Brian Laundrie's parents were reportedly caught on video going into a Florida campsite with their son in their car but left without him —just days before Gabby Petito was reported missing.
According to the professional fugitive finder, he received a tip claiming Brian and his parents, Christopher and Roberta Laundrie, went camping at Fort De Soto in Pinellas County in early September.
Dog tells Fox News that the tip checked out. The TV personality claims the family took two trips to Fort De Soto on September 1-3 and, again, on September 6-8.
This is where he drops the bombshell.
Dog alleges three people entered the park, but only two came out during the family's second trip.
“They were registered, went through the gate,” he said. “They’re on camera. They were here.”
"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," Dog added.
Brian's parents have denied any involvement in their son's disappearance after revealing he went missing on September 17. According to Christopher and Roberta, Brian decided to go on a solo hike in the Carlton Reserve and never returned.
The FBI and local law enforcement launched a manhunt for Brian, keeping their focus on the Carlton Reserve — a place that a local man says Brian has a zero percent chance of surviving in.
They have since "scaled down" the search at the 25,000-acre swampy nature reserve, and Dog strongly believes the missing "person of interest" in Petito's murder might be at Fort De Soto.
Dog joined the manhunt for Brian over the weekend, but Roberta didn't welcome him with open arms. Dispatch audio reveals Brian's mom actually called the cops when Dog knocked on her home, offering his help to find her missing son.

Brian and Gabby — who lived at the Laundrie home in Florida — were on a cross-country trip heading to Wyoming. She was reported missing by her family on September 11, 10 days after Brian returned to his parents' residence without her.
The last time Gabby was seen alive was August 27, when patrons witnessed an "incident" between the couple at a Wyoming diner.
On August 26, a man claims he had a confrontation with Brian at a bar in Montana. According to him, Brian was there all by himself and "mad at the world," cussing out Republicans and "stupid southerners."
Gabby's body was found on September 19 in Wyoming. She was laid to rest over the weekend.
An arrest warrant has been issued for Brian after the FBI revealed he used an "unauthorized Capital One Bank card between August 30 and September 1, pulling out more than $1,000."
