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.

Roberta and Chris Laundrie issued a damning statement against the Netflix true-crime documentary last week (19 Feb)
