COLUMBUS — The Ohio Statehouse is preparing to commemorate the repose of President Abraham Lincoln. An estimated 50,000 Ohioans viewed the assassinated Civil War president’s casket as it lay in the Statehouse Rotunda on April 29, 1865. After he was shot and killed, Lincoln’s funeral train stopped in Columbus on its 13-day, 1,600-mile journey. The Capitol is commemorating the anniversary on Friday.
