On Monday evening, the Federal Bureau of Investigation (FBI) announced it had concluded its search of Brian Laundrie's house via the official FBI Tampa Twitter account.
The FBI determined the Laundrie home to be a crime scene on Monday and required that his parents leave the residence as agents conducted the search.
The search came a day after authorities found a body near Grand Teton National Park matching the description of Laundrie's fiance, 22-year-old Gabby Petito, who has been missing since September 11.
The autopsy results for the body are expected to be announced on Tuesday, according to a statement Teton County Coroner Dr. Brent Blue made to CNN.
Petito and Laundrie set out from New York on a cross-country road trip in a van on July 2 and posted about the trip on social media along the way. On September 11, Laundrie returned home to Florida without Petito. On September 15, police said Laundrie was officially a person of interest in Petito's disappearance.
Police said Petito and Laundrie got into a fight in Moab, Utah on August 12, about a week before she was last seen.
The couple has been together since 2019 and got engaged in 2020, Petito's Instagram page shows.
Laundrie's current whereabouts are unknown, according to a statement made by his family attorney. Authorities have said he could potentially stay hidden in the swamps of Florida, his home state, for months.
The FBI has declined to comment on other details as the investigation is ongoing and did not immediately respond to Insider's request for comment.
