On April 3, 2015, Glen Williams, a 54-year-old man from Houston, Texas, was shot and killed after an altercation at the Corner Food Mart on Selinsky Road. Surveillance at the store captured a man brandishing a weapon during an argument between Williams and a woman. That man became involved in the confrontation, and later followed Williams and his 24-year-old son, Carl Williams, as they left.

When Glen and Carl returned to their residence at the Crystal Springs apartment complex, both were shot. Glen collapsed near the apartment door; Carl managed to move about 30 yards before dying of his wounds. Authorities arrested 38-year-old Christopher Mallett and charged him with capital murder in the 228th State District Court in connection with the two deaths. The motive for the initial argument and the escalation to deadly violence remains unclear.

Did anyone in the area see the confrontation at the Corner Food Mart or the men leaving toward Crystal Springs that night?
