurisdiction; and (iii) the sentences imposed for commission of the same crime in other jurisdictions.
We do not undertake a lengthy analysis under all three of the
Solem
criteria except in cases where a comparison of the crime with the sentence gives rise to an inference of gross disproportionality.
Smith v. State,
Mares’ primary contention is that the relative length of his sentence is extreme
*731
when compared to the gravity of the offense, which he describes as “merely [] involvement in a simple burglary.” The offenses for which Mares was convicted resulted in the death of another human being. This cоurt has previously rejected the argument that the death penalty is disproportionate to the crime of murder committed in the course of a robbery.
Osborn,
Mares’ challenge is aimed, at leаst in part, at the disparity in charging the participants in this crime. Charging decisions fall within the discretion of the prosecuting attorney,
Billis v. State,
Mares’ life sentence for felony murder and the consecutive sentence of 4 to 5 years for aggravated burglary stand as imposed.
CONCLUSION
We decline to judicially modify the felony murder rule in Wyoming by adopting an affirmative defense or establishing a mens rea of malice. We vacate the sentence of 20 to 25 years for aggravated burglary and affirm the life sentence for felony murder and the 4 to 5 year sentence for conspiracy to commit burglary. Affirmed as modified.
