Prosecutors introduce pattern evidence mid-trial that they assert links him to ten of the child murders. Drawing predominantly on hair and carpet fibers found on the victims, the jury delivers a swift guilty verdict in February 1982. Just days later, the Atlanta police department shuts down the task force investigating the 30 murders, and attributes most of the cases to Wayne Williams. A year later, as the dissent of an unconvinced community grows louder, the Georgia Supreme Court makes the controversial decision to deny Williams’ plea for a retrial.

In the mid-1980s, Wayne Williams’ appeals attorney Lynn Whatley anonymously receives shocking new evidence connecting members of the Klan to the murders. An undercover informant and several investigators take the stand as a judge evaluates Williams’ plea for a retrial. Forty years after the murders began, the victims’ family members gather to grieve, discuss Williams’ guilt or innocence, and assert their unwavering commitment to finding out what really happened to their children. Series finale.
