I saw the headlines for my mom’s murder and knew I had to do something. So I went to the site to look for clues, and I found some fingerprints. I got them tested and compared them to everyone who knew my mom. None of them matched, so it must have been a stranger, maybe after her money. He might have not taken anything because my dad scared him. I went back to the house and found cat hair. My dad’s allergic to cats. So I found a list of cat owners, and talked to all of them. They all had good alibis, except for one-John Doe. He couldn’t get support that he was at home. I tested my lie detector on him, and knew he’d been lying. He had been in my mom’s house. But then I learned that he was my mom’s boyfriend. I was shocked that my mom had been cheating. He told me to test my own fingerprints. They were the same as the murderer’s. It was me who killed my mom. John explained that I got angry at him, so I thought that was who I killed. I didn’t remember anything. That must be why I’m here in a straightjacket now.
