The mother of a Commack man claims he died in a July 2013 car crash because Suffolk County police did not arrest him earlier that night for driving drunk after a crash. Kathi Fedden claims in a lawsuit filed in federal court in Central Islip on Monday that police had Peter Fedden’s car towed to a nearby schoolyard and then drove him home, even though he was "severely intoxicated" and visibly injured.Suffolk County police said in a statement Tuesday night that they don’t comment on pending litigation. County officials also could not be reached for comment Tuesday night.
