""This guy was very eccentric," the co-worker said. "He was so detail-oriented. If he had a free minute, he would start doing origami. The things that came out of his mind were so original and creative, you knew that his mind didn't work the same way as normal people. But you worked with the guy so long, that you just chalked it up to Jeff being Jeff."
This morning, a report in the New York Times shed more light on Jeffrey T. Johnson, the man authorities say shot and killed his former boss near the Empire State Building Friday before he was gunned down by police. Nine others were injured by police bullets."
