Between 1979 and 1981, approximately 29 African-American children, teens, and young adults—mostly boys—were kidnapped and murdered. A majority of the killings shared common details. The FBI joined the multi-agency investigation in 1980. In our files, the major case is called ATKID, short for the Atlanta Child Murders. The investigation was closed following the conviction of Wayne Bertram Williams for two of the murders in 1982; after the trial, law enforcement linked Williams to 20 more of the 29 murders. This release was made prior to the creation of the FBI Vault; the files have since been renamed to enhance the clarity of the information, but the content remains the same.
