Judith Ott, 28, was murdered on August 13, 1973, in a restroom at Grant Park in Chicago while visiting the park with her husband David Ott and their child.

Harrison reportedly had a long criminal history and prior findings of not guilty by reason of insanity going back to a 1951 murder. After his arrest he confessed to Ott’s killing and to several earlier Grant Park murders, leading to the exoneration and eventual pardon of Wilbur McDonald, who had been convicted in one of those earlier cases. Because Harrison was again found incompetent to stand trial, he was committed to a mental health facility rather than sentenced to prison.

Are there readers who remember Grant Park in the early 1970s or who can add details about the aftermath of these cases?
