Greg McDowell reportedly saw his killer approach before he was gunned down as he led Bible study at Creflo Dollar's World Changers church in College Park on Wednesday. McDowell, 39, was pronounced dead at South Fulton hospital following the 10:30 a.m. shooting. The suspected shooter, Floyd Palmer, 59, was taken into custody hours later outside Macy's at Lenox Square Mall in Buckhead, north of Atlanta.
