Officials said human remains that match the description of Petito were found earlier Sunday. However, FBI officials say full forensic evidence has not been completed so they can’t definitively confirm that they’ve found her.
The cause of death has also not been determined, officials said.
For now, an undeveloped camping area on the east side of Grand Teton will remain closed as the investigation continues, according to the FBI.
Investigators are still asking anyone with more information on Petito or Laundrie, or if they had seen them around camping sites at the park, to let them know to help further the investigation.
Petito, 22, and her boyfriend Brian Laundrie left in July on a cross-country trek in a converted van to visit national parks in the U.S. West. Police said Laundrie was alone when he drove the van back to his parents’ home in North Port, Florida, on Sept. 1.
Petito’s family filed a missing person’s report Sept. 11 with police in Suffolk County, New York.
Laundrie has since been identified as a person of interest in the case.
