Question: Which serial killer, born in 1958, was responsible for at least 23 murders from 1979-1981 in Atlanta, dubbed the Atlanta Child Murders?
Context: Gary Leon Ridgway (born February 18, 1949) is an American serial killer known as the Green River Killer.  He was initially convicted of 48 separate murders and is presumed to be responsible for more than 90.  As part of his plea bargain, an additional conviction was added, bringing the total number of convictions to 49, making him the most prolific American serial killer in history according to confirmed murders.  He murdered numerous women and girls in Washington State during the 1980s and 1990s. The Texarkana Moonlight Murders, a term coined by the news media, references the unsolved murders committed in and around Texarkana in the spring of 1946 by an unidentified serial killer known as the "Phantom Killer", or "Phantom Slayer".  The killer is credited with attacking eight people within ten weeks, five of whom were killed.  The attacks happened on weekends between February 22, 1946 and May 3, 1946.  The first two victims, Jimmy Hollis and Mary Larey, survived.  Some police officers are not sure if their attack was connected with the murders.  The first double murder, which involved Richard Griffin and Polly Ann Moore, happened four weeks later.  The second double-homicide, involving Paul Martin and Betty Jo Booker, occurred exactly three weeks from the first murders.  The Texas Rangers came in to investigate, including the famous M. T. "Lone Wolf" Gonzaullas.  Finally, almost exactly three weeks later, Virgil Starks was killed and his wife, Katie, was severely wounded.  Most officials no longer connect that attack to the other murders.  Contrary to popular belief, the killer did not attack during a full moon, but did strike late at night. My Brother the Serial Killer is a 2012 American television documentary about serial killer Glen Rogers, otherwise known as the "Casanova Killer", who was convicted for a series of murders and arsons.

"My Brother the Serial Killer" received widespread media attention for Clay's claims that his brother was responsible for the 1994 murders of Nicole Brown Simpson and Ronald Lyle Goldman.

The Atlanta Child Murders is a TV miniseries that aired on February 10 and 12, 1985 on CBS.  Inspired by true events, the miniseries examines the so-called "Atlanta child murders" of the late 1970s and early 1980s. The Atlanta murders of 1979–1981, sometimes called the Atlanta Child Murders (although several of the purported victims were adults), were a series of murders committed in the American city of Atlanta, Georgia, from the middle of 1979 until May 1981.  Over the two-year period, at least 28 African-American children, adolescents and adults were killed.  Wayne Williams, an Atlanta native who was 23 years old at the time of the last murder, was arrested for and convicted of two of the adult murders, and sentenced to two consecutive life terms.  Police subsequently have attributed a number of the child murders to Williams and closed the cases, although he has not been tried or convicted in any of those cases.
