Christopher Michael Grau, 48, was shot to death outside a motorhome in Firestone on July 5, 2019, after trying to defuse a family dispute. Grau had been at a house in Lakewood with his girlfriend, her brother Kenneth Hoschouer, and Hoschouer’s wife when an argument about the wife’s teenage daughter’s relationship escalated. Grau drove an intoxicated Hoschouer to the motorhome on Weld County Road 28 in an attempt to calm him; shortly afterward Hoschouer shot Grau in the head. Firestone police found Grau’s body the next day with thirteen shell casings nearby.

Police arrested Kenneth Hoschouer in September 2019 after a gun was recovered concealed in a vent at his residence. A Weld County jury later convicted Hoschouer of second-degree murder in November 2021. An appeals court subsequently ordered a new trial, concluding the jury should have been permitted to consider self-defense given evidence such as a pocketknife and a blood-stained wooden board found near Grau’s body that could indicate a struggle.

Did anyone who knew Christopher or his family see signs the situation might escalate that night, or have information about the events at the motorhome?
