On Friday, the captain announced a woman on the ship was missing. 11 News confirmed her name is Vonnie Ales, a Fort Bend County resident taking the cruise with her husband and three children.
Carnival said Ales' husband had last seen her Friday morning at 6:45 leaving their cabin as the ship passed near Cozumel. He reported her missing at 11 a.m. that morning.
The company also said a passenger claimed to had seen Vonnie Ales in an upper deck area 30 minutes later.
Several passengers said they visited with Vonnie Ales during the cruise and she seemed fine. But they also said Ales mentioned she had epilepsy.
"She had some medicine that would make her really tired, and she would fall asleep for about a day and a half to two days," said Samantha Yanelli, passenger.
But whether that had anything to do with the mystery of Ales' disappearance remains unknown.
