The day Cooper died, JRH made plans to go to the movies, told his friends he did not want to go to lunch so he could leave work early, but went to lunch anyway since someone else drove, he not only went to lunch but spent time picking up light bulbs, and on top of that re-scheduled a meeting for 3:30pm right before he would need to leave for the movies? It sounds like JRH scheduled his day to rush out the door and hurry to drive somewhere else, but not before telling Home Depot security his plans for the first time since he's been employed.
He might have told a co-worker he was planning Cooper's birthday party, but it was only hours after he told someone else he needed to escape his son. smh
