North Carolina has a felony-murder doctrine. That means you do not have to intend to kill someone in order to be charged with murder, if the death occurred during the course of committing a felony (see possession of marijuana and FELONY fleeing to elude arrest charges above). If you rob someone of their wallet, and during the robbery that person has a heart attack and dies, you can be charged with murder in NC. At the very least the suspect should face a manslaughter charge.
