ONTARIO, Calif. (KABC) -- A funeral service was held Thursday for the Pomona SWAT officer who was shot and killed while serving a search warrant in San Gabriel.
Hundreds of law enforcement officers filled Citizens Business Bank Arena in Ontario to honor Officer Shaun Diamond.
In addition to officers from Pomona Police Department and other regions, Gov. Jerry Brown and Attorney General Kamala Harris attended the service as well.
Diamond's friends and colleagues said he was a consummate professional in everything he did. The officer was described as "stern, compassionate and fatherly" when it came to guiding trainees at work and also teaching local school children about police work.
Authorities said the warrant was part of a sweep targeting criminal motorcycle gangs.
Diamond had 16 years of law enforcement experience. He was with the Los Angeles Police Department for seven years and also worked for Montebello Police Department before being hired by the Pomona Police Department in 2006. He joined the Pomona SWAT team in 2008.
A graveside service in Covina followed the funeral service. A procession left Citizens Business Bank Arena around noon and traveled on the 10 Freeway and through downtown Pomona to get to Forest Lawn Memorial Park. The westbound 10 Freeway briefly shut down for the procession, which exited off Garey Avenue, traveled through Pomona surface streets and re-entered the 10 at White Avenue and exit at Via Verde Avenue.
Pomona Police Chief Paul Capraro spoke about Diamond's dedication to the city of Pomona.
"Shaun loved working the assignment in the downtown community and the downtown community loved him right back. It is only fitting that we bring Shaun through his beat during today's processions. You will recognize it by a blue ribbon tied to every light pole and every tree in the area. This was done by the downtown community as a symbol of their love for Shaun and their respect of all of us," Capraro said.
Police say the suspect accused in the shooting, David Martinez, 36, is possibly a member of the Mongols motorcycle gang. He has been charged with capital murder and is being held without bail.
Officer Diamond is survived by his wife, two children, father, mother, brother and sister. He was 45 years old.
