FBI Houston says it is responding to “a suspected homicide that occurred on the MSC Seascape.” The cruise ship left Galveston on Sunday for a seven-day trip and came back on Monday. Officials have not identified the person who died or announced any arrests, the Houston Chronicle reported in a story syndicated on Yahoo.
The case raises an old question about crime at sea: who gets to investigate and prosecute? The MSC Seascape flies Malta’s flag, not America’s. The answer turns on two facts officials have not released: where the ship was, and who was involved.
What the FBI and MSC have said so far
The FBI’s statement is short. “Since this is an ongoing investigation, we cannot provide additional details at this time,” it said, according to the Chronicle. A maritime liaison agent from the FBI’s Texas City office is working the case. That agent is coordinating with the Coast Guard, Galveston port police, Customs and Border Protection and the cruise line, ABC13 Houston reported. ABC News quoted the FBI as saying that is “customary with crimes aboard a cruise ship.”
MSC Cruises said authorities told the ship to return to Galveston after it reported “a guest incident aboard our ship.” The company said it was “cooperating fully with the investigation and providing support to those impacted.” The ship has since left port and resumed its planned itinerary, MSC told FOX 26 Houston.
The Chronicle puts the ship’s capacity at about 5,800 passengers. Authorities have not said when the death happened, where the ship was, or what the circumstances were. We don’t guess at any of those here.
A Maltese ship sailing from a Texas port
Every ship at sea flies one country’s flag, and that country’s law travels with it. The MSC Seascape (IMO 9843807) sails under Malta’s flag, its VesselFinder listing shows.
The UN Convention on the Law of the Sea sets the baseline. On the high seas, a ship is under the “exclusive jurisdiction” of its flag state, unless a treaty says otherwise (Article 92). Closer in, a coastal country controls a territorial sea of up to 12 nautical miles (Article 3).
Inside that band, coastal countries are asked to hold back on crimes aboard foreign ships that are only passing through. Article 27 has exceptions, though. A ship that has just left the coastal country’s port is one, and that country keeps its full right to arrest and investigate on board. Crimes whose effects reach the coastal country are another.
The US law that reaches a foreign-flagged ship
Federal criminal law follows Americans to sea through the “special maritime and territorial jurisdiction of the United States.” Congress defined it in 18 U.S.C. § 7, and paragraph 8 was written for foreign cruise ships.
It covers a foreign vessel on a voyage that departs from or arrives in the United States. The crime must be by or against a US national, and the reach stops where international law stops it. A Galveston round trip passes the voyage test. Nobody yet knows about the nationality test, because the FBI has not said who was involved.
The stakes are high. Under Section 1111 of Title 18, first-degree murder in that jurisdiction carries death or life in prison. We built the table below from the provisions linked above. It is a guide to the rules, not a ruling on this case.
| If the ship was… | Who can act | Legal basis |
|---|---|---|
| Docked in Galveston | United States | US territory |
| Within 12 miles, just out of port | United States and Malta | UNCLOS Art. 27(2) |
| High seas, US national involved | United States and Malta | 18 U.S.C. § 7(8) |
| High seas, no US national | Mainly Malta | UNCLOS Art. 92 |
Why the cruise line had to call the FBI
The FBI is the first call because of a reporting law. The Cruise Vessel Security and Safety Act of 2010 sits at 46 U.S.C. § 3507. It covers ships with room for 250 or more overnight passengers that embark or disembark people in the US.
Certain events trigger a call. They include a homicide, a suspicious death, a missing US national, kidnapping, serious assault and some sexual offenses. The owner must then phone “the nearest Federal Bureau of Investigation Field Office or Legal Attache” as soon as possible.
The line also files a written report to a Department of Transportation website. It keeps a crime log that the FBI and Coast Guard can inspect, and it must hold related video for at least four years.
Planes have a parallel federal jurisdiction. That was the question when a passenger on United Flight 1681 texted about a hijacking.
Four quarters of DOT cruise crime data
The same law makes DOT publish a quarterly count of these reports by cruise line. We added up its last four cruise line incident reports, from July 2025 to June 2026. DOT counts reports made to the FBI “without regard to the investigative status,” so these are allegations, not convictions.
| Quarter | All reports | Homicide | Suspicious death | Sexual assault, rape | MSC |
|---|---|---|---|---|---|
| Jul–Sep 2025 | 47 | 0 | 0 | 36 | 7 |
| Oct–Dec 2025 | 44 | 1 | 1 | 29 | 7 |
| Jan–Mar 2026 | 43 | 0 | 0 | 37 | 4 |
| Apr–Jun 2026 | 50 | 0 | 1 | 44 | 9 |
| Total | 184 | 1 | 2 | 146 | 27 |
Cruise lines reported one alleged homicide in that year, on Carnival, in late 2025. Sexual assault and rape made up 146 of the 184 reports, or 79%. A homicide report is rare in this data.
Federal visits to ships in Galveston are not. KPRC 2 reported in May 2025 that investigators boarded cruise ships there “nearly every week,” as passenger numbers hit records. The Coast Guard works far offshore too, as in its rescue of an 86-year-old sailor 460 miles off San Diego.
DOT’s latest report covers April to June 2026. A report of this case would land in its October to December 2026 count.
