Officials from many different agencies took place in the procession, paying tribute to Laguna Beach motorcycle officer Jon Coutchie.
The 42-year-old former U.S. Army Ranger is the first Laguna Beach officer to die in the line of duty in 60 years.
Coutchie was killed following a crash involving a pickup truck at the intersection of South Coast Highway and Cleo Street Saturday.
Police said Coutchie was going northbound on South Coast Highway trying to locate a speeding vehicle that had eluded another officer, when his motorcycle collided with a Chevrolet pickup truck that attempted to make a turn. He died at the scene.
A private viewing was held at the mortuary in Long Beach Tuesday.
A funeral service was scheduled for Friday.
