Body found near Grand Teton confirmed to be Gabby Petito, death ruled a homicide

Officials have confirmed the body found over the weekend near Grand Teton National Park belongs to Gabby Petito, the 22-year-old woman who went missing while on a cross-country road trip with her boyfriend, the Teton County coroner said in a statement.

The initial determination is that she died by homicide, but the cause of death is pending final autopsy results, Teton County Coroner Dr. Brent Blue said.

Authorities had said a body "consistent with the description of" Petito was discovered in the Bridger-Teton National Forest in Wyoming on Sunday. At the time, a full forensic identification hadn't been completed and a cause of death was undetermined.

Petito's parents reported her missing on Sept. 11 after not speaking with her for two weeks. Her boyfriend, Brian Laundrie, was named a person of interest by police last week.

Petito, originally from New York, had left from Florida with Laundrie in a van in July for their trip, which they documented on social media.

On Aug. 12, police in Moab, Utah, responded to an "incident" involving the couple, but "insufficient evidence existed to justify criminal charges," Moab Police Department Chief Bret Edge said in a statement last week.

Petito was last seen leaving a hotel in Utah with Laundrie on Aug. 24. The next day, she spoke to her mother, Nichole Schmidt, informing her that their next stops would be Grand Teton and Yellowstone, Schmidt told ABC News, and that was the last time Schmidt talked to her.

On Friday, it was announced that Laundrie's whereabouts were unknown. His family told police they had last seen him last Tuesday. They said he had a backpack and told them he was going to the Carlton Reserve north of Laundrie's home in North Port, Florida, where he had gone for hikes before.

FBI Denver Special Agent in Charge Michael Schneider said in a statement that Laundrie has been named a person of interest.

"The FBI and our partners remain dedicated to ensuring anyone responsible for or complicit in Ms. Petito's death is held accountable for their actions," he said in a statement.
