BUFFALO -- The only inmate convicted of murder after the 1971 Attica prison uprising has died in Canada, where he had made a name as a civil rights and peace activist.
The body of John Boncore, 61, was found March 13 in his home on the Adams Lake Indian Reserve in British Columbia, Barb McLintock of the Coroners Service of British Columbia said yesterday.
He reportedly had fallen earlier nearby, she said, but the cause of death has yet to be released because the investigation is ongoing. "There is nothing to suggest foul play," she said.
Thirty-two inmates and 11 civilian employees died during the five-day siege, including 10 hostages and 29 inmates killed when State Troopers stormed the prison's D Yard on Sept. 13, 1971.
In 1975, a state Supreme Court jury in Buffalo convicted Boncore of murder in the beating death of correction Officer William Quinn. He was sentenced to at least 20 years in prison.
Boncore, who had denied attacking Quinn with a two-by-four as alleged, was pardoned in 1976 by Gov. Hugh Carey.
After his release from prison, Boncore became active in several causes and eventually moved to Canada, Sharon Fischer, an activist and legal assistant, told The Buffalo News.
