Detroit, MI, August 17, 2026 —
A former inmate, William Whateley, has come forward with new details about Arch Sloan, a man who was questioned in connection with the unsolved Oakland County Child Killer (OCCK) case. Whateley claims he shared a prison cell with Sloan, who passed away in June.
Sloan had a criminal record as a convicted pedophile with prior sex offenses against minors. He was investigated in relation to the 1976 murder of Mark Stebbins, one of the victims attributed to the OCCK. Forensic evidence, specifically hairs found in Sloan’s vehicle, was previously linked to Mark Stebbins and another victim in the case.
Whateley has shared his recollections of interactions and observations from their time incarcerated together. He recounted conversations and insights gained during their shared confinement, which he suggests point to Sloan’s potential involvement in the OCCK crimes. However, Whateley’s statements do not provide definitive proof of Sloan’s guilt.
The Oakland County Child Killer case remains one of Michigan’s most enduring and disturbing unsolved mysteries, involving the murders of four children between 1976 and 1977. The investigation has spanned decades, with numerous leads pursued and suspects identified, but no one has ever been convicted in connection with the crimes.
Arch Sloan’s death means he can no longer be formally charged in connection with the case. Whateley’s testimony adds another layer to the ongoing public interest and investigative history surrounding the OCCK and its potential suspects.
