BOSTON — Authorities say they have recovered the body of a 21-year-old man who fell overboard from a cruise in Boston Harbor.

Massachusetts State Police say divers found the body near Peddocks Island around 1 a.m. Sunday.

Plymouth County District Attorney Timothy Cruz said the man has been identified as Aaron Dibella of Peabody.

Police say the man went overboard from the Provincetown II cruise ship shortly after 8:30 p.m. on Saturday.

Authorities say they are investigating how he fell into the water.

They say a security guard from the cruise ship went into the water to try to save the man but couldn't reach him.

Police say the man then went underwater and didn't surface again.

Officials say the Chief Medical Examiner will determine the exact cause and manner of the man's death.
