A 7-year-old girl found in Long Beach after being missing for more than a year was the first child to be recovered as a direct result of a Missing Children poster issued by Atty. Gen. John Van de Kamp's Missing Children program, officials announced. Coralee Tina Jones, who was abducted in August, 1986, by her mother after a two-week visit, was identified from her photograph that appeared on a July, 1987, poster, a spokesman in the attorney general's office said. Her legal custodian was her father, a resident of San Jose. Her mother has been arrested on felony child-stealing charges.
