SHERMAN OAKS (CBS) — A $50,000 reward is being offered to help find the killer of a father, who was shot to death for taking too long to cook a fast food order.

Raul Lopez, 38, was shot to death while working at Hoagies & Wings on Ventura Boulevard in Sherman Oaks on June 29. A group of five young men reportedly got disruptive, and one of the customers got angry with Lopez over how long it was taking for food to be prepared.
