A teenager who was 10 years old when he fatally shot his father in 2004 in Katy has been sentenced to probation after pleading guilty to murder. The older boy, sitting in the backseat, shot his father through the back of the driver's seat with his mother's .45-caliber pistol. Lohstroh and his ex-wife, Deborah Geisler, had both been arrested on family violence charges on different occasions before they divorced, police reports show.
