Gabriel Hernandez was 18 when he was found among five family members slain in a dirt lot outside their home at 701 East Baseline Road in Phoenix on August 29, 1992. He was discovered with his sister, Librada Zubia Hernandez, 30; her husband, Eloy Zubia, 28; and their two children, Rocio, 9, and Eloy Jr., 6. A passerby located the bodies at about 2:10 p.m.; investigators say all five had been shot execution-style.

A neighbor later reported hearing seven gunshots that Saturday morning in a pattern described as four shots, a pause, then three more. Detectives investigated several lines of inquiry, including possible gang or drug connections, but say they found no evidence to support those theories. Robbery was ruled out because nothing had been taken from the family.

More than three decades later the case remains unsolved and no arrests have been announced. Anyone with information about the killings is asked to contact the Silent Witness program or Phoenix police.
