KANSAS CITY, Kan. (AP) — A Kansas City, Kansas, activist charged in the death of a pedestrian has filed motions challenging the charges and the legality of the Wyandotte County court proceedings.

The Kansas City Star reports Tamika Pledger is charged with involuntary manslaughter and aggravated battery. She’s accused of running into four teenagers Jan. 13. A 16-year-old girl died a week later from her injuries.

Pledger was running for a seat on the board of commissioners of the Unified Government in Wyandotte County at the time of the crash. She contends Wyandotte County officials don’t have jurisdiction to prosecute her and that a judge didn’t sign the affidavit to support the charges.

Wyandotte County District Attorney Jerry Gorman says he’ll comment on Pledger’s comments in the courtroom.

Her preliminary hearing is Oct. 29.
