La Mesa, California — On Sunday, August 6, 2023, two La Mesa Police Officers contacted a suspect who had an active felony warrant for burglary in the parking lot of a condominium complex at 8000 University Avenue. Officers had confirmed the status of the subject’s felony warrant and obtained a photograph of the suspect prior to contacting him. At approximately 4:13 p.m., the officers saw the suspect standing outside of the passenger side of a vehicle parked in the lot. When officers contacted the suspect, he took out a handgun and pointed it directly at an officer who was standing in front of the vehicle. It appears the suspect tried to fire at the officer multiple times but the firearm malfunctioned.

In response, one officer discharged his firearm multiple times at the suspect as he ran through the parking lot. As the suspect continued to run towards University Avenue, it appeared the suspect was trying to manipulate or clear the firearm of the malfunction. The officer discharged his firearm, striking the suspect in the upper body multiple times. This incapacitated the suspect and caused him to drop the firearm. Officers rendered first aid and called for paramedics but the suspect was pronounced deceased at the scene a short time later. The preliminary investigation into this incident indicates a passing vehicle was struck by a round but the motorist in that vehicle was not struck. There was also at least one round that struck a building within the lot. No officers or other persons were injured during this incident.

The suspect in this incident has been identified as Jason Hampton of La Mesa. He is described as a 41-year-old white male. The officer involved in the shooting has been identified as Brian Heller. He has been employed by the La Mesa Police Department for approximately six years. He is currently assigned as a Master Patrol Officer in La Mesa and has been placed on paid leave per the La Mesa Police Department’s standard protocol following an officer-involved shooting incident.

Detectives are continuing to gather evidence, interview witnesses, and examine the circumstances surrounding the shooting. A loaded 9mm handgun was recovered at the scene.

The family of a Tulare man killed by police released video this week they said shows he was not a threat to officers, who shot him in the back as he fled. Joel Villegas was killed by Tulare police about 3:15 p.m. April 16 after a 911 caller reported seeing someone in the area of Bardsley Ave and Vetter Street with a knife, Tulare police said in a news release. Villegas, 34, was remembered by family as a doting father and a person others wanted to be around because he made them smile. “What they did was wrong,” older brother Armando Villegas said. “It was unfair to his wife and kids and family. He mattered.” His family released video from a Tulare officer’s body-worn camera that shows the officer yelling commands as Villegas runs away from him. At one point he trips, before getting up again and continuing to flee. The video shows Villegas never advanced on police before officers fired several rounds. Officers in the video can be heard saying Villegas was not breathing before an officer begins CPR. The shooting was “so egregious,” according to Dale Galipo, the attorney representing one of Villegas’s sons and his father.
