The 68-year-old professional fugitive finder has been on the hunt for Brian, and although he claims he's found clues, he hasn't located the 23-year-old "person of interest."
Dog didn't hold back, spewing accusation at Brian and his parents, Christopher and Roberta Laundrie, while speaking to WFLA reporter Josh Benson after the Teton County Coroner revealed Gabby Petito's cause of death was manual strangulation.
"The coroner's report isn't good for the entire Laundrie family," the reality star stated. "Brian's only chance is to turn himself in. He cannot run forever."
"The Laundries stonewalled Gabby's family because they knew what Brian had done and it looks like they've helped him run," Dog alleged. "And now it seems based on the report coupled with their behavior, they have more than likely acted and aided and abetting a murderer."
Dog continued by repeating, "Strangulation is not an accident" twice before stating, "It looks very bad right now for the Laundrie family."
Turning his focus to Brian, Dog ended his powerful message saying, "Brian, make a deal and turn yourself in now."
According to Benson, Dog never left Florida or the search for Brian despite his daughter claiming he bailed over the weekend after suffering an ankle injury.
"Dog also said he decided to stay in #Florida and had a ‘change of plans and couldn’t bring himself to leave,'" Benson tweeted. "He confirms he’s still on the search here in Florida."
Gabby's remains were found on September 19 in Wyoming near a campground that she and Brian were said to have visited. According to the coroner, her body was left outside for three to four weeks before it was discovered.
Her death was ruled a homicide. The cause of death was manual strangulation.
Gabby and Brian were on a cross-country trip to Wyoming when he returned home to his parents' Florida home on September 1 in their van without her.
Brian's parents announced he was missing on September 17 after allegedly going on a solo hike days before. Interestingly enough, a neighbor came forward alleging they saw Brian running from Christopher and Roberta's backyard on the same day they revealed he was gone.
The Laundries have remained tight-lipped, letting their lawyer do all the talking. According to their attorney, Christopher and Roberta have no knowledge of Brian's whereabouts.
