The North Carolina Highway Patrol is urging people to not jump to conclusions as state agents investigate how a deaf driver with a history of minor offenses ended up dead after leading a trooper on a 10-mile chase.

State Department of Public Safety Secretary Frank Perry says the investigation into last Thursday's shooting is ongoing.

The family of Daniel Kevin Harris says he was unarmed and suggests the sequence of events last week was a tragic misunderstanding.

Authorities haven't said why Trooper Jermaine Saunders fired.

A review of public records shows a few traffic and other minor charges against Harris from other states, including a Denver police report that says he damaged his employer's vehicle with his own car after he was fired last year.
