OVERLAND PARK, Kan. — The man accused of killing three people in attacks at Jewish-related sites in a Kansas City suburb on Sunday is a well-known white supremacist who has run for public office on a white power platform and who once was the subject of a nationwide manhunt.
Frazier Glenn Cross was booked into Johnson County jail in Olathe on a preliminary charge of first-degree murder after the attacks in Overland Park.
At a news conference, Overland Park police Chief John Douglass declined to publicly identify the man suspected of carrying out the attacks. But a jail official, speaking on the condition of anonymity because he wasn’t authorized to discuss the case, identified the suspect as 73-year-old Frazier Glenn Cross, of Aurora, Mo.
‘‘Today is a sad and very tragic day,’’ Douglass said at the news conference. ‘‘As you might imagine we are only three hours into this investigation. There’s a lot of innuendo and a lot of assertions going around. There is really very little hardcore information.’’
According to police, the attacks happened within minutes of one another. At around 1 p.m. a gunman opened fire on two people in the parking lot behind the Jewish Community Center of Greater Kansas City. He then drove a few blocks away to a Jewish retirement community, Village Shalom, and gunned down a woman or girl there, Douglass said. Officers arrested the suspect in an elementary school parking lot a short time later.
Authorities also declined to release the victims’ names pending notification of their relatives, but the family of the first two victims released a statement identifying them as Dr. William Lewis Corporon, who died at the scene, and his 14-year-old grandson, Reat Griffin Underwood, who died at Overland Park Regional Medical Center.
They were both Christian, and the family thanked members of their church congregation, among other people, for their support.
‘‘We take comfort knowing they are together in Heaven,’’ the family said. It asked for privacy to mourn.
Rebecca Sturtevant, a hospital spokeswoman, said family members said Corporon took his grandson to the community center so that the boy could try out for a singing competition for high school students. Reat was a freshman and an Eagle Scout.
Douglass said the suspect made several statements to police, ‘‘but it’s too early to tell you what he may or may not have said.’’ He also said it was too early in the investigation to determine whether there was an anti-Semitic motive for the attacks or if they will be investigated as hate crimes. The Jewish festival of Passover begins Monday.
‘‘We are investigating it as a hate crime. We’re investigating it as a criminal act. We haven’t ruled out anything. ... Again, we’re three hours into it,’’ he said.
Although the suspect was booked under the last name Cross, he is probably better known as Frazier Glenn Miller. A public records search shows he has used both names, but he refers to himself on his website as Glenn Miller and went by the name Frazier Glenn Miller in 2006 and 2010 campaigns for public office.
The Southern Poverty Law Center, which tracks hate groups, said it reached Miller’s wife, Marge, by phone and that she said authorities had been to their home and told her that her husband had been arrested in Sunday’s attacks. Calls by The Associated Press to a number listed as Miller’s on his website were met by a busy signal.
According to the law center, Miller has been involved in the white supremacist movement for most of his life. He founded the Carolina Knights of the Ku Klux Klan and was its ‘‘grand dragon’’ in the 1980s before the center sued him for operating an illegal paramilitary organization and using intimidation tactics against blacks. He later founded another white supremacist group, the White Patriot Party.
Miller, an Army veteran and retired truck driver, was the subject of a nationwide manhunt in 1987 after he violated the terms of his bond while appealing a North Carolina conviction for operating a paramilitary camp. The search ended after federal agents found Miller and three other men in an Ozark mobile home, which was filled with hand grenades, automatic weapons and thousands of rounds of ammunition. Miller tried running for U.S. House in 2006 and the U.S. Senate in 2010.
President Barack Obama released a statement expressing his grief over the attack, and Kansas Gov. Sam Brownback vowed to bring those responsible to justice.
‘‘My heart and prayers are with all those who were affected by today’s events,’’ Brownback said in a statement. ‘‘We will pursue justice aggressively for these victims and criminal charges against the perpetrator or perpetrators to the full extent of the law.’’
Michael Siegal, chair of the Jewish Federations of North America, also said in an emailed statement that ‘‘no community should have to face a moment such as this one.’’
‘‘Today, on the eve of Pesach, we are left to contemplate how we must continue our work building a world in which all people are free to live their lives without the threat of terror,’’ he said.
