Authorities were investigating the death of a man on Peddocks Island in Boston Harbor on Friday night, a State Police spokesman said.
Troopers responded at 9:35 p.m. to a call for medical assistance from the island, which is managed by the state Department of Conservation and Recreation, said the spokesman, David Procopio. He said a young adult male was pronounced dead at the scene.
The man apparently had sustained head injuries and may have gone into cardiac arrest, Procopio said, but an autopsy is needed to confirm that.
He said it was not known why the man was on the island, adding that is one question investigators will try to answer.
A spokeswoman for the department declined to comment, saying State Police had taken over the scene late Friday night.
The Boston Fire Department reported that some of its crews, as well as public safety officials from Boston Emergency Medical Services and the Hull Fire Department, also responded to the island Friday night.
According to the Boston Fire Department’s Twitter page, initial reports from the scene suggested that the man may have fallen into the basement of a quartermaster’s building because of a medical issue.
