How the rule works
Under the felony murder rule, a death that occurs during certain serious felonies, or during flight from them, can be charged as murder against the participants even without an intent to kill. New York's law names the specific felonies that qualify. In New York, the person who died must be someone other than one of the participants. The prosecution still has to prove the underlying felony, and it has to connect the death to that felony rather than to some unrelated event. Felony murder is also a state-by-state matter, and the list of qualifying felonies is not the same everywhere.
Limits and defenses
New York provides a narrow affirmative defense for some participants who did not cause the death, and its conditions are demanding. Several states have narrowed felony murder in recent years, for example by requiring that a participant played a major role and acted with reckless indifference to human life. The rules differ enough across jurisdictions that the precise statute in the charging document needs to be read closely. An affirmative defense also generally has to be raised and supported by the defense, which shapes how the case is prepared from the start.
Where the defense usually focuses
Common questions include whether the underlying felony was actually committed or attempted, whether the death happened in the course of it or during flight, and what role each person played. These cases often rely on the testimony of someone else who was charged and is cooperating, and that testimony deserves careful scrutiny. Phone location data, video, and jail calls frequently appear in discovery. If you are a family member, the most useful thing you can do early is help us reach the person charged and avoid discussing the facts on monitored lines.
