My Creepy Ex-Girlfriend

So I was watching TV until I heard banging from upstairs. So I went to check what that noise was. I grabbed the closest object, which was an umbrella, and crept my way upstairs. I didn't turn on any lights so that the intruder didn't know I was here. After a couple minutes of searching, there was absolutely nothing in any of the rooms. Then I went to check the cameras in the garage. I clicked through all of the cameras and saw my ex-girlfriend with a ladder trying to get in my room. She ended up breaking the window and got in. I was too nervous to be alone because she was crazy so I called my best friend, Devin. When he got here I checked the cameras to see if she was still here. I went through every camera and saw that she left when Devin pulled up. So the next day I called my landlord and he said that he would see what he can do. A couple days later, my window was fixed. "Whenever you need help just call me." Devin said as he left the house. Ever since then, I never went into my garage until I started to smell something horrible. I tried to find out where it was coming from and found out that it was from the garage. Since Devin wasn't answering I went in by myself. I opened the door and saw Devins ice cold body sitting right in front of me. His eyes looked so milky. I wanted to scream but I was in shock. He had to be there for a while because all of the blood on him was dried. When I got my nerves back, I called the police. After a couple minutes of waiting the police finally arrived. Then the cops told me I was going to jail for the murder of my best friend Devin Gomez.
