Michelle Leone Duncan, known as Shelly, was 18 when she was last seen in Los Angeles on November 4, 1984. In the hours before she vanished she called her mother twice, saying she was afraid of a man she knew and asking to be picked up. After those calls she was never heard from again.

Michelle had moved from Stockton to Southern California with her partner Steven Angle; they lived together and had a son. The exact location of her calls and other key details remain unclear, and the case received little media coverage at the time. Her disappearance is classified as suspicious and her family has continued to seek answers.

Does anyone with memories of Los Angeles in November 1984, or who knew Michelle, Steven Angle, or their circle, have information that could help clarify what happened?
