David Olivares, a 21-year-old resident of Brentwood, was shot to death on February 14, 2020, at Woodland Hills Park in Pittsburg, California. An assailant approached and fired multiple shots; despite rescue efforts by police officers and fire personnel, Olivares died at the scene. Early in the inquiry detectives had few leads about motive.

Pittsburg investigators later identified three suspects: 24-year-old Jose Quintanilla of Brentwood, 21-year-old Angel Rodriguez of Oakley, and 21-year-old Sabrina Glenn of Pittsburg. Police say Glenn lured Olivares to the park; Rodriguez drove Quintanilla there; Quintanilla then appeared with a gun and shot Olivares. Prosecutors say Quintanilla acted out of jealousy, alleging Olivares had been romantically involved with Quintanilla’s wife, and that Quintanilla had deceived Rodriguez and Glenn about a planned robbery and a claimed sexual assault.

Both Rodriguez and Glenn testified against Quintanilla as part of plea deals. In December 2023 a Contra Costa jury convicted Jose Quintanilla of first-degree murder with enhancements for lying in wait and personal use of a firearm; sentencing is set for March 8, 2024. Does anyone have information about Olivares’s activities that night or about witnesses who were at Woodland Hills Park?
