Circumstances of Disappearance
Smith disappeared with his mother, Edyth Ann Warner from their Las Cruces, New Mexico residence on February 23, 1991. They've been gone since February 23, when they walked out of their home in student housing at the New Mexico State University in Las Cruces.
Warner's husband Henry Warner filed a missing persons report seven days later. He told police the couple had been having marital problems and that his wife told him she and Nicholas, her son from a previous marriage, were going to stay with a friend. They left their home by foot the day they disappeared. Warner left behind her car and 3-year-old son, Andrew. She took almost $1,000 in cash and $10,000 in gold coins.
According to family and friends this is very uncharacteristical of her. Neither has been seen or heard from again. There are concerns for their safety.
