Police: UPS shooter in San Francisco armed with stolen guns

SAN FRANCISCO – A San Francisco UPS driver who killed three colleagues in a shooting rampage at a company warehouse was armed with two stolen guns and appeared to target his victims, police said Friday.

Police Commander Greg McEachern told a news conference that investigators have not yet determined Jimmy Lam’s motive, but “the shooting appeared purposeful and targeted.”

Lam, 38, shot and killed three fellow drivers and wounded two others before killing himself in front of police in the June 14 shooting. An 18-year veteran of UPS, Lam opened fire at a morning meeting of UPS drivers before the drivers went out on deliveries.

Lam began by shooting Benson Louie, 50, in the meeting before turning the gun on Wayne Chan, 56, McEachern said. He then walked outside and confronted Mike Lefiti, 46, and fatally shot him multiple times.

Lam didn’t say anything during the rampage, McEachern said.

Lam was armed with two stolen weapons. One was an assault pistol that is illegal in California and was stolen in Utah, which he used in the killings, McEachern said. Lam also had a semi-automatic handgun stolen from Napa County, California.

It was not known who stole the weapons, McEachern said.

A San Francisco Police Department official told the Associated Press last week that Lam appears to have felt disrespected by co-workers, but it’s not clear what role that played in the shooting.

“We are going to work painstakingly to try to get a motive,” McEachern said.

Investigators have recovered a journal from Lam’s home and are reviewing it, along with his computer, he said.
