Dog the Bounty Hunter has joined the search for Brian Laundrie, a missing suspect in Gabby Petito’s homicide case.

The 68-year-old reality TV star/bounty hunter was filmed Saturday outside the Laundrie family home in North Port, Florida, where he and his fiancée Petito had been living. Footage posted by NewsNationNow correspondent Brian Entin shows Dog—real name Duane Lee Chapman—scoping out the property before banging on the front door. 

After realizing no one would answer, Dog returns to his vehicle with his wife Francie Frane and is questioned about his visit.

“Can you tell us why you’re here, sir?” Entin is heard asking.

“Really now, c’mon. You know, okay?” Dog replies, before being asked if he has any tips. “I’m trying to get some.”

Dog then instructs anyone with information on Laundrie’s whereabouts to contact his team at 833-TELLDOG.
