Murder?

I was pretty good until my injury. I was even college-bound. Now all I do is watch, sit and watch. I always feel restless when I watch. Its a feeling of desire and want that is more emotional then physical. Out there I had everything. I was everything. I sat and watched until there was only one man left. Then there was no one left. Just me and this place that is so familiar but distant. I start to walk out there sensing a faint feeling that is fading quickly as I realize the pointlessness of my pursuit.

I turn and head back and see someone out of the corner of my eye. They seem to be running towards the abandoned building to my left. There is someone chasing them. The dark figures move quickly. Dashing under a streetlight I can make out the first man. It was the man who just left. Still in his white tshirt and shorts. The man chasing him was wearing a simple zip up hoodie and either a blue or black shirt with some white writing on it and jeans. He was holding something in his left hand that reflected in the light. He followed the first man into the building. I hear a sort of banging and crash. Seconds later the man wearing the hoodie comes out with his hands in his pockets and looks around briefly then casually walks away.
