May 16, 2017 (Lakeside) – Names of the deputies involved in the fatal shooting May 10th on the Barona Reservation in Lakeside have been released by the Sheriff’s Department. Deputy Matthew Addenbrooke fired a shotgun, Deputy Patrick Farber fired a patrol rifle, and deputies David Williams and Aaron Brooke each fired less-lethal shotguns.
Deputy Williams is assigned to the Ramona Substation and has been with the Sheriff’s department for 10 years. Deputies Brooke, Farber and Addenbrooke are with the Lakeside substation and have been employed by the department for 15, 9, and 3 years respectively.
The suspect has been identified as Jeroen Peter Koornwinder, 50, of Santa Barbara. According to the Medical Examiner, cause of death was a gunshot wound to his upper torso.
Deputies fired at Koornwinder after multiple nonlethal attempts to halt his pursuit had reportedly failed, including a “stop stick” tire deflation device. After it was deployed, Koornwinder accelerated his vehicle and tried to hit deputies.
“Two deputies fired at Koornwinder to prevent him from hitting their partners,” says Lt. Greg Rylaarsdam with the Sheriff’s homicide unit. Koornwinder kept driving, turning south on Ketuull Uunyaa Way before colliding into a Sheriff’s marked patrol vehicle. The collision turned the patrol SUV and pushed it back into a Tribal Enforcement vehicle.
Koornwinder kept fleeing around the collision and then collided with a Lexus before running off road, coming to a stop. Four women were in the Lexus and three sustained injuries, all in their 60s and 70s. Two remain hospitalized with non-life threatening injuries. A 17-year-old also in the Lexus was not injured.
Deputies had responded to a call for help from Tribal police who reported the suspect sought for reckless driving had tried to ram a Tribal Police vehicle. Koornwinder died at the scene after he was shot.
