Common questions
Frequently Asked
4
Does the felony-murder rule require proof that the defendant intended to kill the victim?+
No. The rule treats the defendant's intent to commit the underlying felony as supplying the implied malice needed for murder. A killing during the felony therefore supports a murder conviction even without any separate intent to cause death.
Supporting sources
What mental state satisfies the malice element under the felony-murder rule?+
An intent to commit the predicate felony itself supplies the required implied malice. The rule therefore converts an unintentional killing during the felony into murder without needing proof of express malice or other forms of implied malice such as intent to inflict great bodily injury.
Supporting sources
Can a defendant be convicted of murder under the felony-murder rule when the death results from an act that was not inherently dangerous?+
Yes in jurisdictions that apply the rule to any felony.
Supporting sources
How does the felony-murder rule differ from the misdemeanor-manslaughter rule?+
The felony-murder rule elevates an unintentional killing during a felony to murder by supplying implied malice. The misdemeanor-manslaughter rule treats an unintentional killing during a misdemeanor or non-covered felony as involuntary manslaughter rather than murder.
