Frazier Glenn Miller, 73, of Aurora, Mo., was arrested today for the murder of three people at two separate Jewish Community Centers in Overland Park, Kan. Miller, who was arrested using the alias Frazier Glenn Cross, has been in the movement nearly his entire life. Miller is the former “grand dragon” of the Carolina Knights of the Ku Klux Klan, which he founded and ran in the 1980s before being sued by the Southern Poverty Law Center (SPLC) for operating an illegal paramilitary organization and using intimidation tactics against African Americans.
