Judith Ott

A summer afternoon in Chicago's Grant Park turned to tragedy on August 13, 1973, ending the life of Judith Elaine Ott, a 28-year-old woman visiting the city from Seattle, Washington, with her family. Her death was the final, brutal act in a series of killings that had instilled fear in the city and would ultimately expose a history of systemic failures in the justice and mental health systems.

That day, Judith, her husband David, and their young child were enjoying the park. When Judith went into a public restroom, David waited outside with their baby. Moments later, he heard his wife's screams. He ran toward the restroom and saw a man with a bloody knife emerging from the door. Without knowing the full horror of what had just happened, David, with the help of park employees, chased down the fleeing man and held him until police arrived. Inside the restroom, Judith had been stabbed to death.

The man they captured was 51-year-old Lester Harrison, an individual with a long and violent criminal record dating back decades. At the time of the attack, he was out on bail for another assault. Harrison's history was a revolving door of arrests, short prison terms, and psychiatric hospitalizations. He had been found not guilty by reason of insanity for a 1951 murder of a fellow inmate and had been repeatedly released from custody despite clear signs of being a danger to the public.

In police custody, Harrison not only confessed to the murder of Judith Ott but also admitted to killing three other women in and around Grant Park between 1970 and 1973. His victims were Agnes Lehmann, 46; Judith Betteley, a 24-year-old architect visiting from England; and Lee Alexis Wilson, a 24-year-old art student. He provided investigators with details that only the killer could have known. A search of his apartment uncovered chilling souvenirs from his crimes, including victims' belongings and newspaper clippings about the murders.

Harrison’s confession had an immediate and profound impact on another man's life. Wilbur McDonald, a factory worker with no criminal record, had been wrongfully convicted of the 1970 murder of Agnes Lehmann based on circumstantial evidence and had been serving a 150-year sentence. Harrison’s detailed admission to the crime proved McDonald's innocence. Two days after Harrison's arrest, Wilbur McDonald was released from prison. He was later granted a full pardon based on his innocence.

The series of murders had terrified Chicago, with newspapers decrying the lack of safety in the city's "front yard." The attacks were characterized by extreme brutality, including sexual assault, beatings, and stabbings. Harrison's capture brought an end to the reign of terror but raised disturbing questions about how a man with such a violent and well-documented history of mental illness was repeatedly allowed his freedom.

Lester Harrison was never brought to a conventional trial for the murders he confessed to. Following his arrest for Judith Ott's murder, he was again evaluated by psychiatrists who diagnosed him as a paranoid schizophrenic. He was found unfit to stand trial. In 1978, he was formally found not guilty by reason of insanity and committed to a secure psychiatric institution under Illinois's Sexually Dangerous Persons Act, with the expectation that he would never be released. The case of Judith Ott and the other victims of Lester Harrison remains a tragic illustration of the devastating consequences that can result when the legal and mental health systems fail to protect the public from repeat violent offenders.
