Later Prosecutions
FBI investigations gathered evidence pointing to four suspects: Robert Chambliss, Thomas E. Blanton Jr, Herman Cash, and Bobby Frank Cherry. According to a later report from the Bureau, “By 1965, we had serious suspects—namely, Robert E. Chambliss, Bobby Frank Cherry, Herman Frank Cash, and Thomas E. Blanton, Jr., all KKK members—but witnesses were reluctant to talk and physical evidence was lacking. Also, at that time, information from our surveillances was not admissible in court. As a result, no federal charges were filed in the ’60s.” Although Chambliss was convicted on an explosives charge, no convictions were obtained in the 1960s for the killings.
Alabama Attorney General William Baxley reopened the investigation after he took office in 1971, requesting evidence from the FBI and building trust with key witnesses who had been reluctant to testify in the first trial. The prosecutor had been a student at the University of Alabama when he heard about the bombing in 1963. “I wanted to do something, but I didn’t know what.”
In 1977 former Ku Klux Klansman Robert "Dynamite Bob" Chambliss was indicted in the murder of all four girls, tried and convicted of the first-degree murder of Denise McNair, and sentenced to life in prison. He died eight years later in prison.
Thomas E. Blanton, Jr. was tried in 2001 and found guilty at age 62 of four counts of murder and sentenced to life in prison.
Herman Cash died in 1994 without having been charged. Bobby Frank Cherry, also a former Klansman, was indicted along with Blanton. Judge James Garrett of Jefferson County Circuit Court ruled "that Mr. Cherry's trial would be delayed indefinitely because a court-ordered psychiatric evaluation concluded that he was mentally incompetent.” He was later convicted in 2002, sentenced to life in prison, and died in 2004.
