Halloween Spooktacular

One day, I was at my house when I heard a knock at the door. It was Halloween, probably just an innocent kid wanting candy. I opened the door, when I noticed a little child, maybe 4’5 or 4’6 staring back at me. I asked her if she wanted any candy, (I knew it was a girl from her long, dark ragged hair). She said she needed my cellphone to call her mom to come and pick her up. I didn’t think anything of it, I thought she might have gotten lost. The only weird thing was she wasn’t dressed up. She wore a pink Hello Kitty shirt and a pair of blue jeans and a pair of all-black sunglasses, despite the fact that the time was almost 11 o’clock at night. She was so small and frail, I mean, I couldn’t leave her out there all alone. I gave her my cellphone and she suddenly asked me if she could come inside, even though she never even dialed a number. I mean, she can’t hurt me, right? I still wasn’t comfortable with letting her inside, so I politely declined. She suddenly started to cry and said that I was an awful person for not letting her in. Aw, I should let her in, so I did. She suddenly sprinted to the kitchen and grabbed a knife. I didn’t have time to call the police and I just stood there in shock when I noticed her all-black eyes. On October 31st, 2013, there was a murder at 1291 High Street, and the victim had no eyes in her sockets and was stabbed 73 times in the heart. Legend says, the child took it, so she could see again. The murder has never been identified, who says it couldn’t be me?
