Pedro Diaz, 55, was shot to death on June 20, 2014, in Houston while driving home after closing his snow cone stand near I-45 and Aldine Bender. He was last seen at the stand; police believe he stopped his mini-van in the 100 block of Mill Stream and got out, after which the shooting occurred. A neighbor reported hearing yelling and gunfire, and nothing was taken from Diaz, leading investigators to consider the possibility of a random act of violence.

The Houston Police Department investigated but no arrests have been announced. Conflicting witness descriptions and a lack of direct evidence tying anyone to the killing have hampered the case, which remains an open cold case. The family has been vocal about wanting justice, erected a memorial, and shares stories with his grandchildren to keep his memory alive.

Anyone who may have information about Pedro Diaz’s movements that night or the events near Mill Stream is asked to come forward.
