The FBI is investigating the death of a woman who allegedly fell off a cruise ship.

The 59-year-old woman, who has not yet been identified, was found off the coast of Massachusetts on Friday. The cause of death remains unknown, the Boston Herald reports.

“We are deeply saddened by this loss, and our thoughts and prayers are with her family at this difficult time,” the luxury boat company, Seabourn, said in a statement shared via email with PEOPLE.

The 650-ft ship known as the Seabourn Quest was on its way to Bar Harbor, Maine, from Boston when the woman was reported to have gone overboard at around 7 p.m. on Friday. “The ship immediately slowed and began search and rescue operations, and informed the United States Coast Guard,” the statement reads.

The Coast Guard found the woman’s body around 8:30 p.m., approximately 10 miles off Cape Ann, it said in a press release.

“We searched with multiple assets and with partner agencies by sea and air for the woman,” Petty Officer 3rd Class Stephen Leavitt, a watchstander at Sector Boston’s command center, said in the release, citing various groups that joined the search efforts, including the Rockport Harbormaster, which recovered her body.

Calls by PEOPLE to the FBI in Boston were not immediately returned. An FBI spokeswoman previously told the paper the agency was awaiting the results of an autopsy.

The Coast Guard authorized the Seabourn Quest to continue on its trip late Friday night, the Boston Globe reports.
