Now that some information about JM's early life is starting to emerge, it's not unlikely that his idea of "normal" intimacy between a male and a female is highly distorted. Maybe we'll learn whether his transition to killing his victims is part of MO, signature, or both. Did he kill Morgan, Hannah, and any others because they fought his attempts at very rough sex? Did he kill them because he got carried away? Or did he do so to get rid of witnesses?
