BOSTON (CBS) — A body found in the Charles River Tuesday morning has been identified as 23-year-old Jonathan Dailey. The Boston Architectural College student was last seen October 2 at his apartment in Allston.

The body was found at about 7:30am by a Boston University rowing coach. Two sources told WBZ-TV’s Bill Shields that there were chains around the ankles of the body attached to two cinder blocks.

The Suffolk County District Attorney’s office has not released a cause of death, saying the investigation is ongoing.

“We rule out no possibility and we promise Mr. Dailey’s family a thorough, comprehensive search for the truth as we investigate his death,” Jake Wark, the spokesman for the Suffolk County District Attorney’s Office, said in a statement Tuesday evening.

Detectives went to Dailey’s apartment late Tuesday morning to speak with his family and to request dental records.

Dailey was from North Carolina and was in Boston studying to get his Master’s Degree. He lived in Allston with a roommate, Miles Smith, who says the two ate pizza and watched TV last Tuesday night.

“Right now my heart’s in a box put away,” Smith told reporters Tuesday afternoon. “I understand it’s my best friend who I love very, very much and I know that loves me.”

Smith doesn’t believe anyone would harm Dailey.

“Absolutely not, he was very charismatic, a great friend to all he met,” he says. “A tough tease, but everyone knew it was in good nature.”

The family had offered a $5,000 reward for information leading to Jonathan’s safe return.

The body of an older man was found in the same general area of the river on Monday.
