Derrick Tyrone Williams, a 40-year-old African American man, was fatally shot in the chest on November 5, 2011, in Houston, Texas. The shooting occurred about 3:35 p.m. in the courtyard of an apartment complex at 4250 West 34th Street; Williams died at the scene.

Houston Police Department investigators say the shooting followed an argument between Williams and Artavious Deon Hollins. Hollins reportedly went into his apartment, retrieved a gun, returned to the courtyard and shot Williams once before fleeing. Hollins, then 37, was identified and arrested on December 16, 2011, and charged with murder in the 248th State District Court. The HPD Homicide Division, led by Sergeant R. Rodriguez and Officer M. Chaney, handled the case.

If anyone witnessed the courtyard argument or the moments before or after the shooting, please share what was seen.
