On the evening of April 22, 2017, 21-year-old Santiago Vasquez of Hayward, California, was at a birthday party in College Heights Park when he was struck by multiple rounds of gunfire around 8 p.m. He was taken to a nearby hospital and died shortly after from his injuries. The shooting prompted an intensive investigation by the Hayward Police Department with assistance from the Alameda County Sheriff’s Office and the U.S. Marshals Service.

The investigation resulted in arrests later in 2018. Jose Esquivel, 24, was arrested in Dublin on October 3, 2018, and Carlos Guevara, 24, was arrested in San Leandro on September 26, 2018; both were charged with felony murder and weapons offenses and held without bail. A third man, Miguel Mata, 25, was arrested in San Lorenzo on October 9, 2018, and faced charges including armed robbery and accessory to commit murder; he was held on $270,000 bail. Pre-trial hearings were scheduled for November 15, 2018, at Dublin’s East County Hall of Justice.

Does anyone who attended the April 22 gathering or who was in College Heights Park that evening have information that could shed light on what happened?
