C

As Joe and Michael were heading towards the Drivers License place, Michael, who was behind the wheel, froze as he heard the voice on the radio saying that a man had been murdered by a bullet that had came from the sky. He immediately drove off and went to a secret place. Later on that day, after thinking that the shot they had fired possibly wasn’t the shot that killed Mr Ward, they headed back to the Drivers License place where Michael failed the driver’s test because he could not think straight. For the next two months, Michael and Joe hid the secret that the bullet had actually shot Mr Ward.

During this time, Jenna Ward started to realize life without her father. While Jenna mourned the death of her father, a strange boy started to appear at the front steps of the church across the street from her house. After many nights of watching this boy, she finally recognized that it was Michael who was sitting on the steps every night.

After months of finding out where the shot came, the police were able to narrow the search area down to within a four-block area. Among these four blocks were Michael’s house and Joe’s house. When the police arrived at Michael’s house, his dad mentioned the gun that Michael had received from his grandpa at his birthday party. Michael, trying to be sly, told the cops that Joe had borrowed the gun. Upon this, Joe said that the gun had been stolen out of his car along with his CD player. After the police were gone, Michael met Joe at a special spot and told Joe the gun was under the wood pile in his backyard.

One day, when Michael thought the police would not come back, he came home to find the police searching his backyard with metal detectors. When the Sergeant(警官) went into the woods behind the house, he came out with a bullet that Joe and he had shot off on his birthday. The bullet matched the one that they had recovered from Mr. Ward, but without the gun, the police could not place Michael as the killer.

With the pressure mounting, Michael finally broke down and realized he had to give up. On a Saturday morning, he went to Jenna’s house to confess to her and her mother and then turned himself in.
