When I left my office, I already had a premonition that something awful was going to happen that evening. I’m not psychic. I am quite perceptive, though, and the signs were easy to read. I had worked late – nine o’clock and already dark – and my ordinarily enjoyable walk to the parking lot struck me as a little bit menacing. I parked in a lot that was about a ten-minute walk from my office. In the early evening on a crisp autumn day, it’s a pleasure to stroll there and take in the sights of downtown Indianapolis. Occasionally I’d take a detour and walk along the canal, checking out the street art. This was past nightfall, though, and right in the middle of a hot and humid August. There were only two sorts of people in downtown Indy that night – those who had to be, and those who had no place else to go.
