Arrangements for the trial have been complicated by Spates' decision to serve as his own counsel.
Spates' competency has been reviewed twice since the April 2002 shooting.
He also has had attorney after attorney appointed, for a total of six. Spates said none of his attorneys were representing him fairly.
Spates is not completely on his own, Presiding Judge Kurt Klein has appointed Kane County First Assistant Public Defender Regina Harris as standby counsel.
