MILWAUKEE (WRN) - The man accused of attacking Milwaukee Mayor Tom Barrett is due back in court Thursday. A judge will hear final requests involving a trial for 20-year-old Anthony Peters. That trial is set to begin February 15th. Defense lawyer Anthony Cotton says he has not been able to discuss a plea deal with prosecutors, so he’s planning for a trial. Peters has pleaded not guilty by insanity to felony reckless injury and 3 other charges. Authorities said the mayor was leaving the State Fair in mid-August when he saw Peters fighting with the grandmother of his young daughter. And as Barrett called 911 to help the woman, officials said Peters assaulted the mayor – breaking a hand and causing severe head and facial injuries. His lawyer says Peters may be schizophrenic, and he has bipolar disorder. He was recently given a mental exam, and Cotton says he’s still deciding whether to challenge the results.
