Then he called the cops and was attacked on the way to surrender, fired on one who attacked and shot the second one in the arm who was holding a pistol and refrained when the other guy threw his hands up and turned around.    He could not have handled things any more professionally... At 17.  The main picture is the chubby kid eating a bowl of ice cream.  Good fucking luck getting a jury to convict. Especially murder one charges which requires premeditation.
