A 25-year-old Los Angeles County, CA, sheriff's deputy was killed in a crash while riding his motorcycle in Corona, police said Saturday.

According to the Corona (CA) Police Department, officers and firefighters were sent shortly before 4:30 p.m. Friday to the area of Hidden Valley, for report of a severe injury-related traffic collision. Upon their arrival, authorities learned two motorcycles and two vehicles were involved in the collision.

According to police, one of the motorcyclists — who was later identified as Upland resident Philip Borja — succumbed to his injuries at the hospital. Borja was an off-duty Los Angeles County sheriff's deputy assigned to the Norwalk station, reports KCBS.
