After weeks of speculation,  the announcement finally came. The Teton County, Wyoming, coroner, Dr. Brent Blue, released that Gabby Petito died by strangulation. Petito’s boyfriend Brian Laundrie quickly became a person of interest.  News broke of a domestic violence issue in Moab where Gabby was made to be the aggressor.  Brian Laundrie returned to his Florida home on September 1 without Gabby, but with the converted camper van the couple had been traveling in on their cross-country road trip. He used Gabby's money to fund his cross-country drive back. No one told the Petitos where their daughter was or where she went missing.  Then Brian Laundrie went missing himself. His remains were later found after he committed suicide, still with no news about Gabby.

Questions arose about what parents Chris and Roberta Laundrie knew about Gabby's disappearance and then death. The Laundries  were the subject of a civil lawsuit filed by Gabby Petito's parents, who alleged that the Laundries inflicted emotional distress by acting with knowledge of Petito's death and the location of her body, which the Laundries denied. In depositions related to the lawsuit, Brian's parents admitted Brian told them Gabby was "gone" and that he needed a lawyer, while denying they knew she was dead.  Gabby's dad Joe, and stepmom, Tara, joined Nancy Grace at Crime Con 2025 and in the studio, to discuss  how the Petitos learned of their daughter's death, as well as how they have dealt with the knowledge that Brian Laundrie's parents reportedly knew Gabby was dead and did not share the information.  The Petitos also share about their latest philanthropic project, the Laramie Project to provide a security fence for a Laramie domestic Violence shelter.
