Christina Marchell Richart was 14, with blonde hair and green eyes, when she was last seen in Ozark, Arkansas, in the summer of 1999. After their father died in 1996, Christina and her two younger brothers had been placed with their paternal uncle and his wife, Charles and Wanda Richart, in 1997. Concerns about the children’s welfare led to the removal of both brothers from the Richarts’ care by 2000.

The brothers’ adoptive mother formally reported Christina missing in 2005 after receiving conflicting accounts of her whereabouts. The Richarts had long said Christina had left voluntarily with a great-aunt and that they received phone calls from her until April 2000; they also cashed Social Security checks issued for Christina for eighteen months after she vanished. In 2008 a former housemate, Joann Holdman, said she had witnessed an argument in which Wanda forced Christina into a bathroom. Charles later pleaded guilty to conspiring to make a false statement to the FBI and said he buried Christina in the Ozark National Forest the day after her death; Wanda pleaded no contest to second-degree murder and was sentenced to prison. Christina’s remains have not been recovered.

Does anyone have information about Christina’s last known movements or the Ozark National Forest area where she was said to have been buried?
