Yeah, he went to Walmart, then sat down and ate at McDonalds. Then he was walking towards home. If you're on the run, that's not a typical plan of action for evading.
I don't think they reported early… they were set up, meaning they were ready to go as soon as the event started. They were on scene and ready to roll cameras.
There was also video that included that body. Then that class was led downstairs and there was few more in the floor level hallway before they reached the door. It went by quick so wasn't any detail.
