The 22-year-old woman’s body was found Sept. 19 in a remote area of Bridger-Teton National Forest in western Wyoming, and her death was ruled a homicide by strangulation.Authorities said they discovered unidentified human remains as well as items belonging to Brian Laundrie, who vanished after his fiancee, Gabby Petito, went missing during the couple’s cross-country trip and was later found dead.
