**FILE**Rev. Richard R. Lavigne, a Roman Catholic priest, pleads guilty to two counts of indecently assaulting two adolescent boys at Newburyport Superior Court in this June 25, 1992 file photo in Newburyport, Mass. The body of Danny Croteau,13, was found in 1972, in Chicopee, Mass. Lavigne was the only named suspect but has never been charged. After hundreds of new documents in the case were made public in January 2008, Danny's aging parents asked the state's attorney general to launch an independent investigation to determine who was their son's killer.
