Authorities, including the FBI, swarmed the Florida home of Brian Laundrie's family Monday and removed his parents from the residence, declaring the house a "crime scene" a day after a body believed to be Laundrie's fiancée, Gabby Petito, was found.
"The FBI is executing a court-authorized search warrant today at the Laundrie residence in North Port, FL
Police on Monday declared a "crime scene" at the North Port, Florida home where Laundrie and Petito lived with the man's parents, Fox News reported.
As authorities cordoned off the area and put up yellow police tape at the scene moments before the FBI arrived, cops told people, "You're in a crime scene," according to the news outlet.
Reporters at the scene reported seeing Laundrie's parents being led out of the home by authorities and placed in a van at the driveway of the home as authorities searched the residence.
Laundrie remains missing after his parents told authorities on Friday that the 23-year-old left to go on a hike at the nearby Carlton Reserve earlier last week and never returned home.
Florida police said earlier Monday that they have "exhausted all avenues" in searching the sprawling grounds of the 25,000-acre Carlton Reserve for Laundrie and that authorities have no plans to conduct "a major search" there on Monday.
The latest development in the case comes after authorities said Sunday that they found a body at a campsite near Wyoming's Grand Teton National Park believed to be Petito. An autopsy to confirm the identity of the remains will be conducted Tuesday.
The discovery of the human remains was made more than a week after the 22-year-old woman was reported missing by her family in New York.
Laundrie was named by police as a person of interest in her disappearance after the couple went on a cross-country road trip out west to national parks in a white converted camper van on July 2.
He returned home to Florida with the van and without Petito on September 1, police have said.
