WESTON - A Weston Town Hall employee may have died of natural causes, not a car accident.Preliminary reports say Ron Parenteau may have suffered heart failure before his car veered off of Georgetown Road and struck a tree. Emergency crews rushed to the scene, but attempts to revive him were unsuccessful.Those Parenteau worked with say he was weeks away from turning 70 and was preparing to retire. He was a maintenance worker, but his co-workers say he did so much more than what his job title entailed, calling him a Jack of all trades.
