William Fleming and Ben Herren
Agents of Justice
It was one of the most horrific events in the long struggle for African-American civil rights. Four young girls in the 16th Street Baptist Church were killed when a dynamite bomb planted outside exploded. It wasn't until 1977 that Robert Chambliss was found guilty and sentenced to life in prison, where he later died. Two other killers remained beyond the grasp of the law for nearly 40 years.
In 1996, the Birmingham FBI office reopened the case and assigned it to Special Agent William Fleming and Ben Herren, then a Birmingham police sergeant. Despite long odds that had thwarted investigations in 1965 and 1977, Fleming and Herren went to work.
As they meticulously dug through old files, Fleming uncovered crucial tape recordings of Thomas Blanton's conversations originally recorded during the initial investigation. He and Herren spent hundreds of hours reviewing the tapes; their contents proved to be essential evidence against Blanton and Bobby Frank Cherry. Both men were found guilty of murder and are now serving life sentences.
