In September 2017, Orion Krause left his home in Rockport, Maine without communicating his travel plans to his family. When he called his mother the next day informing her he was in Boston, she was happy to give him a ride home and relieved to learn he was safe. Before making the trek to Maine, Orion's mother suggested they visit his grandparents. This short stop would go on to shock the town of Groton for years to come.
