NORTH PORT, Fla. (WFLA) — North Port police officers and FBI agents resumed the search for Brian Laundrie Thursday.

Officers have searched Carlton Reserve for several days after learning from his family that he went missing Sept. 14. The Laundrie family told authorities that their son had left to go hike at the reserve, prompting the search.

There was more manpower on the ground Thursday than we’ve seen all week including 75 personnel from 16 different agencies.

“This is a tremendous, massive land. The more people, the more effective we are,” said Commander Joe Fussell with North Port PD.

Laundrie is the sole person of interest in the homicide investigation of his fiancé Gabby Petito, whose remains were identified Tuesday afternoon.

On September 22, 2021, the U.S. District Court of Wyoming issued a federal arrest warrant for Laundrie pursuant to a Federal Grand Jury indictment related to Laundrie’s activities following Petito’s death.

“While this warrant allows law enforcement to arrest Mr. Laundrie, the FBI and our partners across the country continue to investigate the facts and circumstances of Ms. Petito’s homicide. We urge individuals with knowledge of Mr. Laundrie’s role in this matter or his current whereabouts to contact the FBI,” wrote FBI Denver Special Agent in charge Michael Schneider.

North Port Police say the search at Carlton Reserve in Venice will pick back up Friday morning.
