A timeline of 22-year-old Gabby Petito’s case

Here’s what we know about the timeline in the case.

June 2021

Petito and Laundrie embark on a cross-country trip, according to North Port Police Chief Todd Garrison, who refers to Laundrie as Petito’s fiancé.

They planned to travel in Petito’s white Ford van to the West Coast and visit state and national parks across the western United States, Garrison says at a news briefing.

She had been excited to share her journey with her family and others on social media, he says.

“She maintained regular contact with her family members during her travels; however, that communication abruptly stopped around the end of August,” the police chief adds.

August 12

Moab, Utah, police have an encounter with the couple on August 12, where officers describe them as having “engaged in some sort of altercation.”

Although the two are described 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,” a report from officer Eric Pratt says.

At officers’ suggestion, the couple separated for the night, according to the report, which describes Petito as “confused and emotional.”

“After evaluating the totality of the circumstances, I do not believe the situation escalated to the level of a domestic assault as much as that of a mental health crisis,” Officer Daniel Robbins writes in the report. No charges are filed.

The couple each had their own cell phones in case of emergency, the report adds.

In a 911 audio recording from that day provided by the Grand County Sheriff’s Office, a caller tells dispatch he wanted to report a domestic dispute and described a white van with a Florida license plate.

The caller said as they were driving by, “the gentleman was slapping the girl.”

“Then we stopped,” the caller added. “They ran up and down the sidewalk. He proceeded to hit her, hopped in the car and they drove off.”

August 17

Laundrie flew to Tampa, Florida, from Salt Lake City on August 17, according to Laundrie family attorney Steven Bertolino.

Laundrie “flew home to obtain some items and empty and close the storage unit to save money as they contemplated extending the road trip,” Bertolino told CNN.

On August 23, Laundrie returned to Salt Lake City to rejoin Petito, the attorney said, adding, “To my knowledge Brian and Gabby paid for the flights as they were sharing expenses.

August 27

On August 27, a Louisiana couple vacationing in Jackson, Wyoming, said they saw Petito and Laundrie involved in a “commotion” as they were leaving the Merry Piglets Tex-Mex restaurant.

Nina Angelo, who was at the restaurant with her boyfriend, said Petito was in tears and Laundrie was visibly angry, going in and out of the restaurant several times and showing anger toward the staff around the hostess stand.

A restaurant manager told CNN she saw “an incident” at the restaurant August 27 but declined to give her name or describe what happened, and said the restaurant did not have surveillance video of the incident.

Last week of August

In a news conference in September, Petito family attorney Richard Stafford says the family’s last communication with Petito was August 30, but they do not believe the message they received was from her.

Stafford shares a timeline of events on September 17, as the family knows it:

In a series of videos posted on TikTok, Miranda Baker said she and her boyfriend picked up Laundrie that evening while he was hitchhiking in Colter Bay, Wyoming. Laundrie told them he had been camping at a site outside the Grand Teton National Park, near the Snake River, she said.

Once Laundrie found out Baker and her boyfriend were going to Jackson Hole instead of Jackson, he got agitated, asked that the vehicle stop, and got out near the Jackson Dam, according to Baker.

Baker said she spoke to law enforcement about the interaction. North Port police confirmed to CNN Baker spoke with the department before posting the videos on TikTok.

“Her account is plausible, it appears,” North Port police spokesperson Josh Taylor said. CNN has not been able to independently verify Baker’s claims.

Additionally, Norma Jean Jalovec, a seasonal Wyoming resident, told CNN she picked up Laundrie not far from Jackson Lake Dam on August 29 and gave him a ride to the Spread Creek dispersed camping area, where Petito’s remains were later found.

According to Jalovec, Laundrie told her he and his fiancée had a travel blog, she was in their van at the camping area working on the blog, and he had been hiking along the Snake River embankment for a few days. Jalovec said she later provided the FBI with that information.

Jalovec said when they arrived at Spread Creek, she dropped Laundrie off before the gate at the entrance of the camping area. She said she offered once or twice to take him farther, but he was insistent that he be dropped off at the entrance. Laundrie then offered her gas money, but she declined, she said.

Jalovec said she picked him up around 6:15 p.m., which was just a few minutes after Baker had said Laundrie had departed her vehicle.

September 1

Laundrie returns to the couple’s North Port home, where his parents also live, on September 1, according to police.

According to an affidavit attached to a search warrant request, a license plate reader shows the vehicle exited Interstate 75 into North Port at 10:26 a.m. ET.

The white vehicle Petito and Laundrie had been traveling in was later recovered by police at the home. It was processed and “there was some material in there” authorities will be going through, Taylor, the police spokesperson, says at a news briefing.

September 6

The Laundrie family goes to a campground about 75 miles away from their home in early September, according to county officials.

Roberta Laundrie, Brian Laundrie’s mother, was checked in at a waterfront site at the Fort De Soto Campground from September 6 through September 8, according to a Pinellas County Parks campground check-in report provided to CNN.

