fact, it was a homicide that led to gabby's death.waiting for that full autopsy report to be released from the coroner's office in wyoming to find out exactly how gabby was killed. but the family has been given the conclusion that this is, in fact, gabby and it was a homicide that led to her death in wyoming now more than three weeks ago. >> vaughn hillyard, thank you so much for that. petito's conference is all too common. the fbi last year declared near 55,000 people missing under involuntary circumstances. that's where they may be in danger. ten times that many went missing overall. nearly 40% of them, people of color. and in wyoming alone, hundreds of indigenous women and girls have disappeared, all garnering little or no attention. but petito's case has created an enormous following, galvanizing thousands of online sleuths who follow every development, come up with scores of theories, even post what they say the new evidence. joining me now, todd shipley,
