Prosecutors say police found Joseph Donohue's body wrapped up and weighted on his houseboat in Charlestown Sunday.

New information has been released on the murder of a man found stabbed to death on a houseboat in Charlestown last weekend.

A 24-year-old faces a murder charge in connection with the death of a man on a luxury houseboat in Boston on Sunday.

Police were conducting a welfare check at the houseboat, which was docked at the Charlestown Marina, when they found the body of Joseph Donohue, 65, police said.

The Boston attorney who was found stabbed to death on his houseboat was wrapped and weighted down, a prosecutor said.

The suspected killer allegedly told police that the victim was at DB’s Golden Banana, but gave another story to his family, prompting a sweep of the houseboat.
