If you or someone you know is the victim of domestic abuse, please call the National Domestic Violence Hotline at 800-799-7233. One year after the murder of 22-year-old travel blogger Gabby Petito, her grieving family is still fighting for justice in courts on opposite ends of the country. Her suspected killer, 23-year-old ex-fiance Brian Laundrie, refused to cooperate with police, then ran away and took his own life days after she was declared missing.
