Brian Laundrie's sister has shared photos of texts and postcards that Gabby Petito sent to her while on what could have been a fatal road trip with her boyfriend.

It comes after crews searching a national park in Wyoming found a body.

The body is said to match the description of Gabby Petito...

On September 11th, influencer Gabby Petitio was reported missing to police by her mother.

Petito had not been in touch with her family since late August when she and her fiancé Brian Laundrie were in Wyoming.

Laundrie returned to Florida on September 1st, without Petito.

He's been named as a person of interest in the case by the authorities.

The pair had been documenting their travels on social media.

But Petito had not shared a post to her Instagram account for 3 weeks now.

North Port police chief, Todd Garrison, issued a statement as the search for her whereabouts began.

"We are pleading with anyone, including Brian, to share information with us on her whereabouts in the past few weeks," said Garrison, as per the BBC. "The lack of information from Brian is hindering this investigation. The answers will eventually come out."

The van the pair had been sharing has been seized and searched for clues.

"Brian is also refusing to explain why he left Gabby all alone and drove her van to Florida. These are critical questions that require immediate answers," the Petito family said in a statement.

Petito's mom had revealed the final text she received from her missing daughter.

Nichole Schmidt said she received a message from her daughter's phone on August 30th reading "No service in Yosemite."

However, Schmidt does not believe this text was actually written by Petito. "The van was in Florida on the 1st [of September]. I think I can do the math," she explained to the New York Post.

Schmidt refused to comment on who she did believe had sent the message.

Police officers had also released bodycam footage from a month before Petito's disappearance.

The footage shows officers, in Utah, talking to Petito and Laundrie after they responded to a 911 call of a domestic incident.

The hour-long bodycam footage from August 12th has been released by Moab City Police Department.

It shows officers' interaction with the couple when they pulled over their white van outside Arches National Park in Moab.

The footage, obtained by ABC7, shows the officer separate the couple and begin to question them about what led to the 911 call.

During her conversation with the officer, Petito can be heard saying: "I have really bad OCD. I was apologizing to him saying I'm sorry I'm so mean.

"We've been fighting all morning. He wouldn't let me in the car before... He told me I needed to calm down."

The officer then sat Petito in the back of his patrol car before moving to talk to Laundrie.

Speaking with the officer, Laundrie said: "She just gets worked up sometimes, I try to distance myself from her. I locked the car.

"I said, 'Let's just take a breather.' She had her phone. I was trying to push her away to say, 'Let's just take a step back,'" he said while adding that Petito hit him with her phone.

As per ABC7, the incident was reportedly categorized by police as a "mental/emotional health break" rather than a domestic assault.

The couple reportedly agreed to spend the night separately instead of charges being filed with the police helping Laundrie to sort a hotel room while Petito remained with the van.

Throughout the search, the Laundrie family had remained very quiet in regards to Petito's disappearance.

However, last week Laundrie's sister, Cassie Laundrie, opened up in an exclusive interview with GMA where she insisted that she and her family "want Gabby to be found safe," ABC7 NY reports.

"Obviously me and my family want Gabby to be found safe," Laundrie said.

"She's like a sister and my children love her, and all I want is for her to come home safe and found and this to be just a big misunderstanding."

Despite the pleas for information and days of looking, the search for Petito had been unsuccessful...

Until yesterday.

On Sunday, authorities searching the Grand Teton national park in Wyoming discovered human remains.

In a news conference, FBI officials said that the remains are "consistent with the description of" Petito, CNN reports.

Charles Jones, an FBI agent based in Denver, said: "Earlier today, human remains were discovered, consistent with the description of Gabrielle 'Gabby' Petito."

"Full forensic identification has not been completed to confirm 100% that we found Gabby, but her family has been notified of this discovery."

Throughout the search for Petito, Laundrie has remained as a person of interest.

And that only heightened last week after Laundrie disappeared, causing police to start looking for him...

Laundrie left his family home on Tuesday morning with a backpack and did not return home, ABC7 reports.

The Laundrie family then went to Carlton reserve on Wednesday in search of Laundrie, where they spotted his car.

The following day, the family returned to remove the car from the reserve.

It was not until 3 days after Laundrie went missing that authorities found out.

But now, it has been revealed that when Laundrie's family went in search of their son, they found more than just his car...

They also found a note...

The note on the front of Laundries car was from...

The North Port Police Department.

As per ABC7, Steven Bertolino, the Laundrie family attorney, said that police had placed a note on Laundries vehicle asking for it to be removed.

However, the family saw the note but decided to leave the car in place overnight in case Laundrie returned for it.

Today, FBI agents stormed the Florida home of the Laundrie family.

Brian Laundrie's parents were hauled away from their home while FBI agents conducted a search of the house. The area was declared a crime scene just moments after authorities suspended the search for Brian in a nearby nature reserve, claiming they had "exhausted all avenues."

But all attention is now on Brian Laundrie's sister, Cassie.

Cassie shared photos of the final texts and postcards she received from Gabby before she was declared missing. WABC reporter, Kristin, shared these photos on Twitter.

Our thoughts and prayers are with the Petito family during this incredibly difficult time.
