A passenger aboard the MSC Seascape cruise ship has been charged with murder following the vessel's unexpected return to Galveston, Texas. The FBI is investigating the death of a woman discovered aboard the ship.

Authorities were alerted to the incident on Tuesday, prompting the cruise ship to alter its itinerary and head back to port. The ship had departed from Galveston on Sunday for a Caribbean itinerary.

Details emerged from an affidavit that revealed the suspect, identified as a passenger on the cruise, allegedly admitted to "snapping" before beating and choking the victim. The affidavit outlines the suspect's account of the events leading up to the discovery of the woman's body.

The investigation is ongoing, with the FBI taking the lead due to the crime occurring at sea and involving international waters. The MSC Seascape is operated by MSC Cruises.

While the affidavit provides some insight into the suspect's alleged confession, further details regarding the relationship between the suspect and the victim, as well as the precise circumstances of the assault, have not been fully disclosed by law enforcement.

Officials have not yet released the identity of the deceased woman, pending notification of next of kin. The nature of the fatal injuries sustained by the victim is also part of the ongoing investigation.

This incident marks a rare but serious event aboard a commercial cruise liner, raising questions about security protocols and passenger safety during voyages. Cruise lines typically have procedures in place for handling medical emergencies and criminal incidents at sea.

The MSC Seascape has resumed its scheduled operations after the necessary investigations were conducted in Galveston. Passengers aboard the ship at the time of the incident may be interviewed as part of the ongoing inquiry.
