Susan Carol Cassell, 35, vanished from her Glendale, Arizona, home on January 3, 1991. A nurse and U.S. Army veteran, she worked at Boswell Memorial Hospital in Sun City and had just finished a long shift the day she disappeared. Her husband, James F. Cassell, was the last person to see her; his account says she returned home unexpectedly and then left again. Susan’s car stayed at the house and several uncashed hospital paychecks were left behind.

Shortly after she was last seen, her husband and their four-year-old son took an overnight camping trip and reported Susan missing when they returned on January 4. Her mother said it was highly uncharacteristic for Susan to vanish and that, while her marriage had some problems, Susan was generally in good spirits. The family does not believe she would have voluntarily left her young son. Over a year later, in February 1992, James Cassell was granted a divorce and later moved to Pennsylvania with their son. Law enforcement has said they suspected foul play, but no arrests have been made.

Susan is described as social, religious, and she has a birthmark on the back of her neck; she wears glasses or contact lenses. Does anyone who knew Susan, the family, or her routines in Glendale or at Boswell Memorial have information that could help explain what happened?
