The trial is scheduled to begin Monday for the former St. Louis police officer charged with gunning down his neighbor in an ongoing dispute.
Glenn Head was charged in the shooting death of 67-year-old William "Bill" Bacon.
Head is charged with second-degree murder in the Dec. 11, 2012 death.
Bacon died in the Northeast Regional Medical Center emergency room. The shooting occurred about 3:30 p.m. near County Road 312. A copy of the criminal complaint said that Bacon was shot in the chest.
An initial report said that Head and Bacon had an ongoing dispute over whether a county road was opened or closed. A probable cause statement filed with the criminal charges said that Bacon contacted the Knox County Sheriff's Office to complain that someone was trespassing on his property.
The Sheriff's Office received a second call of a shooting at the same location.
Deputies and troopers from the Missouri State Highway Patrol went to the scene where they found Bacon lying on the ground with a bullet wound in his chest.
Head told Sheriff Mike Kite that he had shot Bacon following an altercation, according to the probable cause statement.
