and retirement community in Overland Park, Kansas, that left three people dead is reportedly the former Grand Dragon of the Carolina Knights of the Ku Klux Klan.

Fraiser Glenn Cross Jr., of Aurora, Mo., was taken into custody in the parking lot of an elementary school near the scene of the shootings, and was booked on a charge of first degree murder, according to the Johnson County, Kansas, Sheriff's Office.

Cross is an alias for Frasier Glenn Miller, the former KKK leader, according to the Southern Poverty Law Center.

In a statement released tonight, the SPLC said it was able to identify Cross as Miller after a phone conversation with Miller's wife, Marge, in which she told them police had come to her home and told her that her husband had been arrested in the shootings.

The address listed by the sheriff's office for Cross is the same address Frazier Glenn Miller used when filing candidate papers to run for Congress in Missouri in 2006 and when he sued the secretary of state for refusing to let him on the ballot.

Among the three people killed in the shootinngs were a 14-year-old Eagle Scout and his grandfather, according to the family of the two.

"It is with deep sadness that we confirm the tragic loss of Dr. William Lewis Corporon and Reat Griffin Underwood (Losen) who died as a result of the injuries they sustained in today's shooting at the Jewish Community Center. Dr. Corporon was Reat's Grandfather, whom he loved very much," said a statement signed "Will Corporon, Son and Uncle."

The two were shot at the town's Jewish Community Center, Overland Park Police Chief John Douglass said. One died at the scene and the other died after being taken to a hospital, he said.

The third victim was a woman who was shot at Village Shalom retirement community, Douglass said. She died on the scene.

It was believed the shooter fired at two other people, but neither was hit, the police chief said.

"We have no indication that he knew the victims," Douglass said.
