Ranger Tucker Amiotte came upon a vehicle swerving badly between lanes as it headed north on Bombing Range Road on July 21st. When Amiotte stopped it, the driver – later identified as David Adair – got out and began walking towards him. Amiotte ordered Adair to return to his vehicle and stay there until he could speak with him. He did so, then accelerated back onto the road, made a U-turn, and headed towards the Pine Ridge Indian Reservation. Amiotte pursued while calling for assistance from tribal police officers. The pursuit continued for another 18 miles until Adair came to a spot where tribal officers had placed road spikes on the highway. One of the officers tried to stop him before he reached the spikes, only to have Adair aim his vehicle directly at him. Adair continued towards the officer, who was armed with a shotgun, and only veered away at the last moment. Adair then drove over the spikes. The vehicle, its tires pierced, came to rest in a ditch alongside the road. Officers and rangers arrested him without further incident. Narcotics were found in the car following the arrest. Adair was charged with reckless driving, DUI, attempting to flee and elude police, and possession of narcotics. Investigation indicates that narcotics were a contributing factor in the incident.
