'20/20' REPORTS ON THE GABBY PETITO CASE, INCLUDING THE INTERNET SLEUTHS WHO HELPED CRACK THE CASE, AND LINGERING QUESTIONS ABOUT WHAT'S NEXT FOLLOWING DISCOVERY OF BRIAN LAUNDRIE'S REMAINS

'20/20' Airs Friday, Oct. 29 (9:01-11:00 p.m. EDT), on ABC

Gabby Petito and Brian Laundrie captured national attention when the two left for a cross-country adventure, but only Laundrie returned. Throughout their travels, the couple let others into their seemingly happy world via social media, but behind the cameras, a much darker story played out. Laundrie returned to his family's Florida residence, without his fiancé, and Petito's family demanded answers about her whereabouts. When Laundrie vanished, the attention intensified as internet sleuths who helped crack the case wide open investigated and theorized, garnering over one billion views on TikTok for #GabbyPetito. A two-hour "20/20" reports on the horror that unfolded in the beauty of Wyoming's Grand Teton National Park and the details leading to the discovery of Laundrie's remains last week, and poses lingering questions about what's next. Through interviews with Jim Winder, who is the former Moab, Utah, police chief, experts on body language, and legal analysts, the program breaks down the viral body camera footage from the couple's police stop in Moab, days before Petito disappeared. "20/20" features interviews with Miranda Baker, a young woman who gave a hitchhiking Laundrie a ride in Wyoming; Jenn Bethune, who found the couple's missing van and called the FBI; Jason Jensen, a private investigator and co-founder of the Cold Case Coalition who searched Grand Teton National Park with his cadaver dog; and Mykel Hawke, a retired special forces combat veteran and survival expert who takes "20/20" cameras through the dangerous swamps of the Carlton Reserve in Florida, where authorities found Laundrie's body. The program dives into why the Petito case went viral and the outcry for the same attention to be applied to the cold cases of others - especially people of color and indigenous women who have disappeared in the same area as Petito. "20/20" airs on Friday, Oct. 29 (9:01-11:00 p.m. EDT), on ABC.
