No, I didn’t hear Chief Harper at 6, so I didn’t know that his story had changed.
His story didn’t ‘change’ it was expanded upon. They now have the autopsy results from the dog (he was shot by the gun fired by Jackson at the dog and at the two Pittburgh Police Officers). They also had the time to trace the gun (via serial number) and found that is was infact a stolen gun. Again...more facts have come out...no ‘change of story.’ It is an ongoing investigation.
