Frazier Glenn Miller, the ex-klansman and lifelong bigot who faces trial for killing three people at two Kansas Jewish centers earlier this month, ran up quite a rap sheet—including the time cops caught him in a car having sex with a black male prostitute dressed as a woman.

That revelation was part of a long, deep investigation into Miller's chilling background as a self-styled soldier for the white nationalist cause.

In the late '80s, Miller—who founded the Carolina Dragons of the Ku Klux Klan and the White Patriot Party—struck a plea deal with federal prosecutors to roll over on his white brothers in the cause and avoid a long prison stretch. After leaving prison, the feds changed his name to Frazier Glenn Cross and tried to start his life anew, albeit with just as much racism and more violence.

But now we can understand why Miller was so quick to accede to a quickie name makeover. According to ABC News, his life in the '80s included some hypocritical sexual proclivities:

In the course of their investigation, authorities also learned the stunning details of Miller's arrest a year earlier. Raleigh police officers had caught Miller in the back seat of a vehicle, in mid-act with a black male prostitute masquerading as a woman. "It was pretty shocking," says McCullough, "because of his personal stances that he had taken and what he was now accused on engaging in." McCullough says he has read the police report of the incident but declined to comment on the specifics. "I would rather not go into the details," he said. "They're rather salacious. I think the facts speak for themselves and people can draw their own conclusions about how incongruous that is." Miller was not charged in connection with the prostitution arrest and no public record of the incident could be located. But in a recorded phone call with the Southern Poverty Law Center last fall, Miller claimed that he had lured the prostitute to the meeting with the intention of beating him.

It's hard to know how to process this. Especially breathtaking is Miller's assumption that the criminal (and, to his mind, moral) offense of fucking a black male hooker was mitigated by the fact that, hey, he was totally planning to beat up that hooker.

As we all now know, Miller was capable of much, much worse. Yet his old prosecutors point out that even if he'd never cooperated with them, he still would have been a free man by now, and he still probably would have been able to pull off his anti-semitic massacre in Kansas.

"The guy was a stone-to-the-bone Nazi," one anti-racist researcher told ABC. "He never gave that up. I am on the record as saying the man should have died in prison."
