Suicide by Stupid Mother.
It is no wonder that he has no sense after being raised by someone who can't think.
"I want to know who killed my son for no reason at all"
You killed your son, lady. By your negligence and irresponsibility, letting him (a minor) run around with the car keys at 3 in the morning, and consequently robbing a Liquor store. It all starts at home and unfortunately two police officers have to live with having to kill your son due to the consequences of your irresponsible parenting.
