The FBI announced Sunday night that the body found earlier that day in Wyoming's Grand Teton National Park matches the description of Gabriele "Gabby" Petito.
The cause of death is not yet known.
The 22-year-old went missing while on a road trip with her fiancé, 23-year-old Brian Laundrie.
In July, Petito and Laundrie drove their van to several national parks in the United States.
They reported on their journey on YouTube and Instagram.
On September 1, Laundrie returned home in the van, without Petito.
Ten days later, her parents reported her missing.
On August 12, the two were put on the side of the road by the police.
Petito said she suffered from an anxiety disorder and indicated that she and Laundrie had had a fight.
Laundrie refused to speak to authorities.
He disappeared a few days ago after being identified as a suspect.
He is still being sought.
The search in the Carlton reservation in Florida turned up nothing on Sunday afternoon.
