She was captured by CCTV in the crew lounge earlier that morning, having a phone conversation with a woman that appeared to be causing her emotional stress.

The Coriam family have been supported by British government officials instituting policies allowing for more comprehensive investigations of such incidents in the future, and advocates for the relatives of many other crew and passengers who have been reported missing from cruise ships over the last decade.

Coriam undertook youth studies at Liverpool Hope University, then moved to the U.S. for four months to teach sports at Camp America in Maine.

[2] In June 2010, she went to London for a Disney Cruise job interview, then received training at the company's theme parks in Florida after being hired.

[3] At 9 a.m. Pacific Daylight Time that morning on the Wonder, off the coast of Mexico bound for Puerto Vallarta and Cabo San Lucas, Coriam had missed the start of her shift.

They claimed Disney kept them in a car with blacked-out windows and brought them on board via a rarely-used side entrance after all the passengers had disembarked.

Several crew members who had been on the ship at the time of Coriam's disappearance, none of whom wanted their names used, spoke to him and suggested that more was known about her fate than Disney or the Bahamanian police were publicly admitting.

[4] On the anniversary of Coriam's disappearance, her parents told the Liverpool Echo that they heard the names of a young woman and older man on the ship mentioned as possibly being involved in a love triangle with her, and called for them to come forward.

[4] However, Melissa was dismissive of the suggestion that the slippers allegedly found near the pool (which were included among the belongings returned to Coriam's parents) had been hers.

The Coriams said this led them to strongly doubt Disney's claim that they had been found in the pool area, as well as its theory that Rebecca was swept or fell overboard from there.

[11] It was also noted that in the video of the phone call, Rebecca's clothes appear much too big for her; her friends and fellow crew have speculated that they may have been someone else's.

[10] Former City of Chester MP Chris Matheson believes Coriam was the victim of a crime and was possibly sexually assaulted or murdered.

[12] John Anderson, a private investigator who has worked with both the Coriams and Matheson, says records show the seas around the Wonder were normal that night, casting doubt on Disney's "rogue wave" claim.

[10] He also called for laws that would allow British authorities to investigate their own citizens' deaths on cruise ships in international waters.

[12] Ronson reported that, at the time his article was published, the Coriams had received no further updates from Disney or the RBPF on the progress of the investigation.

[4] In November 2011, the Coriams' local MP at the time Stephen Mosley brought the case up in the House of Commons, telling Minister for Shipping Mike Penning that "the investigation into Rebecca's disappearance was appalling".

[13] He stated that the "Bahamian authorities made virtually no attempt at investigating Rebecca's disappearance" and said the RBPF was "internationally recognised as almost toothless [...] very few people know when they board a cruise ship that they are so poorly protected".

[4][13] Countries such as the Bahamas, often criticized for the lax standards of such "flag of convenience" ship registrations, did not have the investigative capabilities to deal with such incidents.

[4] Penning responded by announcing that the Marine Accident Investigation Branch would investigate all deaths or disappearances of British citizens from vessels anywhere in the world, paralleling similar legislation signed by U.S. President Barack Obama that gives the FBI the same authority in the event of the death or disappearance of any American citizen.

[13] Penning, too, was critical of Disney and said the company was "more interested in getting the ship back to sea than in investigating the case of the missing member of their crew".

[14] Kendall Carver, an American who founded the lobbying group International Cruise Victims after his own daughter's 2004 disappearance from the Celebrity Mercury, said, "In other corporations, police get involved.

"[4] Miami lawyer Jim Walker, who publishes the highly critical blog Cruise Law News, agreed; he commented on Ronson's article to say that "the Coriam family does not deserve Mickey Mouse games".

[15] Walker later represented the Coriams in a suit against Disney in American courts; they settled with the company in 2015 for an undisclosed sum and an agreement not to discuss the case publicly.

[10] Carver and Walker both believe Disney has more evidence than it has shown, particularly security footage of the area by the pool, and is covering up knowledge of what happened out of fear of adverse publicity.

"[4] Melissa told Ronson it was implausible that there was no footage since the pool is close to a number of other important offices housing sensitive documents, such as HR and payroll.

Their spokesperson refused to comment on specifics about whether a tape of the phone call or additional security camera video exists, stating, "We wish we knew what happened as much as anyone [...] Rebecca's disappearance has been difficult and heartbreaking for everyone.
