Lisa Mae Zaharias was 15 months old when she was taken from Santa Ana, California, on November 20, 1987. She disappeared after her non-custodial mother, Susan Zaharias, left with Lisa and her older brother Christopher during a period of severe marital discord; the children’s father, Louis Zaharias, returned from work to find them gone. A felony warrant for child concealment and custodial interference was issued for Susan.

Reports place Susan and the children in sightings between 1987 and 1988 in states including Michigan, Pennsylvania, and California, and relatives are believed to possibly have helped Susan flee. Susan reportedly had a history of substance abuse that contributed to the family’s breakdown. Neither child nor Susan has been located; age-progressed images have been circulated and law enforcement and private investigators have continued to seek leads.

If anyone knew Lisa or Christopher as children, saw them with Susan in the late 1980s, or has information about Susan Zaharias’ whereabouts, please share what is known with investigators.
