Nancy Jason, 18, of Bethesda, Maryland, was reported missing on July 17, 1977. She was described by family and friends as bright and ambitious and was last seen in her neighborhood; her disappearance was described as sudden and out of character given a stable routine and close ties to those around her.

Local authorities conducted searches in areas where she was last seen and asked the community to help. Family members distributed flyers, worked with local media, and joined public appeals while detectives interviewed relatives, friends, and acquaintances to reconstruct Nancy’s last known movements. Over time the investigation produced no credible leads and the case stalled, leaving her family distressed and uncertain.

The family has continued to keep her story in the public eye through events and appeals. If anyone knew Nancy, saw her in Bethesda in July 1977, or has information that could help, please come forward.
