DALLAS — A Dallas police officer charged with aggravated assault in the fatal shooting of a woman in a January confrontation has been fired.

Police say Christopher Hess was fired at a Wednesday hearing. Police say an internal affairs investigation found Hess violated the department’s felony traffic stop policy, use of force policy and placed a person in greater danger than necessary.

Hess was charged last month in the shooting of 21-year-old Genevive Dawes. Police have said Hess and another officer were responding to a suspicious persons call when Dawes allegedly ignored commands to exit her car, reversed into a police cruiser, rammed a fence and was reversing away when police fired.

Hess can appeal the firing. A call to an attorney representing Hess on the felony charge wasn’t immediately returned Thursday.
