On March 22, 2002, Craig Edward Schafer, 50, was one of four men fatally shot at Bertrand Products, an aircraft parts plant in South Bend, Indiana. The attacker, identified as 54-year-old co-worker William F. Lockey from shipping and receiving, entered the facility armed with a rifle and a shotgun and opened fire during a meeting, targeting certain individuals.

Also killed were David J. Arpasi Sr., 73; John Contadeluci, 47; and Robert C. Downs Jr., 42. Five others were wounded, including three police officers. Lockey fled in a stolen company van, fired at officers and construction workers during a multi-state pursuit, and died by a self-inflicted gunshot inside the moving van as police closed in near a roadblock in Niles, Michigan. Reports noted Lockey had prior mental health concerns and a previously thwarted planned attack.

Did anyone who worked at Bertrand Products or lived in South Bend at the time remember warning signs about Lockey or specific tensions in the workplace?
