On Sunday, family and church attendees remembered the four girls killed on Sept. 15, 1963, when a bomb exploded in the 16th Street Baptist Church in Birmingham 61 years ago. The church held a commemoration service as those in attendance recalled the loss of 14-year-olds Addie Mae Collins, Carole Robertson, Cynthia Wesley and 11-year-old Denise McNair, who were killed that morning.
