On the evening of October 5, 2016, 60-year-old Richard Paul Gibeau was shot and killed at a home near 2151 Watertown Place in Clarksville, Tennessee. Police were called shortly before 5:30 p.m.; officers found 27-year-old Joshua Chambers kneeling in the driveway, and a loaded 9mm pistol was recovered there. Statements led officers to the backyard where Gibeau was found and pronounced dead.

Investigators say an altercation began inside the house between Chambers and Gibeau and continued outside, ending with Gibeau being shot in the driveway. Chambers surrendered at the scene and was booked on criminal homicide charges; the original first-degree premeditated murder charge was later amended to second-degree murder. A jury convicted Chambers of second-degree murder in July 2018 and he was sentenced to 18 years in prison. The case was later remanded for a new trial on grounds related to jury instructions about self-defense.

Does anyone have information about the altercation inside the house or witnessed the events at that address on October 5, 2016?
