AURORA, Colo. (KDVR) — There is a new push to solve the killing of a 13-year-old boy.

Phoenix Day was gunned down in the parking lot of the Town Center at Aurora mall back in March, and no one has come forward with information to help bring closure to his family.

Police released photos of several people they believed to have been witnesses and could know exactly what happened. The photos depict a total of 16 witnesses.
