Shirley Rose Thompson Mooser, 64, was killed on July 1, 1993, in San Francisco during the mass shooting at 101 California Street. The attack took place in the law offices of Pettit & Martin, where the gunman, Gian Luigi Ferri, entered the building armed with multiple firearms and opened fire on employees and visitors. Ferri’s rampage fatally wounded eight people, including Shirley Mooser, and ended when he died by suicide at the scene.

The shooting prompted lawsuits by victims’ families, including wrongful death claims against the manufacturers of the firearms used by Ferri. Reports say Ferri had a history of grievances and mental health issues that were examined after the attack. Shirley Mooser’s death is one of several that sparked broader public discussion about workplace safety and gun policy.
