The attorney for a Wisconsin man accused of killing an Illinois woman in an interstate drive-by shooting says the man has significant mental health issues. Zachary Hays, 20, appeared in court Thursday in Sauk County, where he faces one count of first-degree intentional homicide and three counts of reckless endangerment. Hays is accused of killing Tracy Czaczkowski in a May 1 drive-by shooting as she returned with her family to Illinois from Wisconsin Dells. Hays' attorney, Jon Helland, told reporters that Hays obviously has "significant mental health issues." He said they're exploring all avenues for defense, including competency. Hays also faces one count of first-degree reckless homicide in Milwaukee County, where investigators believe he shot his neighbor the morning of the drive-by. Judge James Evenson set a July 15 hearing.
