The felony murder rule allows prosecutors to charge someone with murder, and seek life sentences, even when that person did not kill anyone. Under this doctrine, anyone involved in a felony that results in a death faces murder liability, regardless of intent or direct participation in the killing.

The Sentencing Project released research showing that 39 states retain versions of this rule. Only Hawaii and Kentucky have abolished it entirely. The consequences are stark. Defendants convicted under felony murder provisions can receive life sentences without parole, even if they played a minor role in the underlying crime or had no knowledge that violence would occur.

The rule originated in English common law centuries ago. Federal courts and nearly every state court still apply it today, creating disparate outcomes based on geography. A person who drives a getaway car during a robbery that results in an unintended killing faces the same potential sentence as the person who pulled the trigger.

Advocates argue the rule punishes people disproportionately. Someone present during a burglary could face murder charges if a homeowner dies from a heart attack triggered by the intrusion. A teenager involved in a street fight where an acquaintance dies could receive life without parole. The rule requires no proof that the defendant intended the death or even knew it was likely.

Legal scholars and criminal justice reformers describe the felony murder doctrine as archaic and unjust. Reform movements have gained traction in some states. California narrowed its rule in 2018, limiting liability to killings the defendant knew were reasonably foreseeable. Several other states have proposed similar restrictions.

The Sentencing Project's analysis underscores a broader debate about criminal culpability and proportionality in sentencing. Prosecutors defend the rule as necessary to deter participation in dangerous felonies. Defense attorneys contend it violates basic principles of fairness by holding people accountable for deaths they did not cause
