It started then the day after Christmas,someone car jack a car ,in front of all places a police station . And no one saw who did it . There was a clue a piece of hair but even DNA scan found nothing who the hair belong too .But then there was a break in car jacks and it was quiet for the next several days or so.
 

But this then  time the police were ready,or so they thought they were ready a car was left a block or so away from the police station,it was in the afternoon in broad day;ight and still it was car jack and only a piece of  hair was found .Nearby a then  lot was filling fast with cars and the owner was trying too sell them but unfortunately for him a police officer off duty came too buy a car for his son ,but the owner did not know that the officer bought the car took it home the minute he tried starting it he saw a piece of hair there they examined it we need help
 

Still then the  car jacks continue  only then one  hair piece as evidence ,who did the piece of hair belong to and car jacking ,who was doing it  ? Or what was their reason for doing it though .Was for money the cars that were jacked wouldn't have been worth anything combine .
 

So who did this ?
 

( stealing is wrong for no matter what reason,its wrong )

one shot idea .
