Benson Louie, 50, was one of three UPS employees killed during a workplace shooting at a Potrero Hill facility in San Francisco on June 14, 2017. Two other employees, Wayne Chan and Mike Lefiti, were among the victims.

Reports say Lam had been under significant personal and professional stress and had complained about excessive overtime, but investigators found no clear, direct conflict linking him specifically to Louie or the other victims. Louie was remembered as a volleyball coach and a dedicated employee; his widow, Sandy Lim, later joined other family members in suing UPS, alleging inadequate security at the workplace.

What details about Louie’s life or the workplace environment might help explain how this tragedy unfolded?
