The U.S. Coast Guard is searching the waters off Cuba for a woman who went overboard on a cruise ship hosting an electronic music festival.

As CNN reports, the Coast Guard says the woman fell from the ship 22 miles off the coast of the communist country.

The Norwegian cruise company that was transporting the festival said the act was not an accident.

"A female guest was observed intentionally going overboard while the ship was sailing in the Yucatan Channel," the company said in a statement. The cruise line says it sent out three rescue boats and notified the Coast Guard.

The incident happened on the first day of the cruise, which was travelling from Miami to Cozumel, Mexico.

Billed as the “Mad Decent Boat Party," the festival’s site promised extreme fun, sun and nonstop music.

“If you thought the first Mad Decent Boat Party was insane, then get ready to have your mind blown,” the advertisement reads.

As NBC News reports, the cruise line has offered their support.

"Both the ship and charter company teams are providing support to the family and all impacted guests during this difficult time," the company said.

The Mad Decent Boat Party festival is run by the Los Angeles record label Mad Decent, a label co-founded by DJ Diplo, who was also performing on the cruise.

Other artists onboard included Skrillex, Smalltown DJs, Dave Nada, and A-Trak.

If the Coast Guard recovers a corpse, this will not be the first time someone has died at an electronic music festival.

In 2011, a 19-year-old named Andrew Graf died after being taken to the Baylor University Medical Center from the Electric Daisy Carnival in Dallas, Texas.

As the Riverfront Times reports, Graf was one of multiple festival goers who were treated for drug, alcohol and heat-related illnesses during the musical event.
