Three people were shot and one of them died after he was struck by a vehicle, shortly before 1 a.m. Monday in the 13000 block of Washburn, between Buena Vista and Fullerton.

Those wounded included a 54-year-old man grazed by a bullet and 26-year-old woman who was shot in the shoulder. The third person shot, police said, was a 29-year-old man who was then run over by a car and killed. No names have been released.

While police say it's unknown who fired the shots, investigators believe multiple persons of interest seen in security images may have information that can help the investigation.
