Glenn William Sheridan, 54, of Williamsburg, Virginia, disappeared from the Carnival cruise ship Celebration during a five-day Bahamas cruise and was reported missing when the ship returned to Jacksonville, Florida, on November 24, 2004. His wife, Gloria, last saw him at 1:30 a.m.; when she woke at 7:00 a.m. he was gone from their cabin. Ship records showed he did not disembark after docking.

Gloria suggested he might have fallen overboard as early as 4:00 a.m. while the Celebration was about thirteen miles off the northeast Florida coast en route to the St. Johns River. She described him as in good physical condition and a strong swimmer. A Coast Guard search with boat and helicopter covered about 350 square miles of ocean and river before being suspended; the Jacksonville Sheriff’s Office opened a missing person investigation and the FBI was kept informed. No trace of Sheridan was found and the circumstances remain unresolved.

Did anyone on the ship or who sailed that route in November 2004 see or hear anything that could help explain what happened to Sheridan?
