OLATHE, Kan. (AP) — A white supremacist accused of killing three people last year at two Jewish sites in Kansas is due in court for another hearing in the run-up to his August capital murder trial.

Frazier Glenn Miller Jr. got permission last month to fire his attorneys and represent himself during a contentious hearing in which he repeatedly interrupted Johnson County District Judge Kelly Ryan.

The hearing Wednesday will focus on two motions from Miller: one asking a judge to let him stay in the courtroom during recesses and another to suppress certain evidence.

The 74-year-old Aurora, Missouri, man has told several news outlets, including The Associated Press, that he is dying from emphysema and that he went to the sites in the Kansas City suburb of Overland Park to kill Jewish people.
