I have a theory (idk if I could call it a theory) that Richard is the one who killed Arthur's (the manager) lover. Since Arthur said it was a from long time ago, it might be the possibility that Arthur's lover did suicide because of Arthur and how much he enjoyed it.

@Blu3 Hmmmmm. Interesting theory. 
@Blu3 I don't think it's about how much he enjoyed it. Probably how much he hated it.
