Steve, in desperate need of money, decided to hold up a local convenience store. Determined not to harm anyone, he carried a toy gun that resembled a real gun. In the store, he pointed the toy gun at the clerk and demanded money. A customer who entered the store and saw the robbery in progress pulled his own gun and fired at Steve. The bullet missed Steve but struck and killed the clerk. Steve was charged with felony murder. His best argument for being found NOT guilty is that he 
did not intend to kill. did not commit the robbery because he never acquired any money from the clerk. did not intend to create any risk of harm. is not responsible for the acts of the customer.
