Jose Martin Hernandez, 56, was found shot to death on November 6, 2016, in Hayward, California. He and 42-year-old Leonides Rocha were discovered with gunshot wounds outside the apartment building where they lived, in the area of Manon Avenue and Ranker Place.

Hayward police linked the double killing to an ongoing three-month gang feud between rival subsets of a Northern California street gang. Investigators used a large-scale wiretap operation as part of the probe. Two suspects, Anthony Wolfe Jr. and Oscar Aguilar, were later arrested and charged; both pleaded no contest to two counts of voluntary manslaughter, with Wolfe receiving a 21-year state prison term and Aguilar a six-year term. Police testimony at the preliminary hearing identified Wolfe as a gang member and Aguilar as an associate, and cited the gang rivalry and alleged shouting of gang-related phrases before the shooting as motive-related details.

Anyone who knew Hernandez, Rocha, or had information about gang activity in south Hayward around 2016 is asked to come forward.
