In 1963 , Gary Thomas Rowe may have helped perpetrate the 16th Street Baptist Church bombing that killed four young girls . One of the Klansman eventually convicted of the crime , Robert E. Chambliss , said that it was Rowe who bombed the church . Rowe , who was no stranger to dynamite , had twice failed polygraph tests when questioned as to his possible involvement in the 16th Street Baptist Church bombing , investigative records show . Because of this , the FBI and the prosecution did not use Rowe as a witness in Chambliss 's trial
