Police named Brian Laundrie a "person of interest" in the disappearance of 22-year-old Gabby Petito. Gabby's family reported her missing earlier this month on Sept. 11. Police said the couple was on a cross-country road trip when Brian returned home to North Port without her. Police believe he arrived home on Sept. 1.
On Sunday, The FBI announced authorities were searching the vicinity of Spread Creek Dispersed Camping Area in the Bridger-Teton National Forest. The search revealed human remains consistent with the description of Petito.
Full forensic identification has not been completed. Authorities have not announced a cause of death.
"The FBI and our partners extend our heartfelt condolences to Gabby's family and loved ones. This is an incredibly difficult time for them, and our thoughts are with them as they mourn the loss of their daughter," the FBI said in a press release.
The couple had been traveling across the country in a white van. North Port police recovered the van more than a week ago.
While the couple visited Utah, officers in Moab pulled over the white van on August 12. The Moab City Police Department responded to a call about a domestic disturbance between Gabby and Brian. The couple separated for the night, but no charges were filed. Moab Police released the 911 call where a witness said he saw the couple arguing.
"We drove by him, a gentleman was slapping the girl," said the caller in the 911 call.
Gabby's family said they last spoke to her by phone on August 25.
