Dude, i feel your pain. That has happened to me. I came out in the morning to find my window broken, my door wide open and my alpine gone. Fiiled a report and the cops called me a few hours later and said they caught someone who admitted to doing it. Whe I went down to the station, they told me the two kids were out all night and hit 13 cars in the neighborhood... They were also strung out on crack.. Come to find out, it was two kids that I went to high school with.
I was really P!ssed at first but didn't press charges as they were already in a whole heap of trouble and Civil Court wouldn't have got me jack squat.... I did see one of the kids a few years later and confronted him. He apologized and said, "He was wacked out on drugs, severed his jail time and was now clean and trying to get his life straight... I let him off the hook and wished him good luck...
I know... Bad ending of the story huh?
