Glenn Sheridan of Williamsburg, Va., was reported missing by his wife Thursday, after the Carnival Cruise Line ship Celebration docked.
The ship’s electronic exit and entry program showed that Sheridan had not left the vessel after the arrival, and a crew search of the boat came up empty, Carnival said.
The Jacksonville sheriff’s office was investigating the missing-person case, and the FBI office in the city said it was being kept informed.
