Authorities say a body discovered Sunday in Wyoming is believed to be Gabrielle “Gabby” Petito.

The FBI said the body was found by law enforcement agents who had spent the past two days searching campgrounds.

The cause of death not yet been determined, said FBI Supervisory Special Agent Charles Jones.

North Port Police confirm news that Gabby Petito has been found deceased.

Saddened and heartbroken to learn that Gabby has been found deceased. Our focus from the start, along with the FBI, and national partners, has been to bring her home. We will continue to work with the FBI in the search for more answers.

Jones said investigators are still seeking information from anyone who may have seen Petito or Brian Laundrie around some camping sites located on Grand Teton National Park’s eastern boundary, the same site that was the subject of a law enforcement search efforts over the weekend.

Petito and her boyfriend, Brian Laundrie, left in July on a cross-country trip to visit national parks in the U.S. West. Police said Laundrie was alone when he drove the van back to his parents’ home in North Port, Florida, on Sept. 1.

Laundrie has been identified as a person of interest in the case. He was last seen Tuesday by family members in Florida.
