The protesters carried signs that said "Justice for Sam Dubose" Wednesday night near the university's Nippert Stadium, where fans were arriving for a soccer match. The protesters also were circulating petitions seeking the retrial of Ray Tensing, AP reported.

A mistrial was declared twice in the murder and voluntary manslaughter case of Tensing. He was a University of Cincinnati police officer when he shot DuBose during a 2015 traffic stop. Tensing says he fired in self-defense because he was being dragged by DuBose's car.

Hamilton County's prosecutor says he'll announce whether to retry the case the week of July 10.
