Read about his pursuit of hawks in Central Park in great detail before the posts disappear. It's interesting that he was doing this just the day before he went to kill his former co-worker.
The photographs are pretty lousy for someone who, based on his job, you would think would know how to use Photoshop. I think this guy is pretty talentless actually. Based on his t-shirt art and his photography, he was probably fired because his clothing designs sucked.
The blog in question is run by someone else, but Jeff appears to be the primary contributor. I guess he had lots of free time to wander around Central Park looking for hawks given that he didn't have a job to go to. Clearly his super was wrong about him spending all his time alone in his apartment. He was often about Central Park taking pictures of birds.
At this news article, you can see a photo of Jeff Johnson out in Central Park with his birding gear. You can see that he’s wearing his signature khaki suit. He doesn’t look as nerdy in this outfit as I thought he would, but it’s definitely not what I would wear in June in Central Park.
