A Missouri white supremacist has pleaded not guilty to charges that he gunned down three people last year at Jewish sites in the Kansas City area.

Seventy-four-year-old Frazier Glenn Miller entered the pleas Friday during a court appearance in Johnson County, Kansas.

He was ordered earlier this month to stand trial on charges of capital murder, three counts of attempted first-degree murder, and one count each of aggravated assault and criminal discharge of a weapon at a structure.

Prosecutors plan to seek the death penalty if Miller is convicted.

Miller has said he felt a duty to kill Jews before his death, which he believed to be imminent because he suffers from emphysema.

A judge Friday denied Miller's request for Internet access while he's jailed awaiting trial.
