Trinidad Salazar Jr, a 33-year-old Hispanic man, was shot and killed January 15, 2014, in Dallas after an argument about roof shingles. He had gone to the home of 38-year-old Ociel Garcia to either retrieve the shingles or get more money for them. The two had previously argued over the sale.

Garcia drew a .40 caliber Glock and fired a warning shot into the ground. When Salazar lunged toward him unarmed, Garcia fired a second shot that proved fatal. Garcia’s wife witnessed the shooting and called 911; Garcia was arrested and booked for murder and was held on a $500,000 bond. Garcia admitted Salazar did not have a weapon.
