Hello All,
I was walking home with my girlfriend after a night out and picked up some groceries (frozen pizza, pop etc) then proceeded home. We did have a few drinks but by now means were we intoxicated. As we were walking back her feet started to hurt and I offered to carry her on my back. There was a window sill extending onto the sidewalk and she suggested she get on there then on my back. As she is getting on a man comes to the window and starts yelling and screaming at us. I inform him that she is just getting on my back then we are on our way.
He then threatens me by telling me he has a gun and that he will shoot us. I proceed to inform him that it is illegal to own a firearm in the city of Chicago and that we are no threat and we are leaving. He disappears and comes back with a hammer waiving it at me through a window. At this point I try and grab the hammer in self defense. He stepped back and closed his window again. I inform him again that we are on our way and that my girlfriend is just getting on my back.
I turn around so she can get on and next thing I know I got struck with the hammer in the head and was able to prevent the second blow by putting up my hands. From there I instructed my girlfriend to call 911. I lost it at this point and tried to get to the guy by trying to break his window(unsuccessfully).
When the cops showed up I informed them of the situation but they acted as if I was to blame for the whole incident. They took my information and the ambulance then showed up. I do not know what happened after I left in the ambulance.
I was not on his personal property at any time and did not provoke this attack.
Do I have a case for assault? If so, what are the necessary steps I have to take to press charges?
I got 6 stitches in my head for no reason. I also took pictures of the wounds as evidence if need be.
Thanks!!
