Sir-Kristopher Clayton Marshall was 3 years old when he was last seen on July 20, 1977, in Compton, California. He had been staying that night at the home of Earlene Williams with her children Ivy, Violet, and Yolanda. At about 4:30 a.m. the house caught fire; Earlene’s body was later found near the front door with signs of strangulation. None of the children were in the house when firefighters arrived.

Investigators reported a trail of blood leading from the home that ended at an alley, where it appeared someone might have entered a car. The following morning James Williams, Earlene’s estranged husband, was reportedly seen at a Denny’s in Grapevine with Sir-Kristopher and the three girls, but later that day friends picked him up and the children were not with him. Williams was arrested for Earlene’s murder and suspected of abducting the children. He was later charged in the children’s deaths; two trials ended in deadlocked juries and the charges were dismissed. Williams has since died.

Ivy Matory’s skeletal remains were found in Corona, California, in 2014; Sir-Kristopher and the other children remain missing and the case is unsolved. If anyone knew Sir-Kristopher or has information about where he might have been taken, please share what you know.
