Long story short, Last night my girlfriend moved out to her new appt. On the last load of stuff, I decided to head out. Her father was over too helping and decided to leave the same exact time as me. Soon as I stepped out , I herd a Mustang idling outside , when I peaked around the corner, under the street light I seen this black guy around the age of 18-25 with dreadlock/braids (very long, like lil wayne) trying to either slim jim or do somthing to my lock, I run back inside tell my girlfriend to call the police and grab a hammer that I was using early that day to hang curtain rods. I go back outside and walk straight toward my car as if im on a mission with her dad, the guy inside the mustang must have see us way before the guy trying to break into the car does and takes off , he leaves his friend right there. I asked the guy what are you doing, before I ended finished my sentance he takes off, I tryed running after him but this dude could fucking run like no other. either way I wing the hammer as hard as I could with the intention to try and maybe scare him, either way the hammer bust him in the back of the neck/head area and he falls and slides in the middle of 8th street like a baseball player, and he screams like a girl......he gets right back up and cuts through some peoples yards, and I just gave up. Cops never catch either of them but said he might end up going to the hospital ( this hammer hit pretty damn hard and made the most nasty noise, when it hit the skull, I know he was bleeding pretty good).......either way first time I get to acually pay back the people that break or steal my stuff, I know it was not right in what I did but it sure felt good. this is the 5th time in the past year someone has tryed to steal my shit or break into either our cars or my parents house.
