Both victims sustained a gunshot wound to the head. The coroner's office ruled the manner of death for both men as a homicide.

Police allege that the defendant told them he was trying to buy cocaine when he saw one of the car's occupants reach for "something" so he opened fire.

A preliminary hearing is scheduled for March 14.
