US Coast Guard authorities have halted the search for a woman who reportedly went overboard on a cruise ship near Ensenada, Mexico. Authorities searched more than 31 hours for the woman before pausing the search on Sunday pending additional information.

The woman whose identity has not yet been released is believed to have fallen from the fifth-floor balcony of her stateroom early Saturday.

The Carnival Miracle was returning Sunday to the port in Long Beach, where federal authorities were waiting to investigate, KABC-TV reported.

CBS Los Angeles reported that Daniel Miranda, a firefighter paramedic on the cruise told reporters he had assisted crews with their search for the woman on Saturday morning and that, “there’s some high suspicion of foul play.”

In a statement issued on Saturday morning, Carnival Cruise Line told CBS: “We advised Carnival Miracle guests this morning of an overboard incident involving one of our guests from the balcony of her stateroom…Our thoughts are with the guest and her family and our care team is providing support.”
