SNIP: For almost three years, Steven Nisenfeld searched for a reasonable explanation of why his 18-year-old son, Bryan, left a midday literature class at Roger Williams University on February 6, 1997, and was never heard from again. In January, things began to make more sense after the elder Nisenfeld traveled from his New Jersey home to the Scituate headquarters of the Rhode Island State Police.
Bryan Nisenfeld's death remained shrouded in mystery even after a few of his bones washed up on Hog Island in Narragansett Bay, near Roger Williams' Bristol campus, in August 1997. But the small amount of physical evidence precluded an autopsy, and, says Maj. Steven Pare, state police didn't find any indication of suspicious activity in connection with Nisenfeld's disappearance or death. The conclusion is that the college freshman, who showed signs of being emotionally upset in the week before he vanished, either committed suicide or died after accidentally falling into the bay.
