A Missouri man, with a long virulent history of anti-Semitism, is suspected of killing a boy and his grandfather outside a Jewish community center in Kansas City and a woman at a Jewish assisted living facility nearby.
While police in Overland Park, Kansas, stopped short of labeling the Sunday attacks a hate crime until they were further along in their investigation, the suspect — Frazier Glenn Miller — is the founder and former leader of the Carolina Knights of the Ku Klux Klan and the White Patriot Party.
Both operated as paramilitary organizations in the 1980s, according to the Southern Poverty Law Center, which monitors hate groups.
The 73-year-old Miller, who also goes by Frazier Glenn Cross, faces charges of premeditated first-degree murder. He is expected to appear in court Monday.
The shootings took place at the Jewish Community Center of Greater Kansas City in Overland Park and at the Village Shalom Retirement Community in Leawood — a day before the start of Passover, the major Jewish spring festival.
“The timing is terrible. The timing is awful,” said Rabbi Herbert Mandl, a chaplain for the Overland Park police.
In all, the gunman shot at five people, none of whom he’s believed to have known, said Overland Park Police Chief John Douglass.
Three people died; the other two were not injured.
Shortly afterward, authorities arrested the suspect at a nearby elementary school.
Video from CNN affiliate KMBC showed the suspect sitting in the back of a patrol car and shouting, “Heil Hitler.”
Douglass said police were investigating statements the man made after his arrest, but declined to provide additional details.
The Anti-Defamation League said it warned last week of the increased possibility of violent attacks against community centers during the coming weeks, “which coincide both with the Passover holiday and Hitler’s birthday on April 20, a day around which in the United States has historically been marked by extremist acts of violence and terrorism.”
‘This has left us all breathless’
The shooting began just after 1 p.m. Sunday in the Jewish community center’s parking lot.
Inside the center was a hive of activity. A rehearsal for a production of “To Kill a Mockingbird” was underway as were auditions for “KC Superstar,” an “American Idol”-style contest for the best high school singer in the Kansas City area.
Outside, the gunman opened fire. Police said he was armed with a shotgun and may have been carrying other weapons.
Reat Griffin Underwood, 14, was coming to audition for the singing competition. His grandfather, William Lewis Corporon, was driving him. The bullets struck them in their car. Both died.
Corporon was a doctor who practiced family medicine in Oklahoma for many years before moving to Kansas City to be closer to his grandchildren.
“He cherished his family,” the family said in a statement.
Reat was a high school freshman who was active in debate, theater and had “a beautiful voice,” his family.
At a vigil Sunday night at the United Methodist Church of the Resurrection, Reat’s mom walked up to the podium and introduced herself as the mother and daughter of the community center victims. The gathered gasped.
“I know that they’re in heaven together,” the mother, Mindy Corporon, said.
Jacob Schreiber, president of the community center, remembered the family fondly.
“This is one of the nicest, kindest, most supportive families that we have here,” he said. “This has left us all breathless.”
The center immediately went into lockdown.
“Some of these kids were taken into locker rooms and told to lay on the floor as the shots rang out,” CNN affiliate KSHB reporter Lisa Benson told CNN.
Jeff Nessel, a parent, told the Kansas City Star he had just dropped his 10-year-old son off at the community center when a staff member told him to get back inside because there had been a shooting.
“We’ll keep you on lockdown. You’re safe here,” Nessel said a staff member told him.
‘Stay away from the windows’
The gunman then drove to the retirement home, where he shot the third victim in the parking lot. She has not been identified.
Amy Rasmussen was helping with her grandmother’s laundry when residents were warned by a staff member.
People “were told by one of the staff that it was a tornado warning … and stay away from the windows,” Rasmussen told the newspaper.
‘A raging anti-Semite’
Miller, the suspected shooter, is a “raging anti-Semite,” who has posted extensively in online forums that advocates exterminating Jews, the Southern Poverty Law Center (the SPLC) said.
He has called Jews “swarthy, hairy, bow-legged, beady-eyed, parasitic midgets.”
According to the SPLC, Miller founded and ran the Carolina Knights of the Ku Klux Klan in the 1980s. He was forced to shut down after the SPLC sued him for operating an illegal paramilitary organization and intimidating African-Americans.
He then formed another group, the White Patriot Party.
In the late 1980s, Miller spent three years in prison on weapons charges and for plotting the assassination of SPLC founder Morris Dees. The short sentence was a result of a plea bargain he struck with federal prosecutors. In exchange, he testified against 14 white supremacists in a sedition trial in Arkansas in 1988.
“He was reviled in white supremacist circles as a ‘race traitor and, for a while, kept a low profile,” according to an SPLC profile of him. “Now he’s making a comeback with The Aryan Alternative, a racist tabloid he’s been printing since 2005.”
