Teton County Coroner Dr. Brent Blue said at the time that there are still many details he cannot share about the 22-year-old's death due to local rules but stated that her body appeared to have been left in the wilderness for three to four weeks before it was discovered and examined.
Petito's initial disappearance went viral as people tried to solve the case of the missing influencer. The search for her fiancé began after he was said to have gone for a hike shortly after Petito was reported missing and never returned.
Laundrie's parents initially told investigators that he left home on Sept. 14 to hike Carlton Reserve, which led to an extensive search of the 25,000-acre area. Bertolino later said, "We now believe the day Brian left to hike in the preserve was Monday, Sept. 13."
