A 36-year-old woman who disappeared from a cruise ship last Friday is believed to have fallen overboard.

Jennifer Seitz of Winter Haven, Florida was in the midst of a seven-day holiday cruise of the western Caribbean when her husband reported her missing.

Crew members on the Norwegian Pearl searched the ship and the couple’s cabin for clues to Seitz’s whereabouts, and also contacted both the U.S. Coast Guard and Mexican Navy for help locating her.

The search reportedly turned up surveillance camera images showing someone falling overboard around 8 p.m. on December 25 when the ship was in waters off Cancun, Mexico.

When the ship returned to port in Miami on Sunday, FBI agents launched an investigation into the matter in order to determine if any crime occurred, or whether it was an accident.

Seitz’s husband is apparently under a certain amount of suspicion since he waited until 5 a.m. the next day to report his wife missing, and acted strangely nonchalant in the days after her disappearance.

Both American and Mexican ships and planes continue to comb a 2,500-square-mile area of ocean near where Seitz disappeared, but so far no trace of her has been found.

The other passengers on board the ship were unaware of the incident. Norwegian Cruise Lines officials said that no announcement was made because there was no public safety issue involved.

This incident marks the second time in a year that NCL has lost a passenger. In May a New Jersey woman disappeared from cruise to Bermuda.
