Ohio, Hawaii, Kentucky, Michigan, and Massachusetts no longer apply the felony murder rule. (Abolished)

Arkansas, California, Connecticut, Delaware, Maine, New Jersey, New York, North Dakota, Oregon, and Washington limit the felony murder rule to the actual perpetrators of the homicide.

There are many states currently in the process of changing their felony murder laws, including Florida, Illinois, Maryland, Colorado, and Minnesota. The most recent reform is California’s SB 1437. In September 2019, Governor Brown signed a reform of the law which effectively ended the role of the “natural and probable consequences” doctrine in murder cases. They not only reformed the law, but also made the change retroactive.
