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 named a “person of interest” in connection with the death of a man on a luxury houseboat in Charlestown now faces a murder charge, prosecutors said Thursday. Nora Nelson was arrested at the scene of the man’s death on Sunday night on a trio of warrants charging her with a variety of domestic violence offenses unrelated to the Charlestown case.

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.

Authorities on Wednesday identified the man who was found dead earlier this week on a houseboat in Charlestown as 65-year-old Joseph Donohue.

A distraught friend of the victim said he was a Boston lawyer and a divorced father of three. Sources said his dog was also found dead in the harbor.

A 24-year-old Boston woman was named a "person of interest" in a "suspicious" Charlestown houseboat death during her court appearance on domestic violence charges Tuesday.

A Boston woman was charged with murder Friday in the stabbing death of a man whose body was found attached to weights and wrapped in duct tape on a houseboat in Charlestown.
