Also, if Sherlock chooses me for the killing, I choose to kill meme. Well, to be fair, I won't actually kill her.
Instead, I'd like for the group to wonder where meme is, and go to her room, to find her door locked. Then, they'll hear her say "please, someone help me" from inside, so they'll force the door in. Upon forcing the door in, they'll knock over a stool with a pumpkin on it. They'll see meme laying on the opposite side of the room, with her hands and feet bound, with tape on her mouth and a noose of razor wire around her neck. As the pumpkin falls from the stool, it pulls the wire that it is tied to, causing the razor wire to pull up, slitting her throat. Then meme dies, technically not by me. :V
Then, the people will notice a tape player on her bed, which is repeating "please, someone help me... please, someone help me...".
