Authorities are investigating the disappearance of an Ohio woman who was reported missing Monday from a Carnival Cruise Lines ship.
The 36-year-old woman, whose identity was not released, had been on a four-day cruise to Key West and Mexico.
The Miami-based cruise line said relatives last saw the woman early Sunday but did not report her missing until Monday, when the ship returned to Miami. FBI spokeswoman Judy Orihuela said, however, that she was not aware of any delay in reporting the disappearance.
