Officials believe a body found in Bridger-Teton National Forest in Wyoming, is missing 22-year-old YouTuber Gabby Petito.

An autopsy is currently underway, Teton County coroner Brent Blue confirmed to Fox News Digital. The body was found on Sunday by a search team with the aid of bloodhounds.

Authorities say the human remains fit the description of Petito, whose mysterious disappearance generated headlines all over the world.

The "Van Life" vlogger was last seen in August in Grand Teton National Park with her fiancé, Brian Laundrie, 23, who is considered a "person of interest" in her disappearance.

The couple traveled from New York to Wyoming on a cross-country road trip in August. Laundrie raised suspicion when he showed up alone in Petito's van at his parents' home in Florida on Sept. 1.

Police discovered Petito's 2012 white Ford Transit parked outside the Laundrie home on Sept. 11, after Petito's mother reported her missing.

Laundrie quickly lawyered up and refused to speak to police.

On Friday, Laundrie's lawyer reported him missing. However, Laundrie's family insisted he was "in hiding" due to the growing crowd of news media and curious onlookers outside the Laundrie home.

Laundrie was last seen at the home on Tuesday, Sept. 14.

Inside Edition aired police bodycam footage that shows a distraught Petito moments after a heated argument with Laundrie during their road trip in Utah.

A witness spotted the couple arguing at a grocery store and called 911. Police pulled the van over outside Arches National Park.

"We've just been fighting all morning," Petito said in tears in the bodycam video on August 12. The officer asked her to step out of the van and she complied.
 

 
"I just quit my job to travel across the country, and I'm trying to start a blog — a travel blog. So I've been building my website, so I've been really stressed," Petito said.

"She just gets worked up sometimes," said Laundrie who was observed with fresh scratches on his face.

Petito told the officer she was diagnosed with obsessive compulsive disorder. She said she feared Laundrie was going to drive off and leave her stranded at the grocery store.

Laundrie told the officer she scratched him when he pushed her hand away.

A family of travel vloggers believe they spotted Petito's van parked off the road in Grand Teton National Park on August 27, around the time it is believed Petito went missing.

Jenn Bethune shared footage of the van on YouTube. She spoke with Petito's mom who thanked her on Sunday for sharing the footage.

The video footage was the lead that prompted authorities to search the park for Petito.
