Mark Dean Burnough II, 17, of Glenn Heights, Texas, was shot and killed on April 26, 2017, during an argument over an iPhone at an apartment complex in the 6900 block of South Cockrell Hill Road near Interstate 20 in South Dallas. He was taken to a hospital but succumbed to his injuries.

A dispute escalated into a gunfight in which Burnough was shot. Gibbs and Gordon were later arrested and charged with capital murder; a third suspect known as Little Josh remained at large. Police released an edited video showing three young men walking across the complex parking lot dressed in hoodies and jeans.

Burnough is remembered by family and friends as a bright, respectful young man with a sweet spirit. Anyone who was at the apartment complex that day or who has information about Little Josh or the shooting is asked to come forward.
