I don't know what the bar-closing laws are in GA, but around here (New England), 2-3 am is the highest crime time of the day. It's right after the bars have closed. Drunk people heading home, prostitutes cruising them, drunk people getting in fights, drunk aggressive people breaking into their ex-girlfriend's house -- and this in such a low-crime area that there are still people who don't lock their houses.
A heart attack or pacemaker failure can fell you instantly. A friend of ours had a heart attack on the sidelines of a soccer game. The ambulance crew got to him within two minutes but they said he was probably already dead by the time he hit the ground. Or it can make you very disoriented. If it hit while he was in the parking lot at K-mart or something, he might have wandered off in the wrong direction thinking he'd find help there, or not knowing what he was doing.
