The search for Brian Laundrie has continued into its second week, with authorities providing the public with few strong leads and limited information about his possible whereabouts. According to police, Laundrie had returned to his parents' home in North Port, Florida, on Sept. 1 but details have been limited to searches that have come up short.

Laundrie, 23, remains a person of interest in the disappearance of his fiance Gabby Petito, whose death at a Wyoming national park was ruled a homicide. It's unclear if Laundrie, who traveled in a van in July with Petito throughout the Rocky Mountain region, is in the state of Florida.

On Monday, it was announced that the FBI officially took the lead in the search for Laundrie. He was reportedly last seen on Sept. 14 by his parents, who have not been cooperative with the search.

One of the main locations for the search has been the Carlton Reserve, a roughly 25,000-acre preserve in Sarasota County, Florida, but exhaustive searches have not yielded results.

Fox News has taken to frequently interviewing Duane Chapman, otherwise known as "Dog the Bounty Hunter."

Chapman has acted on a tip that Laundrie and his parents were camping at “Fort De Soto Historical Fort” from Sept. 1-3 and Sept. 6-8. This tip suggests that he could have been there instead of the Carlton Reserve "swamp," leading authorities away from his actual location for days.

"They were registered, went through the gate. They’re on camera. They were here," Chapman told Fox News Monday night. "We think at least if he’s not here right now, we are sure he was caught on camera as he went in the gate — that he was here for sure. Not over in the swamp."

Chapman told Fox News said he was informed that Laundrie's parents were seen leaving the campsite, but without Laundrie.

"Allegedly, what we’re hearing, is two people left on the 8th. Three people came in on the 6th, and two people left on the 8th. I think he’s been here for sure," Chapman said.

But Chapman's tip may not lead to Laundrie. The Pinellas County Sheriff's Office told a Fox affiliate in Tampa that there are no confirmed tips or sightings of Laundrie at Fort De Soto Park.

A post on Petito’s Instagram page showed Laundrie and her at the tagged location of Fort De Soto Park in February. Chapman, who has noted the Laundrie is an outdoorsman, said evidence could be found there.

One of the photos in the post shows Petito and Laundrie standing “behind bars.”

Some social media users have since commented on the post referring to the "coincidence" of the photo. “Wow he predicted his future,” one comment read. “This is exactly where you will end up,” another read, in reference to Laundrie. “He better get used to that view,” a third comment read.