The Laundries were at the campground from September 6 to September 7 and left altogether, Bertolino later told CNN.

September 11

After not being able to get in touch with her, Petito’s family — who lives in New York — reports her missing to police in Suffolk County, New York.

North Port authorities go to Laundrie’s home that night and ask to speak to him and his family, but “we were essentially handed the information for their attorney,” Taylor, the police spokesperson, says.

“That is the extent of our conversation with them,” Taylor says.

September 16

In a letter read by the Petito family attorney at a news briefing held by police, the missing woman’s family begs for Laundrie’s family to help in the investigation.

“Please, if you or your family have any decency left, please, tell us where Gabby is located,” Stafford says. “Tell us if we are even looking in the right place. All we want is for Gabby to come home. Please help us make that happen.”

He says Petito’s family reached out to Laundrie’s family earlier in the month for information on Petito’s whereabouts, but his family refused to answer.

“We haven’t been able to sleep or eat, and our lives are falling apart,” the Petito family’s letter adds.

September 17

“We’ve been trying all week to talk to his family, to talk to Brian, and now they’ve called us here on Friday, we’ve gone to the home, and they’re saying now they have not seen their son,” Taylor tells CNN’s Chris Cuomo. “It is another twist in this story.”

Bertolino, the Laundrie family attorney, tells CNN “the whereabouts of Brian Laundrie are currently unknown. The FBI is currently at the Laundrie residence removing property to assist in locating Brian. As of now the FBI is now looking for both Gabby and Brian.”

In October, the Laundrie family attorney told CNN that upon further communication with the FBI, the parents now believe that Brian left to hike on September 13, not September 14.

“The Laundries were basing the date Brian left on their recollection of certain events,” Bertolino, the attorney, said on October 6.

September 18

North Port police say authorities are conducting a search for Laundrie at the Carlton Reserve, a nature area with more than 80 miles of hiking trails in Venice, Florida.

Roughly 50 law enforcement officers from five local agencies and the FBI are searching for Laundrie, Taylor, the police spokesperson, says at a news conference, adding Laundrie has an “enormous amount of pressure” on him to provide answers to what’s going on.

September 19

Human remains discovered in Teton County are “consistent with the description of” Petito, FBI officials say in a news conference.

“Full forensic identification has not been completed to confirm 100% that we found Gabby, but her family has been notified of this discovery,” says Charles Jones, FBI Denver’s supervisory senior resident agent in Wyoming.

September 20

The parents of Brian Laundrie are questioned at their home by the FBI.

Christopher and Roberta Laundrie are escorted from their home and return after federal agents executed a search warrant, according to Taylor, the North Port police spokesperson. Authorities search the home for hours.

Police say they have exhausted search avenues at the nature reserve and the search area has shifted.

September 21

“The cause of death remains pending final autopsy results,” the FBI says.

September 23

The warrant was issued pursuant to a federal grand jury indictment for the “use of unauthorized devices” related to Laundrie’s activities after Petito’s death, the FBI says.

Laundrie is suspected of using a debit card and PIN for accounts that do not belong to him for charges of more than $1,000 sometime between August 30 and September 1, according to the indictment.

October 12

After a detailed investigation by forensic pathologists, anthropologists and local law enforcement, with assistance from the FBI, Petito’s cause of death was determined to be strangulation, Teton County Coroner Brent Blue announces.

By Wyoming law, no other information apart from manner and cause of death will be released about the autopsy, Blue says at a virtual news conference.

The coroner says that Petito’s body was outside in the wilderness for about three to four weeks before being found.

Laundrie remains missing. Authorities have not explicitly connected him to Petito’s death.

October 20

Weeks into the search for Laundrie at Florida’s Carlton Reserve, investigators found what appear to be human remains along with personal items including a backpack and notebook belonging to Laundrie, FBI Tampa Division Special Agent in Charge Michael McPherson announced in an evening news conference on October 20.

The items were found in an area that had been underwater until recently, McPherson said.

“I know you have a lot of questions, but we don’t have all the answers yet,” McPherson added.

Laundrie’s parents informed the FBI and North Port police the night prior that they intended to come to the park to search for Laundrie, Bertolino says.

Law enforcement meets them there and after a “brief search” the family and law enforcement found articles belonging to him, the attorney adds.

The Sarasota County medical examiner and a cadaver dog were called to the Carlton Reserve area, CNN confirmed.

October 21

Earlier Thursday, Taylor, the police spokesperson, tells CNN what authorities found were “skeletal remains” as well as clothing believed to belong to Laundrie.

“It’s consistent with what he was believed to be wearing,” Taylor says.

Taylor indicates the items had been out there for some time.

A source with knowledge of the investigation also tells CNN’s Randi Kaye that the notebook discovered among other belongings is “possibly salvageable.”
