A Broken Girl In A Perfect World

I was running down a long dark alley, it was pitch black. All I could see was trash cans from the street lights. I could here some one chasing after me but who? All of a sudden the noises behind me completely stopped. I stopped. Looking around i see a man in a mask on the ground just laying there. Was he hurt? What do i do?
I pulled out my phone and dialed 911.
"Hello? a man is hurt i need help!"
