DARLINGTON - A trial is called off for Jaren Kuester after he clammed up in court, again raising questions about his competency. The 31-year-old Waukesha man walked barefoot, shackled and wearing a suicide smock into Lafayette County Circuit Court Friday afternoon, Sept. 27. He is charged with using a fireplace poker in April to bludgeon to death three family members in a Wiota Township home, apparently in a random act of violence.
