Pettito's mother slam narcissists' confession #BrianLaundrie #GabbyPetito #stephenBertolino Gabby Petito's mom has slammed Brian Laundrie's notebook confession where he claimed her death was a mercy killing after she slipped in a stream and hit her head. Laundrie, 23, admitted murdering his 22-year-old fiancée at Grand Teton National Park in Wyoming on their country-wide road trip in August 2021. Petito's mom Nichole Schmidt said she was 'fed up' after Laundrie's notebook confession was revealed. She shared an image on Twitter that said 'narcissists rewrite history', along with hashtags including 'the truth will be revealed', 'selfish' and 'justice for Gabby'. Laundrie claimed in the notebook she fell into a creek and injured herself but as she was severely hurt, crying in pain and shivering from the cold, he decided to kill her. Petito's death was ruled a homicide by manual strangulation.
