Evidence shows that a white University of Cincinnati police officer was wearing a T-shirt with a picture of a Confederate flag on it when he fatally shot an unarmed black man last year.

A photo of the black T-shirt with the flag and the words "Great Smoky Mountains" was presented during a crime scene technician's testimony Friday at the trial of since-fired Officer Ray Tensing.

Tensing contends he was dragged by the car driven by victim Sam DuBose. A prosecution expert witness says Tensing's body camera video of the shooting contradicts his argument.

A use-of-force expert hired by the prosecution testified DuBose didn't present a threat to Tensing at the time of the shooting.
