On November 12, 1985, Springfield, Massachusetts police officer Michael Schiavina, 28, was shot in the chest while on patrol with his partner, Officer Alain Beauregard. The two officers had approached a vehicle occupied by two men when one of the men opened fire. Officer Schiavina died at the scene; Officer Beauregard was critically wounded and died three days later from a gunshot to the head.

The shooter was identified as Eddie Ortiz, who had an outstanding warrant. A manhunt followed; when officers closed in on a hiding place Eddie Ortiz died by a self-inflicted gunshot. His brother, Juan Ortiz, who had been in the vehicle, was arrested. Prosecutors pursued Juan Ortiz under a felony-murder theory and he was convicted of two counts of second-degree murder and sentenced to life in prison.
