Ricardo Galvez, a 29-year-old Downey police officer and former U.S. Marine, was shot and killed on November 18, 2015 while seated in his personal vehicle in the police station parking lot around 11 p.m. He had been preparing to go off duty after a K-9 training session when two individuals approached and opened fire at close range. Investigators later determined the attack was a botched robbery; the assailants did not know Galvez was an officer.

Three suspects were arrested: Abel Diaz, who was 16 at the time and charged with murder with a special circumstance that the killing occurred during an attempted robbery plus attempted second-degree robbery and gun and gang allegations; Jeremy Alvarez, 21; and Steven Knott, 18. Detectives recovered a revolver believed to be the weapon, and the suspects admitted to attempting the robbery. Knott later pleaded guilty to first-degree murder and attempted robbery with personal use of a firearm and received 50 years to life; Alvarez pleaded guilty to second-degree murder and attempted robbery and received 30 years to life. Diaz, charged as an adult, faced a possible life sentence if convicted.

Galvez had served five years with the Downey Police Department. His death had a deep impact on colleagues and the community. Did anyone in the Downey area witness activity around the station that night or have information about the suspects leading up to November 18, 2015?
