On January 9, 1982, then 37-year-old Conigliaro was in Boston to interview for a broadcasting position when he suffered a heart attack while being driven to the airport by his brother Billy. Shortly thereafter, he suffered a stroke and lapsed into a coma. Conigliaro never fully recovered and suffered slight brain damage due to the stroke, until his death more than eight years later, in February 1990, at the age of 45 from pneumonia and kidney failure. In commemoration, the Red Sox wore black armbands that season. He is interred at Holy Cross Cemetery in Malden, Massachusetts.
