'Heartbreaking' update in Gabby Petito case

A body "consistent with the description of" Gabby Petito, the 22-year-old woman who went missing while on a cross-country road trip with her boyfriend, was discovered in the Bridger-Teton National Forest in Wyoming.

The FBI Denver, the National Park Service and law enforcement made the announcement during a news conference Sunday evening in Grand Teton National Park. Charles Jones, the FBI's supervisory senior resident agent, said that a full forensic identification hasn't yet been completed, but investigators did notify Petito's parents.

A cause of death was also undetermined. Jones declined to comment further on the investigation.

"We continue to seek information from anyone who utilized the Spread Creek Dispersed Camping Area between the dates of August 27 and August 30. Anyone that may have had contact with Gabby, or her boyfriend or who may have seen their vehicle in that area, please share any new information with the FBI," Jones said.

An attorney for the Petito family released a statement Sunday evening asking for privacy to grieve and also thanking the agencies that assisted in the search.

"Your tireless work and determination helped bring Gabby home to her parents," the statement said. "The family and I will be forever grateful."

North Port Police tweeted that it will be working with the FBI in its investigation.

"Our focus from the start, along with the FBI, and national partners, has been to bring her home," the department tweeted.

The Teton County coroner confirmed to ABC News on Sunday afternoon that the agency dispatched resources to a body found in the national forest. No further details were disclosed.

The development came as a search for Brian Laundrie, Petito's boyfriend, resumed in Florida.

Petito's parents reported her missing on Sept. 11 after not speaking with her for two weeks.

Laundrie had been named by police as a "person of interest" in Petito's disappearance. The 23-year-old Laundrie, who returned home more than two weeks ago without Petito and has refused to speak to police, has not been seen since Tuesday, according to law enforcement officials.

The Laundrie family attorney said in a statement Sunday evening, "The news about Gabby Petito is heartbreaking. The Laundrie family prays for Gabby and her family."
