The warrant was issued for the ‘use of unauthorized devices’ related to his activities following the death of his fiancée, Gabby Petito

“We’ve deployed numerous resources, and we are trying to cover every acre in this preserve,” North Port Police Commander Joe Fussell said in a video shared Wednesday by the department.

Meantime, a small crowd gathered Wednesday night in Salt Lake City to mourn the 22-year-old, whose death has captured the attention of people nationwide.

“We won’t forget about you. We won’t let your light dim,” vigil organizer Serena Chavez said before the group.

“She’s not just a name. She’s not just a case. She was a person, and she was very special to a lot of people and many of us here,” the restaurant’s general manager, Lara Witschen, told WWAY. “She was a good soul, a good spirit, and touched so many lives. That’s what we want her to be remembered for.”

A small memorial now also marks the spot in Wyoming where Petito’s remains were found this week. Petito’s stepfather, Jim Schmidt, left a memorial at the site and sunflowers, “which were his daughter’s favorite flower,” family attorney Rick Stafford told CNN.

Laundrie’s neighbor last saw him weekend of Sept. 10

A neighbor who lives directly across the street from the home Petito shared with Laundrie and her family told CNN the last time she saw Laundrie at the North Port, Florida, home was the weekend of September 10.

Karyn Aberts said she saw Laundrie and his family “in the neighborhood out in the front yard,” saying it looked like “a normal … they were going for a walk kind of thing,” and that she “never thought anything about it.”

Aberts told CNN outside her home that she’d watched Petito and Laundrie converting the van they eventually drove across the country. (Officials would later find that van, a white Ford, at the Laundrie home.)

“They seemed to be sitting and laughing in their car and then the van that they were working on,” Aberts said, noting the last time she saw Petito was early in the summer, before the coupe left on their road trip.

Asked if she ever saw anything odd between Petito and Laundrie that would have been a red flag, Aberts said no.

Overall, Aberts described the Laundrie family as “very nice people.”

“We saw them take walks as a family,” she told CNN. “We saw them ride their bikes as a family and things like that.”

Witness says she saw a ‘commotion’ involving the couple

It also has spurred people to come forward with accounts of Petito’s last days.

Nina Angelo and her boyfriend, Matt England, saw a “commotion” last month as Petito and Laundrie were leaving The Merry Piglets Tex-Mex restaurant in Jackson, Wyoming, she told CNN Wednesday.

Petito was in tears and Laundrie was visibly angry, going into and out of the restaurant several times, showing anger toward the staff around the hostess stand, Angelo said. The couple’s waitress was also visibly shaken by the incident, said Angelo, who told CNN she did not see any violence or physical altercation between Petito and Laundrie.

A manager at The Merry Piglets, who declined to give her name, did see “an incident” at the restaurant on August 27 and called the FBI on Wednesday, she told CNN. The manager declined to describe what happened and said the restaurant did not have surveillance video of the incident.

And in a series of videos on TikTok, Miranda Baker said she and her boyfriend gave Laundrie a ride on August 29 in Wyoming — and that he claimed he was camping by himself for multiple days while Petito was back at their van working on social media posts.

Baker said they picked up Laundrie while he was hitchhiking in Colter Bay, Wyoming, which is not far from where Petito’s remains were found. He offered to pay $200 for the ride before he even got in the car, she said.

911 call of a domestic dispute

Evidence from a 911 call about a “domestic dispute” involving Petito and Laundrie shows the couple’s volatile relationship was not as aspirational as their sun-drenched lives on Instagram and YouTube suggested.

A man who saw the domestic dispute between Petito and Laundrie in Utah last month said, “They were talking aggressively at each other, and something seemed off.”

In a handwritten sworn statement, the witness said it appeared the two were arguing over control of Petito’s phone. “At one point she was punching him in the arm and/or face and trying to get into the van.” The witness’s first name is Chris and last name was redacted in the document provided by Moab City Police to CNN.

The witness said he heard Petito say, “Why do you have to be so mean?” although Chris added that he couldn’t be sure if the comment was meant to be taken seriously.

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 of police, the couple separated for the night, the report said, which described Petito as “confused and emotional.”

A National Park Service ranger who also responded to the call spent about 90 minutes with Petito and warned her that her relationship with Laundrie had markings of a “toxic” one, the ranger told the Deseret News of Utah.

“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.
