What's particularly hard to understand for many right now is: if DE was so bright why would he commit such a horrendous crime basically in the face of LE, leaving an electronic trail a mile long that lead directly back to him. No one could possibly be that stupid to think cops wouldn't be at his door in under 30 mins once the girl went missing, much less a Virginia Tech engineering major. FBI was called in right away, same day, and all e-trails led right to DEs door. There's a lot that's not seeming to "add up" right now but it will all become clear once each suspect starts turning on the other and their statements become public. Also remember that if DE is as much of a perfectionist and high achiever as he is believed to be, it stands to reason that he would not take too kindly to an overweight 13 year old posing as a college student, trying to fool him. In fact I would even say this might be enough for someone like him to snap, particularly in light of the fact that she is known to fall hard and frighteningly fast over guys and threaten to kill herself if they stop talking to her. She might even fake a pregnancy. What if he got with her once in the dark in the park near her house, then found out her real age sometime later and tried to break it off. She was known to become suicidally head over heels "in love" with guys she only spoke with online.
