The California Highway Patrol (CHP) was in pursuit of a motorcycle traveling at high speed southbound on the 57 Freeway from the 210 Freeway. The suspect exited the freeway and continued at a high speed on surface streets, where they collided with a truck at the intersection of Orangethorpe Avenue and Lemon Street. The impact ejected the motorcyclist, who landed on the ground.
CHP officers arrived moments later and initiated CPR as the motorcyclist was unresponsive. The Fullerton Fire Department arrived shortly after and pronounced the suspect dead at the scene. Another individual was transported to a nearby hospital; their condition remains unknown.
The intersection of Orangethorpe Avenue and Lemon Street will remain closed for an undetermined period as CHP investigates the crash, with the Fullerton Police Department assisting.
