Christina was last seen on June 1, 1999, traveling with her aunt to Rialto, California. Christina was at the time believed to have arrived at her destination a week later; she has not been heard from since. A federal indictment in 2008 accuses the aunt of killing Christina, and alleges the woman's husband buried the girl's body in woods outside Ozark. According to the indictment, Christina was living with her aunt and uncle in Ozark when she got into an argument with her aunt. The indictment alleges the aunt took the girl into a bathroom and killed her, possibly by drowning her in the bathtub. The indictment says the uncle dug a hole in woods outside Ozark and put his niece's body in it, then returned home and burned her clothes. The federal indictment charges the couple with making false statements to FBI agents investigating the disappearance of Christina Richart. The teenager's body has not been found. The couple entered not guilty pleas in the federal case.
