A missing Disney Wonder cruise ship worker had sex with a male crew member in front of her female lover before she vanished, reports have claimed.
Rebecca Coriam, 24, disappeared six years ago during a stint as a nanny on board a Disney cruise ship as it sailed through Mexican waters, near Puerto Vallarta.
A police probe concluded the Brit had fallen overboard during a storm.
But her parents – Mike and Ann Corium, from Chester – fear their “beautiful” daughter may have been murdered.
And notes made by cops during their investigation after interviewing people close to Rebecca have now revealed claims she was involved in a bisexual love triangle, according to the Liverpool Echo.
The officer in charge quizzed both Rebecca’s American girlfriend and a male crew member from Central America, it was reported.
Notes from the interviews, handed by the British Foreign and Commonwealth Office to Rebecca’s parents, are said to claim her final movements centred on her sexual relationships with the pair.
The notes reportedly claim the trio were drinking beer and chatting before they all went together to the male crew member’s room.
The papers are quoted as saying: “(Male crew member) had sex with both. (American woman) left the room again to get beer.
“Came back and Rebecca and (male crew member) had sex.”
Superintendent Paul Rolle of the Bahamas reportedly noted the male crew member had a “very nonchalant attitude” when quizzed.
Cops had to “give him a warning” after he was “laughing and joking”, it was claimed.
Two of Rebecca’s pals previously claimed she could have been sexually assaulted before her death.
And her parents insist she would not have consented to sex outside of her lesbian relationship.
The original investigation, carried out by a lone Bahamian police officer, has been criticised as a “shambles” and has been said to be littered with faults.
Private investigator Roy Ramm, a former Cdr of Specialist Operations at Scotland Yard, told The Sun last year: “As far as I’m concerned this is a murder investigation until someone proves it’s not.”
He said the original probe was “very seriously flawed”.
And Rebecca’s local MP Chris Matheson, who has done his own research, added: “There has been a whole wealth of contradictory evidence.”
“I think a crime has been committed here and I want justice for my constituents”, he said.
Rebecca disappeared after joining the Wonder, her second cruise ship, as it travelled between Los Angeles and Mexico.
After the alarm was raised a search turned up no results and Mike, 63, and Ann, 59, were told the terrible news that their daughter was missing overboard later that morning.
Ann recalled the last time she spoke to her daughter the previous day: “It was a quick call and we said we would speak on Facebook on Tuesday.
“It was all a bit of a rush but she seemed fine — just normal Bex.
“As far as we know she had a normal day on Monday. She had a meal on the Monday night with her friends and everything was fine.”
After frantically flying out to LA, the distraught couple were told their daughter definitely fell overboard.
But ex-Scotland Yard sleuth Roy said: “It would have taken a 100ft wave to wash her overboard from where they claim she must have gone.
“But we know the sea conditions at the time were good.”
The last footage of Rebecca, taken from the ship’s CCTV, then emerged.
It was recorded at 5.45am on the morning of her disappearance. She is on her phone on the first deck and wearing what looks like men’s clothes.
She is seen tugging at them repeatedly and showing signs of distress.
One fellow crew member thought she was speaking to a friend while another said “there was no mystery” and that it was a fight with her partner.
That staffer added: “She was a lovely girl, with underlying sadness.”
Another friend believes Rebecca then made her way to the fifth deck because it was her favourite spot.
This private area was used by crew to relax and there is a wall more than 6ft high between it and the sea.
The pal thinks Rebecca simply clambered up to sit on the wall and accidentally fell from it, recalling: “She loved deck five. It’s where we always used to go.
“I bet she climbed on to the wall and sat on the ledge in a ‘I need to feel like I’m off the ship for a second’ way.”
But one unnamed friend of Rebecca’s, who saw her at around 2am yet was not interviewed by police, said: “To call this an ‘investigation’ is an insult.”
The Bahamas Police concluded Rebecca’s death was “not suspicious”.
According to US reports, Disney has made an out-of-court and undisclosed settlement with the family.
But Roy believes the family is still owed answers and that there should have been an inquest.
He said: “A coroner would call witnesses who could say what they saw that morning and give the family some kind of closure.
“For this young woman to have been discarded like flotsam or jetsam is a disgrace.”
