On May 31, 1990, Deputy Glayton Mitchell Parker, a 58-year-old white male with the Sullivan County Sheriff’s Department, was killed in Anderson, Tennessee while attempting to serve a misdemeanor warrant for a man who had failed to appear for a court-ordered mental evaluation. The suspect shot Deputy Parker in the face with a high-powered rifle, killing him at the scene.

The suspect was arrested and, after more than two years of mental evaluations, was found competent to stand trial. A jury convicted him of first-degree murder and sentenced him to life in prison. Two years later that verdict and sentence were overturned and the defendant was found not guilty by reason of insanity; he was committed to the Lakeshore Mental Health Institute. Deputy Parker was survived by his mother and two children.

Did anyone in Anderson at the time have contact with Deputy Parker or information about the warrant service that could help clarify the events leading up to the shooting?
