Andrea Jean Coyle, known as Andi, was 30 when she was last seen on December 19, 1978. She left her grandparents’ home in Bellwood, Pennsylvania, to go to the Woodrow Wilson Adult Learning School in Altoona to turn in textbooks and get her grades. After arriving she left the school sometime before noon without collecting her grades and didn’t return. She had all her cash but left her identification behind and was never seen or heard from again.

Andrea had a history of serious mental-health struggles, including a nervous breakdown in 1971, electroconvulsive therapy, a brief marriage that ended after a 1973 suicide attempt, transient periods of hitchhiking around the eastern United States, a short U.S. Army enlistment from September 1974 to February 1975 with a medical discharge, and a 1976 arrest in Washington D.C. that resulted in a court-ordered hospital stay. At the time of her disappearance she was voluntarily receiving treatment at the psychiatric ward of Altoona Hospital.

No evidence has surfaced to confirm whether she is alive or deceased, and her family remains without closure. Did anyone in Bellwood or Altoona see Andrea on December 19, 1978, or remember her travels after that date?
