Ralph ordered all the persons in the bank to lie on the floor. When some were slow to obey, Sally, not intending to hit anyone, fired about 15 rounds into the air. One of these ricocheted off a stone column and struck and killed a customer in the bank. Sally and Ralph were charged with murder of the customer. Which of the following is correct? 
Sally can be convicted of murder, because she did the act of killing, but Ralph cannot be convicted of either murder or manslaughter.  Neither can be guilty of murder, but both can be convicted of manslaughter based upon an unintentional homicide.  Sally can be convicted only of manslaughter, but Ralph cannot be convicted of murder or manslaughter.  Both can be convicted of murder.
