Teton County, Wyoming, Coroner Brent Blue has scheduled a news conference for Tuesday to talk about Gabby Petito’s autopsy.

Blue’s preliminary report on September 21 confirmed Petito’s identity and said the manner of death was homicide but withheld the cause of death for the final report.

Petito’s body was found two days earlier, in a remote campsite in Bridger-Teton National Forest, adjacent to Grand Teton National Park, after an intense eight day search.

Petito, 19, and her boyfriend, 23-year-old Brian Laundrie, set off on a cross-country van trip on July 2. For nearly two months, Petito kept in contact with her family — although she did not tell them about an August 12 traffic stop in Moab, Utah, after 911 callers reported seeing a potential domestic incident involving the two.

Moab police determine a sobbing Petito was the primary aggressor and put Laundrie up in a hotel for the night, leaving Petito with the van.

Petito’s family last heard from her during the last week in August, and then, without telling his girlfriend’s family, Laundrie returned to the Florida home he and Petito shared with his parents. He was driving the van, but Petito was not with him.

The Laundries ignored her family’s increasingly desperate requests for information, even after the Petitos filed a missing persons report on September 11. They also refused to speak with North Port, Florida, Police, who named Brian Laundrie a person of interest in the disappearance but repeatedly claimed they had no proof of a crime and could not bring him in for questioning.

Police also claimed throughout the week they knew “exactly” where Laundrie was, but on September 17, his parents called police to their home and told them he’d left the house earlier in the week and they hadn’t heard from him since.

Roberta and Chris Laundrie initially told police Brian had left on September 14, saying he was going hiking in the Carlton Reserve, a 24,000-acre nature preserve nearby that at the time was largely flooded. They later said they’d been mistaken, and their son left the house on September 13.

Law enforcement launched a search for Laundrie. Two days after his parents reported him missing, search crews in Wyoming found Gabby Petito’s body.

The FBI, which had joined the investigation by that time, presented evidence to a grand jury charging Laundrie with bank fraud for allegedly using Petito’s bank cards to withdraw money from her account after she was last heard from. The jury indicted him, and the FBI issued an arrest warrant for him.

The coroner’s news conference will be held at 12:30 p.m. MT (2:30 p.m. ET), according to KIFI.
