Authorities have identified the man who allegedly killed three people and wounded two more at two Jewish centers in Kansas yesterday as a former Ku Klux Klan leader. 

The Southern Povery Law Center says Frazier Glenn Miller—also known as Frazier Glenn Cross—is a founding member of the Carolina Knights, overseeing their activities during the 1980s until he was arrested and convicted of running a paramilitary organization. 

Miller, 73, has been accused of shooting Dr. William Lewis Corporon and his grandson, 14-year-old Reat Griffin Underwood, in the parking lot right behind the Jewish Community Center of Greater Kansas City in Overland Park, Kan. yesterday afternoon. Overland Park police say he then drove to the Village Shalom Retirement Community parking lotarmed with a handgun, a shotgun and possibly an assault rifleand fatally shot a young woman. 

The incident took place a day prior to the beginning of Passover.

Miller was arrested shortly after at an elementary school. During his arrest, he reportedly shouted "Hail Hittler." The third victim's name has yet to be released, and Miller faces first-degree murder charges.
