Who is guilty of felony murder in these scenarios?

[Person Man]

I would definitely think B. I don't really see it any connection to the rapist's death with C and D's felonies. In many states, it could be A. Is a getaway driver for a robbery where someone is killed guilty of felony murder? You could claim that A and B's conspiracy didn't involve them conspiring to kill the trafficker but they were all conspirators in a felony. Some states make responsible conspirators of a felony in the death of their coconspirators.
