A white supremacist charged with killing three people at Jewish sites in suburban Kansas City spent more than two hours on Friday 28 August telling jurors how he planned the attacks. Frazier Glenn Miller Jr, 74, of Aurora, Missouri, added that regretted that he did not kill more people.

Miller, the former leader of the North Carolina White Patriot Party, who is acting as his own attorney, called himself to the witness stand. He explained he felt compelled to carry out the murders because Jewish people were trying to wipe out the white race.

The former member of the Ku Klux Klan spoke of his military background. He also told jurors that the prosecutor had a "slam dunk" and knew they would put him on death row.

Prosecutors rested their case Thursday morning, barely four days into a trial that they had predicted could last three to four weeks.

Miller is charged with killing William Corporon, 69, and Corporon's 14-year-old grandson, Reat Griffin Underwood, outside the Jewish Community Center of Greater Kansas City in Overland Park. The pair were there so the teen could compete in a singing contest. Minutes after that shooting, Miller gunned down Terri LaMano, 53, at a nearby Jewish retirement home.

Miller said the killings were justified, and that his only regret was fatally shooting the 14-year-old. However, under cross-examination, Miller admitted that he would have been OK with killing Reat if he had been Jewish.

He said he murdered the other two because they were Jewish sympathisers, adding that he thought the prosecutor and judge also associated with Jews.

After a nearly three-hour lunch break, Miller returned to the stand and accused the judge for not allowing him to present evident explaining his mindset at the time.

He described having an emphysema attack just 10 days before the April 13, 2014, killings and explained his desire to "take out" Jewish people before he died.

The Vietnam veteran said initially he was unsure whether he would have the courage to carry out the attacks, but afterwards felt a sense of victory that dwarfed even the feeling of jumping out of airplanes when he was in the Army.

Miller is also charged with the attempted murder of three others. If convicted of the killings, he could be sentenced to death. Closing arguments will begin on Monday.
