The deaths of two passengers abroad a Norwegian cruise ship that docked in Boston on Friday morning were not caused by foul play, said Massachusetts state police and FBI agents.

Experts examined the bodies of a 67-year-old woman from Tiverton, R.I., and a 23-year-old man from Littleton, N.H., and found they had not been murdered aboard the cruise ship, news agencies reported.

The dead were not together and their deaths were unrelated.

The decedents were among separate parties and their deaths were not related to one another, said a statement from the Suffolk district attorney's office. In the absence of criminal charges, no further details will be released, the release added.

The ship was returning to Boston after a seven-day cruise to Bermuda when the deaths happened.
