The man found dead on a Charlestown houseboat over the weekend has been identified as Joseph Donahue, 65. His death has been ruled a homicide.

Boston Police identified the man Wednesday and said that he was found suffering from multiple stab wounds and that the death was ruled a homicide. The announcement stopped short of announcing a suspect in the case and instead said that homicide detectives are actively reviewing the facts and circumstances surrounding the incident.

On Wednesday, Suffolk County prosecutor Amelia Singh described 24-year-old Nora “Andi” Nelson as a “person of interest” in the death, as she was found at the scene. Nelson was arrested on previous charges of domestic violence and assault of a police officer and was held on $7,500 bail. She has no charges connected to Donahue’s death at this time.

Police responded late Sunday night to a houseboat on Shipway Place in Charlestown where Donahue was found dead.

Police ask anyone with information on the incident to contact homicide detectives or to submit information anonymously through the CrimeStoppers tip line at 1-800-494-TIPS (8477) or by texting the word TIP to CRIME (27463).

This is a developing story.
