April 15, 2014— -- A leading white nationalist says the accused gunman in the Jewish center shootings in Kansas was a raging alcoholic who long ago lost ties with his own pro-white community.
"I think Glenn had gone insane, completely insane in recent years,” Don Black, a former Ku Klux Klan member and the founder of Stormfront, the “White Pride World Wide” website, told ABCNews.com. "Probably because of the alcohol. But whatever it was, he did us a lot of damage this weekend.
"He killed Christians. The whole thing was completely insane. His brain has rotted,” Black added.
Frazier Glenn Miller, a former KKK leader, allegedly killed three people Sunday when he opened fire at two Jewish community centers in Kansas. The charging documents used the last name of Miller, but he was addressed as "Mr. Cross" by the judge at a hearing today. He set his bond at $10 million. Cross is an alias used by the suspect.
Miller was charged earlier today with one count of capital murder and a second count of premeditated first degree murder. The capital murder charge makes him eligible for the death penalty.
Miller's lawyer did not return a call for comment.
Despite his reported allegiance to another anti-Semitic website, Vanguard News Network, Miller had been shunned by the white nationalism community for years, Black said.
He and Miller had a falling-out after Miller testified against fellow KKK members as part of a plea bargain in 1988, Black said.
"It doesn’t matter what side you’re on, people don’t like rats,” Black said. "He’d been a government informant testifying against personal friends of mine. He came back years later and expected to be accepted back in our circles.”
But there were other reasons Black — who said he never allowed Miller to post on his website’s forum — said the accused killer wasn’t welcome.
“He had a history of too much alcohol, being a blowhard generally,” Black said.
Black, 60, said he was shocked to learn Miller is the suspect in the shootings.
“I would not have anticipated his doing that,” he said. "I thought he was most mostly talk.”
Commenters on Vanguard News Network, where Miller reportedly posted under the username “Rounder,” were equally surprised.
"This is really out of character, the randomness of it,” a user named “313Chris” wrote. “Just doesn’t read like something he would do.”
Others rallied to support Miller, whose is accused of killing a 14-year-old boy and two adults in the shooting.
“Glenn Miller has more guts and courage in his little finger than these keyboard warriors have in their entire body,” a user named “SA Mann” wrote.
Sinister comments proved some of Miller’s peers approved of the bloodshed.
“He needed to go on a more crowded day,” senior member “Dan Hadaway” wrote. “It didn’t sound like it was too well thought out.”
The Southern Poverty Law Center, a watchdog for hate crimes, calls Black’s Stormfront “the first major hate site on the Internet.”
The group has urged authorities to read forums on sites like Stormfront and Vanguard News Network.
“It’s not like we don’t know where this type of hatred and violence is bred,” said Heidi Beirich of the Southern Poverty Law Center in an interview with ABC News. “These forums have to be watched very carefully within whatever the legal bounds are. This is where these people live. This is where our domestic terrorism is coming from.”
