According to a shooting summary released Wednesday, South Dakota Highway Patrol Trooper Mike Bock was justified when he shot William Chandler, 27, last month.
According to the report done by the Division of Criminal Investigation and State Attorney General Marty Jackley, Trooper Bock shot Chandler after a high speed chase on Interstate 90 that began in Boulder Canyon and ultimately ended in the parking lot of Butler Machinery on Deadwood Avenue.
Bock and other law enforcement officers pursued Chandler after he was clocked going 80 miles per hour in 65 mile per hour speed zone. According to the report, they pursued him for nearly 20 minutes before a trooper intentionally collided with Chandler's vehicle to end the pursuit, which became increasingly dangerous when Chandler began heading west on the interstate into oncoming traffic.
Once the vehicle crashed, Chandler and his passenger ran from troopers. They were both caught. Chandler was handcuffed and placed in the back of a patrol vehicle. Dash cam video shows he was able to slip one hand out of the cuffs, get in the front seat of the trooper car, drive forward and then once he hit a dead end he backed up. He was heading in the direction of Trooper Bock and Trooper Chris Regan. Trooper Bock then shot Chandler, hitting him in the face. The report says Chandler was then tased when he refused to get out of the vehicle.
A toxicology report showed Chandler had THC Methamphetamine, Amphetamine and alcohol in his system.
