When I was in college, a friend of mine had his room broken into from outside of the hall where we all lived, and the thief stole all of his most expensive items in the room. The funny part is that the thief seemed to know where everything was in his room.
We found most of the things in a local pawnshop close to the hall where we lived. We ended up catching the guy and it was a kid that my friend counted on as being a friend to him. He was always in his room and knew everything in his room and stole him bind. He was screwed over by a so call friend and I could see things weren't always right with the dude who was the thief. Moral of the story, if you think of someone who seems like he might be shifty, he probably is shifty.
