DALLAS (AP) — A jury has found a former Dallas police officer not guilty of assault in the fatal shooting of a 21-year-old woman in 2017. The Dallas County jury returned the verdict Thursday in the trial of Christopher Hess. He was charged with aggravated assault by a public servant in the killing of Genevive Dawes. Hess shot a dozen times into a car as Dawes reversed the vehicle into a police cruiser, rammed a fence and was backing up again when the officer opened fire. Prosecutors argued that his actions were unreasonable. His attorneys said the shooting was justified because the car presented a threat.
