In July 2020, Sgt. Sean Collinson was involved in a fatal shooting during a welfare check on Douglas Diamond, a retired Washington County Sheriff’s deputy. Collinson, along with other officers, approached Diamond’s RV and, after a series of events, Collinson tackled Diamond, leading to Officer Michael Boyes shooting Diamond, resulting in his death. The family filed a lawsuit alleging civil rights violations, claiming the officers made fundamental tactical errors and failed to abide by standard use of force training. The city and county have claimed qualified immunity in response to the lawsuit.
