Sarah Avon, 6, has been missing from Joliet, Illinois since July 21, 1981. She was last seen near Oscar Avenue walking across the street near her home on 716 Richards Street around 8:20 p.m.
Her mother stated in an newspaper interview shortly after she went missing, “”Sarah and her sister, Marie, 5, had been playing track ball moments earlier … Marie went to the front porch of the home next door to play a game. That’s when Sarah walked across the street.”
This week the authorities named William “Billy” Redden as a suspect, reports ABC Chicago. Billy lived two blocks away from Sarah in the 200 block of Reichman Street. He also was Sarah’s father’s cousin. Billy was convicted of aggravated battery against a 19-month-old child 10 years before Sarah went missing. He was released in 1975. Billy died in 2010.
The Will County Sherriff Jungle stated, they have gone over the case again. “After completing the review, numerous individuals were re-interviewed, scene re-assessments where conducted, an evidence audit was conducted, and modern forensic methods and technologies were reviewed for their applicability to this case.”
The authorities in May 2019, returned to Redden’s former residence and searched. In October 2019, they searched 2-acres of property once owned by Redden. Nothing was found.
