A preliminary hearing scheduled to begin Monday morning will determine if F. Glenn Miller Jr. will face trial for allegedly killing three people in Overland Park last April.
Johnson County prosecutors intend to call about 15 witnesses to make their case against Miller, who faces a potential death sentence on the capital murder charge.
Miller, 74, also known as Frazier Glenn Cross Jr., also is charged with three counts of attempted first-degree murder, aggravated assault and discharging a firearm into an occupied building.
After the evidence is presented, District Judge Kelly Ryan will be asked to decide if there is probable cause to try Miller.
If the judge finds probable cause, Miller will be arraigned and attorneys will begin planning for a trial.
The shooting spree outside the Jewish Community Center and the nearby Village Shalom care center killed 69-year-old William Corporon and his 14-year-old grandson, Reat Underwood, and 53-year-old Terri LaManno.
Bullets fired at three other people missed their marks.
Police arrested Miller, who lived in Aurora in southern Missouri, nearby shortly after the killings. He has been in custody since then.
Although authorities have not publicly released details of the incident, Miller has made numerous comments in previous court hearings and gave a lengthy interview to The Star in which he said he had intended to shoot as many Jewish people as he could that day.
None of the victims was Jewish.
Miller has a long history of involvement in white supremacist groups, including forming a Ku Klux Klan chapter in North Carolina in the 1980s.
Johnson County District Attorney Steve Howe has filed notice that if the case goes to trial and Miller is convicted of capital murder, he will seek a death sentence.
