A cruise ship turned into a potential crime scene Friday after docking in Boston with two dead passengers, though authorities later announced that they had not found evidence of foul play.

Police responded to the Black Falcon Cruise Terminal after the Norwegian Cruise Line ship docked at 6:30 a.m. on Friday. The two passengers died Thursday, but their deaths are not considered connected.

Massachusetts State Police said Friday afternoon that one of the passengers was a 67-year-old woman from Rhode Island who appeared to have died of an apparent medical condition. The other passenger was a 23-year-old man from New Hampshire, and his death is not being considered suspicious.

No names were released.

The FBI assisted in the investigation because the deaths occurred outside state waters, MyFoxBoston.com reported.

A message was left Friday with Miami-based Norwegian Cruise Line.
