On a cold December night in 1997, Memphis Police Officer Don Williams was working off-duty as a security guard at a comedy club when he ejected a man from the establishment. The man later returned and, at point-blank range, opened fire on Williams. A single bullet tore through his neck, severing his spinal cord and leaving the 38-year-old, 16-year veteran of the Memphis Police Department paralyzed. He died of his injuries on January 29, 1998, and left behind a wife and three children.

The investigation led to the arrest of Timothy McKinney. In 1999 McKinney was convicted of first-degree murder and sentenced to death, but an appeals court granted a new trial because of ineffective counsel. Retrials ended in hung juries. In May 2013 McKinney pleaded guilty to second-degree murder, was sentenced to time served and released after more than a decade behind bars. Less than a year later he was arrested for shooting a 14-year-old in North Memphis and in January 2016 was convicted of attempted second-degree murder; under Tennessee’s three-strikes law he received life without parole.

Are there witnesses, family members, or others with memories of Officer Williams or that night who can add details to the case?
