People Editorial Guidelines Published on October 12, 2021 02:32 PM Share Tweet Pin Email Gabby Petito died from strangulation, a medical examiner announced in a press conference Tuesday. The full autopsy results come more than three weeks after her body was found in Grand Teton National Park, ending a grueling search for the 22-year-old woman, whose mysterious disappearance during a road trip with her fiancé sparked nationwide conversation. On Sept. 21, Teton County Coroner Brent Blue announced that Petito died by homicide, but further findings about her cause of death were not initially disclosed. Blue told members of the media on Tuesday that under Wyoming state law, he is unable to divulge many details of the autopsy. He declined to share whether Petito was manually strangled or if an item was used, however, he confirmed that her body was outside for three to four weeks.

Body Found in Wyoming Confirmed to Be Missing 22-Year-Old Gabby Petito, Who Died by Homicide Petito and her fiancé, Brian Laundrie, had embarked on a cross-country journey in July, traveling from Florida to New York in their white Ford van, then heading west. Petito documented their adventures on her YouTube channel and planned to start a blog about their new "vandwelling" lifestyle. The couple's travels appeared to be going well until late August, when Petito's mother, Nicole Schmidt, stopped hearing from her while she was staying in Grand Teton National Park. More than two weeks after their last conversation, Schmidt learned that Laundrie had quietly returned to his parents' Florida home without her daughter. Petito wasn't reported missing until Sept. 11, 10 days after Laundrie allegedly arrived back in Florida. On Sept. 15, he was named a person of interest in his fiancée's disappearance.

In Moab, Utah, about two weeks before she was last heard from, dispatchers received a 911 call about a domestic dispute involving Petito and Laundrie, in which the caller said "the gentleman was slapping the girl." Police located the couple and pulled them over, and their interaction — which lasted for more than an hour — ended in the officers suggesting that the two spend a night apart to get some space from one another. They drove Laundrie to a hotel for the night. The whole incident was caught on body cam footage that has since been publicly released. Utah Police Release Body Camera Video of Gabby Petito and Fiancé 2 Weeks Before Her Disappearance Another twist entered the case on Sept. 17, when police obtained a search warrant for an external hard drive in the van Petito traveled in. The police affidavit requesting the warrant, which was obtained by PEOPLE, claims that the final text Schmidt received from her daughter was "odd" — and it came days after their last verbal contact. According to police, the message read: "Can you help Stan, I just keep getting his voicemails and missed calls." The affidavit states that Schmidt told investigators Stan is Petito's grandfather, but that she doesn't usually refer to him by his first name, leading Schmidt to believe that something was wrong with her daughter. The day after Schmidt received the unusual text, Petito's phone was no longer operational, and she did not post anything on social media, authorities said in the search warrant affidavit, which was "not normal behavior for [Petito], and they became more worried about her."

For the first several days of Petito's missing person case, investigators say they tried unsuccessfully to speak with Laundrie and his parents. They were directed to the family's attorney, who had instructed his clients not to speak.

As of Tuesday, Laundrie has still not been located despite exhaustive searches in a Florida wildlife preserve, where he is believed to have gone hiking on the day that he vanished. Authorities have yet to name a suspect in Petito's disappearance and homicide.
