The man who wanted to kill Jews because they have “too much power”, and who admitted to killing three people outside two Jewish centers in Kansas City last year, was on Monday convicted of murder and other charges.

According to CBS News, it took the jury of seven men and five women just over two hours to find Frazier Glenn Miller, who also goes by the name Glenn Cross, guilty of one count of capital murder, three counts of attempted murder and assault and weapons charges.

After the verdict was announced, Miller, 74, of Aurora, Missouri, said, "The fat lady just sang" and, as jurors were filing out of the courtroom, he told them, "You probably won't sleep tonight."

CBS Kansas City reported that Miller also gave the Nazi salute as jurors left the room, prompting the judge to admonish him. Miller said he was disappointed and the verdict ruined his day.

The jury will now deliberate the sentence for Miller, who could face the death penalty.

Miller had been representing himself after firing his lawyers in May.

During the prosecution's closing, District Attorney Steve Howe cited a "mountain of evidence" against Miller, who was charged with capital murder in the April 2014 shootings at two Jewish sites in Overland Park, Kansas.

Although he has admitted to killing the three people, he pleaded not guilty, saying it was his duty to stop genocide against the white race.

None of the victims were Jewish and, in an interview last November, Miller expressed his surprise and regret at not having managed to kill any Jews.

The Passover eve shootings killed William Corporon, 69, Corporon's 14-year-old grandson, Reat Griffin Underwood, at the Jewish Community Center in Overland Park, and Terri LaManno, 53, at the nearby Village Shalom retirement center.

During his closing, Miller said he had been "floating on a cloud" since the killings. Earlier, he objected when Howe alleged he wanted to kill as many people as possible. Miller interjected, "I wanted to kill Jews, not people."

Miller urged jurors to "show great courage" and find him not guilty, according to CBS News.
