Gabby Petito Case: 'Dog the Bounty Hunter' Hands Potential DNA Evidence To Authorities Amid Laundrie Dragnet

Dog the Bounty Hunter has reportedly turned over potential evidence to authorities with hopes it can be examined for DNA to prove 23-year-old fugitive Brian Laundrie’s presence on an island near a Florida park where he recently camped with his parents.

According to Duane "Dog" Chapman's team, the TV personality handed over some items he found after days of working on alerts from the public that Gabby Petito's former fiancé was traversing the Appalachians, the New York Post reported.

“Tracking a fugitive is a marathon, not a sprint,” Dog, who has had an off-duty cop embedded in his team, said. “We are continuing to search for Brian Laundrie. The longer he is on the run, the more dangerous this becomes.”

Public records have since confirmed that the Laundrie family had been to a campsite at Fort De Soto Park and that the fugitive’s mother, Roberta, checked into “Site 001-Waterfront” between Sept. 6 and Sept. 8, just days after Brian returned alone on a cross-country trip with Petito on Sept. 1.

On Sunday, his daughter, Lyssa Chapman, confirmed she has been in touch with witness Dennis Davis, an engineer who claims he had a conversation with Laundrie on a deserted road near the border of Tennessee and North Carolina just last Saturday morning.

The Chapman daughter noted she has been dealing with close to 3,000 tips that inundated the 833-TELLDOG hotline over the past week as the search continues around the unforgivable terrain of the Carlton Preserve.

Meanwhile, the Haywood County Sheriff's Office in North Carolina said on Monday that each call they receive on possible sightings of Laundrie is being heavily scrutinized by authorities, with the areas of concern and parts of the Appalachian Trail still being extensively searched, NBC New York noted.

Laundrie, 23, is a person of interest in the homicide case of his 22-year-old girlfriend Petito, whose remains were recovered by search crews in Wyoming on Sept. 19. He vanished nearly three weeks ago on Sept. 14 following an alleged visit to Fort De Soto Park with his family.

The man is now wanted on bank fraud charges after an unauthorized use of the dead woman's card to withdraw cash worth more than $1,000 during the period Petito went missing.

The FBI has since issued an arrest warrant after he was previously only wanted for questioning about Gabby's disappearance, according to Fox8.
