SAN FRANCISCO — A gunman killed three coworkers and wounded two others at a sprawling UPS facility here Wednesday before fatally turning the gun on himself, UPS and police said.

Police identified Jimmy Lam, a disgruntled employee from San Francisco, as the shooter in a press conference late Wednesday here.

Responding officers encountered multiple shooting victims in the building at around 9 am local time, San Francisco Assistant Police Chief Toney Chaplin said during a news conference outside the building.

When one of the police teams located Lam, who was armed with an assault pistol, "the suspect put the gun to his head and discharged the weapon,” Chaplin said.

Victims of the rampage were found inside and outside the UPS building, according to authorities.

Lam was given medical treatment at the site but died.

The wife of one UPS employee described a chaotic scene inside the UPS facility, where the assailant shot several people execution-style.

Police are not releasing information about the victims until families are notified, Chaplin said.

Streets in the city's Potrero Hill area near the building were sealed off for much of the day.

The large UPS processing facility is about two miles south of downtown and employs about 350 people. The four-story building, which covers an entire city block, is clearly visible along Highway 101 as drivers go to downtown San Francisco.

Zuckerberg San Francisco General Hospital, located about a mile from the facility, was put on alert following the shooting.

KPIX-TV reported the shooting happened during the daily 9 a.m. drivers' meeting. Auto shop owner Robert Kim told KPIX he heard five to eight rapid gunshots, then saw "a mob of UPS drivers” running down the street screaming “Shooter, shooter!”

After police began their search of the building, a long column of two rows of UPS employees were escorted out of the building by armed officers, KPIX reported.

The shooting took place in a different part of the building from the area where customers pick up and drop off packages.

UPS said in a statement that the company was cooperating with the investigation.

“The company is saddened and deeply concerned about affected employees, family members and the community we share. Our thoughts and prayers are with all those touched by this incident,” the statement read.
