Duane Chapman is pulling out all the stops during his search for Brian Laundrie, including trolling.
Dog The Bounty Hunter recently joined in the hunt for Gabby Petito's fiancé, and he feels that he's closing in on the wanted man, claiming he's come across a makeshift camp sight on Shell Island off the coast of Florida that was used within the last few days.

One of the reasons for the confidence stems from an empty energy drink can found on the ground in the thick brush. Dog said on Instagram that the can showed "no rust or faded colors," which indicates it's relatively new.
However, the reality TV star and his team "found no conclusive evidence" that Brian was in the area.
While Dog and his team search the ground, a message is also being flown through the air. On Sept. 30, a small plane flew over the area carrying a banner that read, "Aloha Brian Laundrie —Dog."
While Duane, 68, was not behind the aerial message, he did post it to his Instagram to troll Brian.
"Frankly, I wish I had thought of that, but it wasn't our team," joked Dog. "I'd love to shake the hand of whoever is behind the banner, I'll tell you that."
In addition to the foot and air pursuits, Dog is also using social media to help and keep followers apprised of the hunt.
"This has been a very different search," Dog said. "Social media has enabled us to do this alongside everyone out there. America is along for the journey with us and I'm ready to do more!"
