Shaun Diamond, 45

Shaun Diamond, a 45-year-old white man, died Wednesday, Oct. 29, after he was shot in the 100 block of North San Marino Avenue in San Gabriel, according to Los Angeles County coroner’s records.

About 4 a.m. on Oct. 28, Diamond was part of a 14-member team serving a search warrant at a home as part of a multi-agency operation targeting the Mongols Motorcycle Club.

As the group smashed through the front door of the home with a battering ram, a gunman fired a single shot, striking Diamond in the back of the head.

The suspect, David Martinez, a 37-year-old Latino, has been charged with murder, according to prosecutors. Martinez, allegedly a member of the motorcycle club, also faces gun and gang allegations. Martinez’s criminal history includes assault with a deadly weapon and domestic violence.

Diamond was a 16-year law enforcement veteran who also worked with the LAPD and Montebello police. He joined the Pomona Police Department in 2006 and had been a member of the SWAT team since 2008.

“He loved being on the SWAT team,” said Pomona police Chief Paul Capraro.

Diamond was described as a family man with an “incredible sense of humor.”

In addition to his SWAT duties, Diamond worked in downtown Pomona and participated in community outreach efforts such as Special Olympics events and SWAT demonstrations for school children.

"He's somebody that anybody would get along with," Capraro said. "If you went door to door and asked any of those people, they would tell you ... they enjoyed working with him."

He is survived by his two children.
