NORTH PORT, Fla. (WFLA) — Law enforcement agencies swarmed the home of Brian Laundrie’s family on Monday as the fiancé of Gabby Petito, who was identified by police as a person of interest in her disappearance, remained missing.

WFLA’s Christine McLarty was outside the Laundrie family home in North Port Monday morning and reported seeing about 15 FBI and North Port police units swarm and tape off the home around 10 a.m. ET.

“The FBI is executing a court-authorized search warrant [Monday] at the Laundrie residence in North Port, FL relevant to the Gabrielle ‘Gabby’ Petito investigation,” the FBI confirmed in a statement. “No further details can be provided since this is an active and ongoing investigation.”

Agents were seen going inside the Laundrie’s house carrying suitcases and documents. As WFLA’s Eagle 8 news helicopter flew over the scene, photojournalist Paul Lamison witnessed agents come out of the home to walk the perimeter of and photograph a shed in the backyard.

A tow truck arrived at the Laundrie home around 2:30 p.m. A Ford Mustang that has been in the driveway of the home for several days was eventually towed away.

The FBI concluded their search at the Laundrie home just after 6 p.m.

Earlier in the day Monday, North Port police announced they were no longer searching Carlton Reserve for Brian Laundrie, who was reported missing by his family on Friday. According to police, family members last saw him leave home Tuesday wearing hiking gear.

“At this time, we currently believe we have exhausted all avenues in searching of the grounds there,” North Port police PIO Josh Taylor said in a statement. “Law enforcement agencies continue to search for Brian Laundrie.”

Laundrie is the fiancé of Gabby Petito, who disappeared during a cross-country trip the two went on together this summer. Police say Laundrie returned home to North Port alone on Sept. 1 and was later named a person of interest in the missing person case involving 22-year-old Petito.
