The FBI is searching the Florida home of Brian Laundrie, the fiancé of 22-year-old Gabby Petito, a missing woman now believed to be dead.
Agents with a search warrant surrounded the property on Monday. Mr Laundrie’s parents were removed from the home but have since been allowed back inside.
On 1 September, Mr Laundrie, 23, returned home alone a month into a cross-country road trip with Ms Petito.
On Sunday, remains matching Ms Petito’s description were found in Wyoming.
Police consider Mr Laundrie a “person of interest” in the case but have not charged him with any crime. He declined to speak to police, and went missing a few days later.
Video from local media on Monday showed officers and FBI agents approaching the Laundrie home, some with guns drawn, cordoning it off with crime scene tape and placing Mr Laundries’ parents in an unmarked van.
In a tweet, the FBI confirmed it had secured a search warrant in court but added: “No further details can be provided since this is an active and ongoing investigation.”
