The affidavit, filed by Florida police last week, offers new insight into what investigators have gleaned as they try to determine not only what happened to Petito but also the current whereabouts of the fiancé who returned to Florida this month without her.
Human remains that officials said are consistent with Petito’s description were found Sunday in an undeveloped camping area in Wyoming’s Bridger-Teton National Forest on the eastern edge of Grand Teton National Park.
An autopsy was underway Tuesday morning, and the FBI is expected to release the results later in the day, Teton County Coroner Dr. Brent Blue told CNN.
Before she vanished, Petito sent multiple text messages and had many talks with her mother via cell phone during her trip, Florida police wrote in an application filed last week for a search warrant for an external hard drive found in the couple’s van.
In those conversations, there “appeared to be more and more tension between her and Laundrie,” the affidavit reads. On August 27, Petito’s mother received one last communication from her daughter, which she called an “odd text,” the affidavit says.
The message read: “Can you help Stan, I just keep getting his voicemails and missed calls.” Because the text message referred to Petito’s grandfather as Stan, her mother was concerned that something was wrong, the warrant states.
Following that text message, Petito’s phone was no longer operational and she stopped posting anything on social media about their trip, the warrant says.
One more text came on August 30 that read, “No service in Yosemite,” but her family doubts she wrote it, Richard Stafford, an attorney representing Joseph Petito and her mother, Nichole Schmidt, said.
In the 911 recording from the Grand County Sheriff’s Office in Moab, Utah, a caller reports what he called a “domestic dispute” between a couple.
“We drove by and the gentleman was slapping the girl,” the caller says. “Then we stopped. They ran up and down the sidewalk. He proceeded to hit her, hopped in the car, and they drove off.”
Although the Petito and Laundrie are described in a police report as getting into a physical fight following an argument, “both the male and female reported they are in love and engaged to be married and desperately didn’t wish to see anyone charged with a crime,” Officer Eric Pratt wrote in the report.
At the suggestion by police, the couple separated for the night, the report said, which described Petito as “confused and emotional.”
“I was imploring with her to reevaluate the relationship, asking her if she was happy in the relationship with him, and basically saying this was an opportunity for her to find another path, to make a change in her life,” ranger Melissa Hulls told the Deseret News.
CNN has sought comment from Hulls.
FBI searches Laundrie’s home
The FBI on Monday searched the North Port home of Laundrie and his parents, removing many items over several hours.
Laundrie’s parents, Christopher and Roberta, were escorted from their home Monday morning so agents could execute a search warrant, North Port police spokesman Joshua Taylor told CNN. They were later taken back inside for questioning.
Investigators resumed their search there at 8 a.m. ET Tuesday, the Florida Fish and Wildlife Conservation Commission said.
North Port police on Tuesday announced they were resuming their search on the Venice side of the reserve after saying Monday they’d shifted their search away from the reserve, having “exhausted all avenues” there. Agents from the fish and wildlife commission were requested Monday afternoon, commission spokesperson Adam Brown said.
An attorney for Laundrie’s family, Steven P. Bertolino, said he would hold a news conference Tuesday, but later canceled the event. He said the FBI requested he not hold the conference.
Agents removed a number of items from the home Monday, and a Ford Mustang convertible was also towed away.
‘She touched the world,’ father says
Pathologists will conduct a full forensic examination of the remains found Sunday to confirm the identity, said Charles Jones, FBI Denver’s supervisory senior resident agent in Wyoming. Authorities also must identify the cause of death, he said.
Petito’s family has been notified of the discovery.
Laundrie family attorney Steven Bertolino called the news “heartbreaking,” adding, “The Laundrie family prays for Gabby and her family.”
Laundrie’s sister praised Petito for her relationship with Laundrie’s nephews, according to a statement to ABC News.
“Gabby was a fun and loving influence to ‘the boys’ as she always referred to them. We will cherish the time we spent with her,” Cassie Laundrie said.
