Middle School Murder

I hopped off the bus. My hands shook. I look up and read a sign that wrote "Welcome to Thayer J. Middle School!" The first couple of periods were fine. I was in gym and I heard a scream from the locker room. Everyone rushed to the girls locker room. The teacher entered first and we all followed. We all covered our mouthes in shock. We saw a dead body with blood dripping from it. It was the body of young Amy Bloom. I backed up because I have homophobia. The teacher told me to run the the office to call the police. The only question was, who did it?
