Richard Baumhammers began by shooting to death a Jewish neighbor and setting her house on fire, then attacked others at a Chinese restaurant and Indian grocery. He painted racist graffiti and fired into two synagogues.
Baumhammers, 52, is imprisoned in Greene State Prison in southwestern Pennsylvania.
Richard Poplawski ambushed and killed Pittsburgh police officers Eric G. Kelly, Stephen J. Mayhle and Paul J. Sciullo II at his Stanton Heights home after they responded to a domestic disturbance call.
Poplawski surrendered more than three hours later, largely because he was bleeding from a leg wound inflicted during an exchange of fire with one of the officers, but not before peppering SWAT officers with fire from his 12-gauge shotgun, .357 Magnum and AK-47 assault rifle.
Poplawski was convicted and sentenced to death in 2011.
