brightcove.createExperiences(); The FBI has launched an investigation into the death of a 33-year-old mother who fell overboard off a Carnival cruise ship into the Gulf of Mexico at 2 a.m. Friday morning.
Samantha Broberg, 33, was sitting on a deck railing on the massive Carnival Liberty ship and tumbled backwards from the 10th deck into the water about 200 miles off the coast of Galveston, Texas, according to Carnival.
The mother of four from Arlington, Texas, had taken the four-day cruise from Galveston to Mexico with friends, Carnival has said. She was not reported missing to ship personnel by companions until Friday around noon.
Ship video footage confirmed her fall, Carnival has said, but the U.S. Coast Guard was not contacted until 5 p.m. on Friday after a ship-wide search was conducted. The Coast Guard called off its search for her on Sunday night.
The FBI’s coordination with Carnival is standard procedure in a case like this, Special Agent Shauna Dunlap, a spokesperson for the FBI’s Houston office, tells PEOPLE.
“We get called in whenever there is a death that occurs that is uncertain in how it occurred,” says Dunlap. “The FBI is coordinating with Carnival on an ongoing death investigation.”
A spokesperson for Carnival tells PEOPLE, “There is no foul play suspected here. Absolutely not.”
Dunlap of the FBI would not comment on whether foul play is suspected. “That will be answered by the ongoing investigation. Until we have a chance to complete a thorough investigation, we wouldn’t be able to comment at this time.”

Houston’s KPRC2 reported Monday that a passenger told the network that a blood stain was seen on the deck near where Broberg fell overboard and that a knife was found in the trash nearby. A reporter for the network showed a picture of the alleged stain on her Twitter account.
However, the Carnival spokesperson tells PEOPLE, “That is not a picture of blood. There was no blood found. There was no knife found. There is no suspicion of foul play. They are just rumors. We are getting a lot of inquiries about it and there is just nothing to it.”
Carnival does not know whether Broberg was intoxicated when she fell. “That information we don’t have,” the spokesperson says.
FBI notification and review “is a standard procedure in situations like this when there is a guest overboard, so that is nothing out of the ordinary,” the spokesperson says, echoing the FBI agent.
The U.S. Coast Guard suspended a search for Broberg on Sunday at 8:15 p.m. after spending 20 hours searching more than 4,300 square miles. The ship pulled into Galveston on Monday.
