(BANT) – The man who shot and killed three people and wounded two others before turning the gun on himself at a San Francisco UPS facility last week used a stolen, illegal assault-type pistol and appeared to specifically target his victims, according new information released by San Francisco police officials.

Police are still not sure why Jimmy Lam, 38, walked into a meeting on June 14 with several other UPS employees at about 8:50 a.m., drew a pistol with an extended 30-round clip and, without warning, shot 50-year-old Benson Louie, according to police Commander Greg McEachern.

Lam then turned on 56-year-old Wayne Chan and shot him, too, before shooting two other people who subsequently survived their injuries.

At this point, as other employees were fleeing for their lives, Lam calmly walked out of the building, found 46-year-old Michael Lefiti on the corner of 17th Street and San Bruno Avenue and put several bullets into him, McEachern said.

Lam then walked back into the UPS building as police were arriving at the scene. The first officers to arrive assembled a “contact team” and entered the building to look for Lam, who was wearing his UPS uniform at the time. During their search, they found other UPS employees hiding or trying to get out of the building.

“They told some to shelter in place and some to get outside,” McEachern said.

After about 10 minutes, the officers found Lam pointing a gun at his own head. Lam pulled the trigger after being told to put the gun down, according to McEachern.

The officers quickly spotted Louie and Chan lying next to where Lam had shot himself and took the two men outside to get emergency medical aid, but Chan and Louie, along with Lefiti, all died. At this point, police believe Lam fired 20 rounds during the attack.

Investigators have interviewed more than 100 witnesses, collected multiple cell phones, computers and a journal from Lam’s house and are reviewing video footage from the UPS building and from the officers’ body cameras, McEachern said.

They also recovered a backpack at the scene that held one box of ammunition and another semi-automatic pistol, also stolen, that doesn’t appear to have been fired in the attack.

The shooting of the three men who died “appeared purposeful and targeted” and investigators are still trying to determine if the surviving victims were also targeted, McEachern said.

“Mr. Lam passed employees without shooting at them, apparently looking for the people he shot,” McEachern said.

How Lam got the weapons past building security and what his motive was are questions that are still being investigated.
