In Oakland County, one of the most notorious alleged crime sprees is one that remains unsolved. Between 1976 and 1977, four children, two boys and two girls, were found murdered on Woodward Avenue between Ferndale and Birmingham. The media referred to the murderer as the Oakland County Child Killer. A recent breakthrough has brought the case back in the spotlight. FBI investigators have linked evidence, specifically hairs found the backseat of Arch Edward Sloan's vehicle with hairs found on two of the four victims. A Mitochondrial DNA test was used to match hairs. This is the first breakthrough that links at least two of the children's murders to each other.
