Rebecca Coriam was last seen on the Disney Wonder last Monday — 24 hours after it set sail from Los Angeles in the US for a week-long cruise along the Mexican coast.
She didn’t show up for work the next day and hasn’t been seen since.
The 24-year-old, from Chester, was working as part of a youth programme on the 1,000ft-long £580million boat.
Pretty Rebecca was spotted on the ship’s CCTV making a phone call at 5am — shortly before she disappeared.
Passengers on the boat — which carries 2,500 passengers and a further 1,500 staff — were told Rebecca was missing and asked to be vigilant, but so far not trace has been found.
A source at the cruise company said the ship had been searched repeatedly.
The source added: “She went missing before the ship had docked at the first port of call, Cabo San Lucas.Quantcast
“At the moment there are three possibilities – that she accidentally fell overboard, that foul play is involved, or that she voluntarily went overboard.”
The Royal Bahamas Police force, where the ship is registered, are heading the investigation along with the US Coast Guard and the Mexican Navy.
