The complaint indicates Brown did leave his vehicle -- and "took off running eastbound." While deputies began their pursuit, they saw "Brown produced a firearm in his right hand." The deputies gave verbal commands to drop the gun, but Brown did not comply. That is when one of the deputies released K-9 Riggs' leash -- and K-9 Riggs began a pursuit of Brown. It was at this point that Brown "fired one round behind him," the complaint says.
When K-9 Riggs got to Brown, both were seen falling to the ground. The complaint says Brown appears to "wrestle with K-9 Riggs," and then "discharges his firearm two additional times, striking K-9 Riggs." Deputies then returned fire, striking and injuring Brown, the complaint says.
