Johnson was an accomplice, but I think it unlikely he has liability for felony murder. The theft was not a felony, not sure about the assault. Whether the theft was over at the time of the encounter of the officer would be an issue as well. There are legions of cases on that issue that are too detailed to get into here.
How can one label it a "felony" murder when the theft had not yet taken place? Does the robber have to have the property in hand in order for it to be valued to see if it meets the felony threshold? Does it matter if he had grabbed a $100 watch vs. a $1,000 necklace?

It has been reported that a police report said that Wilson was responding to a police dispatch of a suspect in a robbery.
But later in the day, it has been reported that police chief Jackson said that Wilson did not know that the teen was a suspect in the robbery.
