BIRMINGHAM, Alabama: Armed with new information, the FBI is reopening its investigation into one of the most shocking racist incidents of the civil rights movement, the 1963 bombing of the Sixteenth Street Baptist Church, which killed four children. "It's a crime that has gone unsolved except one local conviction and it remains a sore part of American history that we would like to heal," said Joseph Lewis, FBI special agent in charge in Birmingham. "We feel we have an opportunity to do so this time and we want to take one last shot at it." Since the 1963 attack, only one person, Ku Klux Klansman Robert Edward Chambliss, has been convicted. The FBI believes at least three other men were involved in the blast, which took the lives of an 11-year-old girl and three 14-year-old girls.
