Arthur Stanley Brown died in October 2021 at age 96, reportedly just as investigators were preparing to charge him. Working backward: if Brown was approximately 30 years old at the time of the 1966 disappearance (as the witnesses described the blond man), and he was born in 1924, what is the precise age discrepancy between the witness description and Brown's actual age in January 1966 — and what does this specific gap suggest about either the reliability of witness age estimation or the possibility that the identified man was not acting alone?
