We'll have to determine what to do with the murderer now or it could easily spiral out of control, depending on who it is. We'd need to...hold or a trial or contain the murderer somehow. *Won't that be a giant pain in the ass when it happens? Because all they needed were reprisal murders.*

So we know what happened but we have no idea who did and we can only surmise the reason it happened was to either regain a memory or protect a secret. And by the way, there probably is something wrong with my brain because I can't come up with anything other than this.
