Maria Perez, 42, was found fatally shot at her Covina, California, home on April 11, 2018. Emergency responders pronounced her dead at the scene after discovering multiple gunshot wounds.

Investigators quickly focused on her estranged ex-husband, Miguel Angel Prieto, as the primary suspect. Prieto was taken into custody in Long Beach later that day in a black work van; officers reported finding a revolver in the vehicle that was believed to be the murder weapon. Authorities say Prieto had been on probation for a prior assault with a deadly weapon charge.

Police described a pattern of violent incidents involving Prieto in the weeks before Perez’s death, including a February 9 shooting in Azusa that left a woman dead and an April 7 shooting at a restaurant in Long Beach owned by Perez’s uncle. Those events were cited as part of the investigation into the threat Prieto posed to people he believed were connected to Perez.

If anyone knew Maria Perez or has information about her relationships or movements in the days before April 11, please come forward.
