ARLINGTON, Texas — An unarmed, black college football player tried to smash through the locked glass door of a North Texas car dealership showroom to escape an officer in training, then turned and headed toward the officer and was fatally shot, the police chief said.

Called to the scene of a suspected burglary last week, officer Brad Miller pursued 19-year-old Christian Taylor into the showroom without telling his supervising officer, Arlington Police Chief Will Johnson said Tuesday as he described the encounter.

Johnson said Miller, 49, has been fired for causing a deadly confrontation that put him and other officers in danger.

Inside the showroom, Miller ordered Taylor to get to the ground. Instead, Taylor cursed at the officer and advanced toward him. When Taylor was about 10 feet away, the officer fired, Johnson said.
