Ricardo Diaz, 33, was fatally shot in the early morning hours of March 11, 2013, at an apartment complex in the 7000 block of Hillcroft Avenue in Houston, Texas. Initial reports say an unknown assailant approached Diaz and fired multiple times before fleeing; Diaz was later pronounced dead at the hospital. The Houston Police Department’s Homicide Division canvassed the area, interviewed potential witnesses and reviewed nearby surveillance, but no immediate suspects were identified.

Investigators described the motive as unclear, with possibilities including a personal dispute or random violence. Leads dwindled over time and the case grew cold; Crime Stoppers offered a reward for information and the department continued to appeal to the public. The Cold Case Unit has periodically reviewed unsolved homicides like this one. If anyone knew Ricardo, was in that area that morning, or has information that could help, please come forward. Who has information about that March 11 night?
