After an "extensive" search of the ship by cruise employees, McGrath wasn't found.

Angel Rodriguez, a detective with the Miami-Dade Police Department told Fox News Digital that McGrath was supposed to meet the family for breakfast before leaving the cruise but never arrived.

The detective also said that the ship’s cameras and security devices didn't indicate he went overboard.

The 26-year-old was on a two-night cruise to Bimini, Bahamas.
