Why it matters

The details

According to the report, the incident began when Grossklaus called dispatch requesting that his ex-wife be removed from his home. When the deputy, Cory Mass, arrived, the ex-wife said Grossklaus was "very drunk and mad at her" and had said he was "getting his gun ready." A struggle ensued when Mass saw the barrel of a shotgun and tried to gain control of it. Grossklaus then produced a small pistol, leading to a further struggle before Mass was able to pin Grossklaus' hand holding the gun against a door.
