Petito’s parents, Joseph Petito and Nichole Schmidt, are currently suing the Laundries after claiming they knew that their son had intentionally killed their daughter and refused to tell them.

Brian Laundrie’s sister is speaking out for the first time since the release of Netflix’s documentary "American Murder: Gabby Petito." The documentary covers Brian’s 2021 killing of Petito, followed by his suicide.

The documentary follows the case of Gabby Petito, who disappeared while on a road trip with her fiancé Brian Laundrie before being found dead.
