The US Coast Guard has called off its search for Kevin McGrath, a 26-year-old Carnival Cruise passenger who disappeared during a family vacation to celebrate his father's 60th birthday. McGrath was reported missing by his family after he failed to show up to breakfast on the ship on Monday morning. The Coast Guard conducted an extensive search of the waters off the coast of Florida, covering 3,300 square nautical miles, but found no sign of McGrath and decided to suspend the mission on Thursday.

The cruise ship's cameras and overboard detection system did not indicate that McGrath went overboard during the cruise from Miami to the Bahamas, according to Miami-Dade police. An exhaustive search of the ship after it docked in Miami also turned up empty for the missing man. Surveillance systems, including US Customs and Border Patrol, did not detect him during the debarkation process. McGrath was with a large group of relatives on the three-day cruise and was last seen by his brother at around 2 a.m. on Monday. His keycard was used to enter his room at 3:30 a.m. However, when the family gathered for breakfast at 7:30 a.m., McGrath did not show up.

Danielle McGrath, Kevin's sister, described his disappearance as "so random, out of nowhere." She explained that McGrath's absence is completely out of character for him, and she has been playing different scenarios in her mind to try and make sense of the situation. She expressed her desperation and anguish, saying she hasn't eaten or drunk anything all day, and her eyes hurt from crying. Carnival Cruises is conducting its own investigation into McGrath's disappearance and has been reviewing closed-circuit video footage from the ship.

This incident comes just a week after another passenger, 19-year-old Sigmund Ropich, fell overboard from the world's largest cruise ship, Royal Caribbean's Wonder of the Seas, off the coast of Cuba. Ropich has yet to be found, and his disappearance remains a mystery.
