stormbreaker

the book i am reading is called Stormbreaker. It is about a boy named Alex Rider and he is 14 years old. He lives with his uncle. Early one morning the police were outside his house and they were investigating. Alex finds out that his uncle has been killed in a car accident. At first he is shocked and he never really shows much emotion. His uncle is a lawyer and his death took Alex by surprise. One day Alex was riding his bike past a junk yard and he goes in and curiously walks around. It is a car junkyard and he sees some cars being smashed for scrap metal. As he watches the cars being destroyed he notices a BMW that looks just like his uncles. Alex walks closer and realizes that it is his uncles car that he was driving while in the car wreck. It kind of makes him feel gross to see the car that his uncle died in. As Alex was in the car looking around he noticed something very strange, there were bullet holes all throughout the windshield of his uncles car...why?
