A Long Island criminal defendant tried faking his death to avoid sentencing, but the phony death certificate his lawyer submitted had a glaring spelling error that made it a dead giveaway for a fraud, prosecutors said Tuesday. Robert Berger, 25, of Huntington, New York, now faces up to four years in prison if convicted in the alleged scheme. That's in addition to pending sentences for earlier guilty pleas to charges of possession of a stolen Lexus and attempted grand larceny of a truck — punishment prosecutors say he was looking to avoid.
