Police: Missing man's death suspicious

PROVIDENCE, R.I. (WPRI) - Providence police are calling the death of a missing Massachusetts man suspicous.

The medical examiner's office is working to determine a cause of death for Gregory Hart, who's body was found in the Woonasquatucket River on Tuesday.

Experts said on Wednesday that further studies are being done in order to determine what caused 23 year-old, Hart to die.

Hart who is from Dedham, Massachusetts, was last seen in Providence leaving the Red Room Bar early Sunday morning.

Hart's mother said there are conflicting reports as to what happened that night.

"He was with two other people, supposedly, actually even a few more. And there was a fight inside that bar and I don't know who was fighting with who, there are all different conflicting stories," said Marianne Hart.
