When does The Disappearance of Gabby Petito return?

Gabrielle Venora Petito was killed by her fiancé Brian Laundrie at the age of 22 while they were traveling together on a van life journey across the United States. The case gained widespread attention due to the couple's documenting of their travels on social media, leaked police body camera video footage, 9-1-1 emergency dispatch call recordings, eyewitness accounts, and the extensive media coverage. The FBI later announced that he had admitted to killing Petito in his notebook found near his remains.
