Police say they're investigating as suspicious the death of a college student whose body was pulled from a Rhode Island river this week.
Gregory Hart was last seen Sunday morning in Providence, where he and friends had visited a nightclub.
A body preliminarily identified as Hart's was removed Tuesday from the 18-mile-long Woonasquatucket (woon-as-kah-TUK'-et) River.
The medical examiner's office said Wednesday it was performing an autopsy and didn't know the cause of Hart's death.
The 23-year-old Hart was a student at the University of Massachusetts at Amherst, a two-hour drive northwest of Providence. He was from Dedham (DEH'-duhm), Mass.
Hart's mother, Maryann Hart, tells The Providence Journal newspaper she suspects foul play, though police are still investigating.
