Update: Police have confirmed that the plainclothes man going door to door at Oxford High School, was in fact a police officer, disputing assumptions that the school shooter was pretending to be a sheriff's deputy.

An exchange between the teacher and the believed shooter can be heard, where the teacher isn't willing to open the door.
