Updated on Oct. 24, 2026 in Accidents

Tulsa County detectives are working with family members and a witness to investigate the disappearance of 22-year-old Lisa Addington, who was last seen on May 16, 1984. The investigation examines potential links to items discovered along the Arkansas River in 1998.
Why it matters
The case remains active as investigators attempt to determine if evidence found near the Arkansas River correlates with Addington's disappearance. High water levels have previously hindered efforts to search the specific area where the items were discovered.
Lisa Addington was 22 at the time of her 1984 disappearance and would be 64 years old in 2026. The investigation into the items discovered in 1998 is currently limited by environmental conditions at the site.
