Anthony Terrell believes an imprisoned man currently serving two life sentences may not have been the person who murdered his brother as part of a killing spree that rocked Atlanta four decades ago. Terrell hopes new light can be shed nationwide on the murders that terrorized the African American community in the city within a two-year time span with the HBO documentary Atlanta’s Missing and Murdered: The Lost Children. The five-part series, which begins Sunday, will explore how the victims’ family members and others remain skeptical about Wayne Williams being the sole killer, despite evidence linking him to those murders and 10 others.
