Sean says Kevin was sharing a room on the ship with his twin brother Andre. That was the last time he was seen.
“He said he heard the door open anywhere from 5-7 (a.m.) because it’s dark in the room, and can’t really tell the time,” Sean recalled.
Kevin was supposed to meet his family for breakfast before the ship returned to Port Miami the next morning, but he never showed up.
“We went for breakfast at 7:30, and he didn’t show up," Sean told CBS12 News. "I asked his brother where he was, he said he didn’t come back to the room.”
Authorities say Kevin was not detected by any of the ship's surveillance systems. The ship's cameras and security devices do not indicate that McGrath went overboard, and that's what his father says makes his disappearance even more puzzling.
“His SeaPass card was not scanned, because when you exit the ship, you have to scan your SeaPass card, and we had his documents, like his birth certificate and driver’s license, so there’s no way he could come off the ship," Sean explained. "I was told from Carnival that they had sensors all around the ship, so if someone did go overboard, they would’ve been alerted, and nothing was alerted.”
