Former 'America's Most Wanted' host discusses the Gabby Petito homicide case on 'The Story'.

– Brian Laundrie’s attorney Steve Bertolino tore into "America’s Most Wanted" creator John Walsh Thursday, the morning after the longtime TV host aired an ID channel special on the unsolved homicide of the Florida man's former fiancée, Gabby Petito.

In the special, Walsh speculated that Laundrie might be there, in the Bahamas or hiding out along the Appalachian Trail and alleged his parents may be helping him as he remains on the lam.

"I absolutely believe that his family is helping him stay on the run," said Walsh, who also hosts "In Pursuit with John Walsh" on ID.

"Dusty relics like that Dog and John Walsh need a tragic situation like this so they can clear the cobwebs off their names and give their publicity-hungry egos some food," Bertolino told Fox News Digital, also taking aim at Duane "Dog" Chapman, the reality TV star and real-life bounty hunter who entered the search for Laundrie late last month.
