Manhattan DA Robert Morgenthau wants to hold a Queens tax preparer accountable for allegedly threatening to kill a prosecutor who's handling a grand larceny case against him. 54-year-old Jack Chang (not pictured) did a year in prison in the mid-'90s for funneling nearly $1 million from his clients to his own account; in April he was arrested on similar charges in a case that's being conducted by the same prosecutor who put him away the first time: Gilda Mariani, head of the money laundering and tax crimes unit.
