Death and succession
The North Providence, Rhode Island Fire Department Rescue Squad received an emergency call from a Douglas Avenue address on July 11, 1984 at around 11:30 a.m. It was later revealed that this was the home of Patriarca's girlfriend; his wife had died in 1965. He then married a former nightclub hostess and was living with her in Johnston, Rhode Island at the time of his death. When emergency workers arrived, they found Patriarca to be in full cardiac arrest and rushed him to Rhode Island Hospital, where doctors tried to revive him with electrical defibrillation and implanting a cardiac pacemaker. He was pronounced dead at 1 p.m. of a heart attack at the age of 76. He is buried in Gate of Heaven Cemetery, East Providence, Rhode Island.
Patriarca was under indictment for two murders when he died. The Boston Globe wrote: "In a business where violent death is often inevitable, Patriarca died relatively peacefully, unable to outwit failing health caused by a heart condition and diabetes that led to amputation of a gangrenous toe."
