Police in North Port, Florida, and Federal Bureau of Investigation (FBI) agents continued searching for Brian Laundrie, Gabby Petito’s fiance, on 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,” WFLA reported.

The North Port Police Department shared a clip of officers gathered to continue the operation:

However, Laundrie has not been charged with a crime, and authorities are handling his disappearance as a missing person’s investigation.

The couple had been traveling across the country over the summer and documenting the trip online, but Laundrie reportedly returned home to North Port on September 1 without the young woman, police said.

Fox 13 reported Wednesday divers working for an underwater recovery team were called to the 25,000-acre reserve where the search for Laundrie continued.

Aerial video footage showed officials assessing the area and retrieving gear from their vehicles:

Meanwhile, the body found Sunday near a Wyoming national park belonged to Gabby Petito, the Teton County Coroner confirmed in a statement:

“Teton County Coroner Dr. Brent Blue said the initial determination of Petito’s body is that her death was a homicide. Final autopsy results have not yet been released,” Breitbart News reported Tuesday.

FBI Denver announced Sunday that officials discovered a body in the Bridger-Teton National Forest that was “consistent with the description of” Petito.
