On the night of April 13, 2019, 29-year-old Cowlitz County Sheriff’s Deputy Justin Derosier responded to a report of a disabled motorhome blocking Fallert Road near Kalama. Around 10:00 p.m. he radioed that he was being fired upon. Responding officers found Derosier with a gunshot wound, moved him to a safe location, and he was airlifted to PeaceHealth Southwest Medical Center in Vancouver, where he died shortly after midnight.

A large manhunt began immediately. The next night, officers located 33-year-old Brian Dellaann Butts near Spencer Creek Road in Kalama; when confronted he opened fire and was killed in a shootout with police. Investigators later connected Butts by family relation to a man who had murdered a police chief in Oregon in 2011. The inquiry into Derosier’s death also resulted in arrests of two brothers, Matthew and Michael Veatch, and an arrest of Ricky Roberts Jr., alleged to have provided a getaway car for Butts.
