On Monday, authorities, including the FBI, invaded the Florida home Brian Laundrie and his family. They also removed his parents from their residence. This was just a day after Gabby Petito's body, believed to be Laundrie, was discovered.

"The FBI executed a court-authorized search order today at the Laundrie home in North Port, FL that is relevant to the Gabrielle ‘Gabby’ Petito investigation," the FBI Tampa office tweeted Monday.

Fox News reported that police declared Monday a crime scene at the North Port home of Laundrie and Petito, who lived together with their parents in Florida.

The FBI arrived just moments after authorities had already established a perimeter around the area and put yellow police tape on the spot.

WFLA-TV reported that approximately 15 FBI agents and North Port officers ran into the house.

Reporters on the scene claimed that they witnessed Laundrie's parents being taken out of their home by authorities. They were then placed in a van in the driveway while authorities searched the house.

Laundrie is still missing. His parents informed authorities Friday that Laundrie, aged 23, left for a hike at nearby Carlton Reserve last week. He never returned to his home.

Florida police stated earlier Monday that they had exhausted all avenues in their search for the sprawling Carlton Reserve for Laundrie on 25,000 acres. Authorities also said that Monday was not the day that they planned to carry out a "major search".

Authorities announced on Sunday that they had found a body in a campground near Wyoming's Grand Teton National Park. It was believed to have been Petito. A Tuesday autopsy is planned to confirm the identity.

The human remains were discovered more than one week after the woman, aged 22, was reported missing by her family from New York.

Police have named Laundrie as a person of concern in Petito's disappearance. The couple took a cross-country trip in a converted camper van, which was white, to the West and national parks on July 2.

Police said that he returned to Florida on September 1 with the van, but without Petito.
