After an extensive search, Carnival crew members were unable to find McGrath on the ship. The U.S. Coast Guard and the Miami-Dade Police Department were later called to investigate and searched the ship and the water for the missing man but failed to locate him.

Surveillance systems and the U.S. Customs and Border Patrol did not find McGrath once passengers were disembarking the ship, Carnival said. Miami-Dade authorities also checked security cameras, none of which indicated that he may have gone overboard, Rodriguez said.

McGrath's whereabouts are still unknown.

McGrath is 5-foot-9 and 170 pounds and was last seen wearing a black T-shirt, black shorts and gray sneakers.
