A man suspected of fatally shooting three people at two Jewish-affiliated facilities could be formally charged with hate crimes as early as Tuesday.
Police say Frazier Glenn Cross is the suspect in Sunday's shooting death of a boy and his grandfather outside a Jewish community center near Kansas City, Kansas, and then a woman at a nearby Jewish assisted living facility.
The hate crime charges are expected even though the victims were Christian, legal experts say.
For now, Cross faces charges of premeditated first-degree murder, officials said.
Investigators have "unquestionably determined" that his actions were a hate crime, Overland Park Police Chief John Douglass said.
If the suspected shooter is charged and convicted of a hate crime, under federal law, the death penalty could be on the table. That would apply if the charge is that the defendant was motivated by the victims' "race, color, religion or national origin."
Cross is the founder and former leader of the Carolina Knights of the Ku Klux Klan and the White Patriot Party, according to the Southern Poverty Law Center, which monitors hate groups. Both organizations operated as paramilitary groups in the 1980s, according to the SPLC.
In the 73-year-old's anti-Semitic and white-supremacist activities, he has also used the name Frazier Glenn Miller, the SPLC said.
After he was apprehended at a nearby elementary school, Cross sat in the back of a patrol car and shouted "Heil Hitler!" video from CNN affiliate KMBC shows.
He obtained firearms from a "straw buyer," a middleman with a clean record who could buy weapons legally and then sell or give them to Cross, allowing Cross to avoid federal background checks, a U.S. law enforcement official said. He had three guns when he was arrested Sunday, authorities said.
The shootings took place at the Jewish Community Center of Greater Kansas City and the Village Shalom Retirement Community in Overland Park a day before the start of Passover, a major Jewish holiday.
The police chief said the gunman shot at five people, none of whom he is believed to have known. There were no other injuries, authorities said.
Police were investigating statements Cross made after his arrest but declined to provide additional details, Douglass said.
The Anti-Defamation League said it warned last week of the increased possibility of violent attacks against community centers in 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."
On Monday, the ADL reissued a security bulletin to synagogues and Jewish communal institutions across the country, urging them to review their security plans for the Passover holiday, which began at sundown Monday.
'That idiot ... knocked a family to its knees'
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 performance of "To Kill a Mockingbird" was about to begin, and auditions were under way 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 there to audition for the singing competition. His grandfather, William Lewis Corporon, was driving him. The bullets struck them in their car. Both died.
"That idiot absolutely knocked a family to its knees for no reason," Reat's uncle and William's son, Will Corporon, said at a news conference Monday afternoon.
Grandfather and grandson were Methodists, their pastor, the Rev. Adam Hamilton, told CNN on Monday.
A woman caring for her mother
The gunman then drove to the retirement home, where he shot the third victim in the parking lot. Authorities identified her as Terri LaManno, who was visiting her mother as she usually did every Sunday at Village Shalom.
LaManno's Catholic church, St. Peter's Parish, posted a message on its website calling LaManno "a loving mother and wife, and a gentle and giving woman."
The Children's Center for the Visually Impaired in Kansas City, where LaManno worked as an occupational therapist, described her as a "gracious, generous, skilled and deeply caring individual who made a great difference in the lives of so many children and their families."
'A raging anti-Semite'
Cross is a "raging anti-Semite" who has posted extensively in online forums that advocate exterminating Jews, the Southern Poverty Law Center said.
He has called Jews "swarthy, hairy, bow-legged, beady-eyed, parasitic midgets."
According to the SPLC, Cross 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, Cross 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."
