UPDATE  |  A man found dead in the backseat of a vehicle parked near Wilson High School had allegedly threatened his estranged wife with a gun and was being sought by police several hours prior.

Francisco Parra-Garcia, 62, of Long Beach, was allegedly found rummaging through his wife’s car while it was parked on the 300 block of Wilson Street at approximately 8:20AM, according to Costa Mesa Police Lt. Paul Beckman.

When the wife approached the vehicle, Parra-Garcia confronted her and an argument ensued, escalating to Parra-Garcia pulling out a handgun, prompting the wife to defend herself with pepper spray, according to Beckman.

At one point during the dispute, Parra-Garcia attempted to fire the gun, but it failed to discharge, Beckman said.

At approximately 12:30PM, Long Beach police, who were assisting with the investigation, found the man in his 1998 Mitsubishi Montero in the area of 10th Street and Bennett Avenue in Long Beach, Beckman said.

Parra-Garcia was found in the rear passenger-side seat and was “non-responsive” as detectives tried to rouse him, according to Beckman.

The weapon has yet to be recovered and there were no obvious signs that he took his own life, Beckman said.
