I've been thinking this over a lot. Since I don't like being wrong about things. And I'm really, really sure it's Person 5. Not only did he try to blame me—And Mr. X was someone I owed a big favor too! But he also talked about his body as a mess and said he could do a cleaner job and that he deserved to die. Those really aren't things a nice person would say about someone else. It's him for sure! I just hope you catch him so I can know I did a good thing for Mr. X.
