The witness said at least three people were shot. "Go!'" said Jessica Franklin, 30, who was riding the bus to work when it made a regular stop in front of the UPS facility. The driver says he worked with Lam for more than a decade and describes him as a "loner".
Two other people were shot and survived, he said.
The building is located in the Portero Hill, which is about 2.5 miles from downtown San Francisco. After a shooting that took place on a baseball field just outside of Washington, D.C., a gunman opened fire at a San Francisco UPS facility, leaving four dead including the shooter.
The official spoke on condition of anonymity because the investigation is ongoing.
The gunman was identified by authorities as San Francisco resident Jimmy Lam. Two others were wounded.
Workers returned to the facility Thursday, a day after the shooting led police to evacuate the warehouse.
Mr Toia said he was able to tell his cousin he loved him.
By late afternoon, friends had set up a memorial to Lefiti with flowers and balloons at a local supermarket near the UPS warehouse.
"We can not provide information as to the identity of persons involved at this time, pending the police investigation", the statement said.
The I-Team also saw police at the scene searching a 2012 BMW that came back registered to Lam.
The gun shot himself fatally when he was confronted by the police, reports said.
He says police won't know more information about weapon until they test-fire it.
"They were banging on the bus and they were screaming, 'Go! Go!" And the driver did. Police are now conducting a search of the building, they said. Although police know the name of the suspect they were not yet releasing it.
Another neighbor said it was sad of course for the people who got killed and that it was something they'd never expect.
The deadliest mass shooting in modern USA history occurred in June 2016 when a gunman claiming allegiance to the Islamic State militant group killed 49 people at the Pulse nightclub in Orlando, Florida. "We recognize the impact this shooting is having on the City and UPS".
"It was a frightful scene", Chaplin said.
But Assistant Police Chief Toney Chaplin told a news conference the shooting was not an act of terrorism. All of the workers involved were on the clock and gathering for their morning meeting before heading out with their parcels, he said.
"Our investigators are going through painstaking interviews with everyone who was in the building", he said.
A Twitter user across the street from the building tweeted that he heard seven or eight gunshots and saw employees standing on the building's roof parking lot with their hands up.
"My dad is in there and he was shot", the woman said, shaking her head.
In its statement, UPS said the company wasn't immediately sure of the status of the survivors who were taken to the hospital.
UPS said in a statement that there was a "shooting incident involving six employees" within the company's facility in the neighborhood of Potrero Hill.
A person wearing a UPS uniform opened fire on three fellow employees and then "turned the gun on himself", UPS spokesperson Steve Gaut said.
Two other victims are being treated for injuries at San Francisco General Hospital.

The suspect was dressed in a UPS uniform but police have not yet confirmed if he was an employee, according to authorities. They walked away calmly with emergency vehicles nearby.
In a series of tweets that began just after 9 a.m., police told the public to avoid the area.
