In the Google Maps image, you see him clearly: Sitting cross-legged on the sidewalk at the intersection of Division and Sharp, huddled behind a cardboard sign asking for help. Steven J. Hackett was a fixture at that corner, so it’s only fitting he’s a part of the map. But he won’t be at his regular post any longer; police found him dead in an alley behind a nearby liquor store Monday. It was the kind of heartbreaking end his father had feared for Steven, after years of addiction and living on the streets.
