UPS workers returned to the distribution facility this morning, a day after 38-year-old driver Jimmy Lam shot and killed three coworkers before turning the gun on himself.
Lam had worked at UPS for 18 years. He filed a grievance in March claiming he was working excessive overtime. An official with the Teamsters Union said it seems he specifically targeted the three drivers who died on the scene. Two other UPS employees who were injured have been released from the hospital.
Grief counselors joined returning workers at the UPS facility today. A spokeswoman says the company has marshaled additional drivers, loaders, and management from other locations to help with the backlog of deliveries caused by the attack.
Investigators are trying to figure out why Lam opened fire on his colleagues. Meanwhile, mourners have put makeshift memorials up at two corners of the building with flowers and signs.
