With both Manahan and Anderson in failing health, in November 1983, Anderson was institutionalized, and an attorney, William Preston, was appointed as her guardian by the local circuit court. A few days later, Manahan "kidnapped" Anderson from the hospital, and for three days they drove around Virginia eating out of convenience stores. After a 13-state police alarm, they were found and Anderson was returned to a care facility. In January she was thought to have had a stroke, and on 12 February 1984, she died of pneumonia. She was cremated the same day, and her ashes were buried in the churchyard at Castle Seeon on 18 June 1984. Manahan died on 22 March 1990.
