OLATHE, Kan. (AP) — Jurors are set to hear closing arguments in the case of a white supremacist charged with killing three people at two Jewish sites in Kansas.

Deliberations are to begin after closing arguments conclude Monday in the capital murder trial of Frazier Glenn Miller.

The 74-year-old Missouri man is acting as his own attorney and told jurors Friday that the prosecutor had a “slum dunk.”

Miller has admitted that he drove to two Jewish sites in Overland Park, Kansas, in April 2014 with the intent of killing Jews. He has pleaded not guilty because he says Jewish people are committing genocide against the white race and it was his duty to stop them. None of the victims was Jewish.

If convicted, Miller could be sentenced to death.
