Radio traffic released by authorities indicates that a North Carolina state trooper chasing a deaf driver reached speeds of up to 100 mph before the driver was shot and killed in sight of his Charlotte home.

The conversation between Trooper Jermaine Saunders and the dispatcher also indicates the officer intentionally wrecked Daniel Harris' car to try to stop the chase before it left Interstate 485, but the pursuit continued.

The radio traffic released Tuesday doesn't include any interaction between the driver and trooper, who was trying to stop Harris after clocking him going 88 mph in a 70 mph zone. The trooper also doesn't give a reason he fired at Harris on Aug. 18 after reporting Harris was running away.
