This is incorrect. Chavin is charged with felony murder, which is when a death is the result of another felony (in this case, 2nd degree assault). All the state has to prove is the assault charge (that he intentionally took action, that action was not a justified use of force, and that the action caused harm), and that his actions were a significant cause of death. They don't have to prove intent to kill or that a reasonable person would realize it would cause death. Only that he assaulted Floyd, and that his actions did cause (not did exclusively cause) death
