On November 5, 1907, a violent confrontation erupted in Lexington, Kentucky, during a contentious Election Day. Officer Michael Murphy, a 49-year-old White / Caucasian male, was on duty near a polling place situated at the intersection of High Street and South Broadway. The political atmosphere was highly charged as voters cast their ballots for local offices. Tensions peaked when W. R.
Campbell, a Republican candidate running for a city council seat, began causing a significant disturbance at the location. Campbell was loudly alleging election fraud, screaming his complaints and disrupting the proceedings, which drew the attention of law enforcement on the scene.
When Officer Murphy attempted to arrest the councilman candidate for his unruly behavior, the situation escalated rapidly. As Murphy moved to take W. R. Campbell into custody, Campbell's son, Clyde Campbell, rushed forward to intervene and aid his father. The confrontation quickly devolved into a chaotic gunfight involving Officer Murphy, a fellow officer named Patrolman Marion Smith, and the two Campbell men. All four individuals drew their pistols and exchanged fire at close range in the street.
The exchange of gunfire had devastating consequences for everyone involved. Clyde Campbell was struck by bullets and killed during the shootout. Officer Murphy suffered critical gunshot wounds and was transported to St. Joseph Hospital, where he succumbed to his injuries at 10:00 p.m. the following day, November 6, 1907. Both W. R. Campbell and Patrolman Smith were also severely wounded but survived the initial encounter.
Following the deadly incident, W. R. Campbell was arrested and charged with the murder of Officer Murphy. The legal proceedings against the surviving Campbell were prolonged and indecisive. Over the course of the next two years, he was brought to trial three separate times in connection with the officer's death. In each instance, the juries were unable to reach a unanimous verdict, resulting in mistrials. Finally, in July 1909, the Commonwealth's Attorney moved to dismiss the charges, citing the futility of a fourth trial after three juries had failed to agree, and W. R. Campbell was released without a conviction.
