Frazier Glenn Cross, the former KKK grand dragon accused of killing three people outside a Jewish community center and a retirement community in Kansas City, Kansas, was once busted with a black transvestite prostitute, according to a new report.

The information was uncovered by WTVD-TV, while they were digging into the background of the alleged anti-Semitic gunman, who is also known as Frazier Glenn Miller.

Cross, 73, has been charged with three counts of first-degree murder in connection with the fatal shootings of two people at the Jewish Community Center of Greater Kansas City and one person at Village Shalom Retirement Community, in Overland Park on April 13. Authorities are expected to file hate crimes charges in the coming weeks.

According to the news station, Cross was arrested in Raleigh, N.C., in the 1980s, after police caught him in the back seat of a vehicle, with a black male prostitute who was dressed as a woman.

The two men were said to be involved "in a sex act" at the time of their arrest, WTVD-TV reported.

Former federal prosecutor Doug McCullough told the station he remembers the incident.

"It was pretty shocking because of his personal stances that he had taken," McCullough said.

The former prosecutor, who is now a judge, declined to elaborate on specifics of the arrest, but did say the details are "salacious."

Cross was not charged in connection with the prostitution arrest.

WTVD-TV also reported Cross, who served three years in federal prison in the late 1980s for weapons charges and for threatening a race war, had avoided a longer sentence in exchange for testifying against members of the White Patriot Party. Because of Cross' testimony, he was reportedly placed in the federal witness protection program.
