Christie and her brother had been living in the foster home for only three days prior to her disappearance. Her school allegedly called her foster parents at 1:30pm on December 14, 1978, and told them Christie never arrived in class. Christie's case was reopened in recent years by authorities. Two individuals confessed to her supposed murder some years before, but investigators now believe they were not connected to her case. Authorities speculated that Christie may have been abducted by an unidentified family member and either murdered or hidden in a safe location; some of her relatives have suggested her foster family was involved. However, there are no suspects in her disappearance.
