LACROSSE, Wis. — An insanity plea worked for Zachary Fritz, who was charged with killing his wife — 60 stab wounds — in their suburban Shelby home. Judge Elliott Levine ruled that Fritz was mentally ill at the time. Fritz is now headed to institutional care rather than prison. After the verdict his attomey, Christopher Zachar, told reporters that the case was “tragic” and “awful” — a situation in which “nobody wins.”
