Wow! There are so many theories about the "whys" in this horrible crime. I find it hard to believe a guy would kill a young girl because "she was going to expose their relationship." The article mentioning this theory came out before the COD was revealed, so it is a few days old.
I do not feel there is a plausible reason why either accused perpetrated this murder, at least not to anyone who would ever be prone to kill someone over such a flimsy excuse. In other words, there were already very serious issues that defined DE's behavior as abnormal, making it impossible for a sane person to understand his motives.
The article above about disclosing the relationship is dated today, 507pm. It's the first I've seen of it, officially.
