Officer Brian Hayes, 35, of the Anaheim Police Department.

Officer Nicole Anderson, 32, of the Simi Valley Police Department.

Officer Ryan Stringer, 26, of the Alhambra Police Department.

We mourn the recent tragic deaths of three officers from different police departments in Southern California.

Brian Hayes, 35, of the Anaheim Police Department and Nicole Anderson, 32, of the Simi Valley Police Department, were killed in the crash of a small airplane in Arizona on July 16. They were the only passengers aboard the single-engine plane that went down during takeoff at Winslow-Lindbergh Regional Airport in Arizona.

Officer Hayes had been a police explorer and reserve officer before being hired by the Anaheim Police Department in 1999. He worked patrol for the department. Officer Anderson started with the Simi Valley Police Department in 2003. In her career, she worked as a bicycle officer, a member of the department’s crisis negotiation team, and most recently, the department’s youth services officer.

Only days before, on July 10, 26-year-old Alhambra Police Officer Ryan Stringer was killed in the line of duty when his patrol car collided with another police vehicle while responding to a robbery-in-progress call. His colleague in the other vehicle was briefly hospitalized.

Our thoughts and prayers are with the families, friends and colleagues of Officers Hayes, Anderson and Stringer during their time of grieving.
