Robert Rockefeller, Michael Demith and Michael Demich are all aliases of an unknown elderly man who was discovered lying off the curb of an exit ramp off Lake Shore Drive with a shopping cart full of spoiled food, in a non-lucid 'altered' state with a possible heatstroke.
Due to this, he was hospitalized for treatment and became a ward of the state. Following his treatment for heatstroke, he was admitted into a Northlake nursing home. He is described as having an "altered mental status" and being "disoriented to person, time and place,".
Prior to becoming a ward of the state, he had been arrested multiple times, and for each arrest gave a differing name.
