A lawsuit against a Michigan State Police trooper who fatally shot an 18-year-old girl who was fleeing pursuing police in her car has been challenged by the Michigan attorney general's office. Tentative plans by the defense team are to have Wayne State University criminal justice professor Daniel Kennedy testify on behalf of the accused officer, who fired a shot into the suspect's car as she sped toward him to flee after being stopped by police. An attorney for the plaintiffs argues that Kennedy is not qualified as an expert and that his opinions on the shooting "at best constitute novel and untested theories." A hearing on the state's motion to throw out the lawsuit has been delayed by a circuit court judge until mid-October.
