Dog the Bounty Hunter says he's not sharing his leads with law enforcement

Dog the Bounty Hunter, a reality TV star whose real name is Duane Chapman, said that he's received several useful tips connected to the murder of Gabby Petito. Her case has captured the nation after she disappeared while riding in a cross-country van trip with her fiancé.

"We're getting calls like crazy," he said. "I think the success of this bounty hunt is going to be the tip line."

Laundrie has been charged with using two financial accounts that did not belong to him between August 30 and September 1. No charges have been brought against him in the death of Petito, whose body was found in Wyoming's Bridger-Teton National Forest, CNN reports.

In an interview with the right-wing TV station, Newsmax, Chapman said, "We're right on his tail." He said his tipline, 833-TELLDOG, has advanced his investigation into the Petito case.

Chapman said he's received more than 2,000 calls, with 20% of them being positive leads.

Petito's death and the search for Laundrie has become an obsession for many, spurring digital detectives to comb through the couple's online trail and try to solve the case.

"It's very hard to remain missing when the world is looking for you, or just your family. It is really, really difficult today to remain intentionally missing," said Michelle Jeanis, an assistant professor at the University of Louisiana at Lafayette's Department of Criminal Justice who specializes in missing persons.

The hosts of Newsmax asked Chapman how his investigation differs from law enforcement's.

"We kind of do the same thing. But I really don't pay too much attention ... I don't call the police they are usually called on me," he said.

Laundrie returned to his parents' home in North Port, Florida, on September 1 without Petito, police said, and was home for about two weeks. His parents told authorities September 17 that they last saw him three days earlier.

Chapman said he's not coordinating with law enforcement officials on his independent investigation into Laundrie's disappearance.

Chapman claims he will capture Laundrie before his birthday on Oct. 18 or 19.
