Oakwood University Choir Honors Slain Officer with Song and Walk. The Aeolians, an Oakwood University choir, sang and walked a mile in honor of a Columbus, Ohio, police officer who was killed during a SWAT standoff. Members of the Central Seventh-day Adventist Church brought the choir that was visiting Columbus for a performance. The church and the choir decided to pay tribute by singing the national anthem, offering comfort to the officers who remain. The pastor of Columbus Central, John Boston, is also a Chaplain for the Columbus Police Department.
