The BBC names the woman as 24-year-old Rebecca Coriam, a youth counselor from Chester, England.
According to Disney spokeswoman Christi Erwin Donnan, the crewmember was reported missing Tuesday morning when she failed to report for duty. Several thorough inspections of the ship were conducted, one as recently as Saturday.
The line's most recent statement says it has "been working with all of the appropriate authorities. Rebecca's disappearance has been difficult for everyone at Disney Cruise Line. We've been in close contact with the Coriam family, and we're assisting them in any way we can."
ABC News reports that Coriam's parents and aunt have flown to Los Angeles to meet the ship. According to the Coriams, Rebecca's roommate says Rebecca placed a phone call to a friend early Tuesday, just hours before failing to show up for her shift. According to the ABC report, the Coriams claim the line knows what the call was about, but it won't release details at this time due to the ongoing investigation. However, the Coriams say they aren't sure that Rebecca was ever on the ship at all and would like proof.
The line has been in contact with the F.B.I. and the Bahamian Maritime Authority, which is leading the investigation on this matter. (Disney Wonder is registered in the Bahamas, and so the flag state takes the reins in this case.) The Mexican Navy out of Cabo San Lucas is conducting a search along the ship's route. Authorities have also "spoken with the crewmember's colleagues to gather as much information as possible," according to another Disney statement.
Passengers who were on the cruise are discussing the issue on Disney forum DISBoards.com.
Disney Wonder was sailing a seven-night Mexican Riviera cruise out of Los Angeles. The ship was at sea Monday and Tuesday, when the crewmember went missing.
