An Attleboro woman has been indicted for the 1985 murder of her newborn son, the latest cold case to move forward through Bristol County District Attorney Thomas M. Quinn III’s expanded efforts to identify remains through DNA testing and other means. Quinn announced today that Dianne Curry Peck, 59, of Attleboro, was indicted this afternoon by a Bristol County Grand Jury. She is scheduled to be arraigned Tuesday morning, June 30, in Fall River Superior Court.
