Madelynn Nicole Keith, known as Maddie, was 18 when she disappeared from her Toledo, Ohio, home in early summer 2018. She left on June 3 with a backpack containing extra clothing, which suggested she expected to be away for a short time. Madelynn had a traumatic brain injury that affected the right side of her body and left her with the cognitive functioning of a middle schooler; she also had a slight limp and scars on her right forearm and ankle. Those medical vulnerabilities are why she is considered endangered missing.

Initial leads pointed to possible travel outside Ohio. Social media check-ins placed her in locations in California and Texas, and her family received a hospital bill showing medical treatment in El Centro, California, on August 23, 2018. There was an unconfirmed sighting reported in San Bernardino around the same time. Those tips are the last known information about her movements after leaving Ohio. If anyone has information about Madelynn’s whereabouts or saw her in 2018 in California, Texas, or en route, please come forward.
