Thank you! I agree, and I admit that I am having trouble with the "she couldn't have had a boyfriend because she seemed so nice and young". For starters, none of us actually knew her. Also, you can be a sweet, smart, YOUNG, sheltered, girl and still form online relationships or develop crushes on older boys. I feel like people are acting that this implication is somehow sullying her, but it's not. IMO, it would be rather normal. At 13 I still played with Barbies, slept with stuffed animals, and hadn't even had my first kiss. I was also a straight A student. And yet I was head over heels for the 18 year old Elvis impersonator (don't judge) my mom tutored. And he kind of liked me. In hindsight, my goals were sweetly innocent (rather than sleeping with him, I fantasized about holding his hand) but the feelings on my end were still real. I was a "good girl", yet I still hid things from my mom. It was fun at the time.
I agree that LE would probably have uncovered something by now, but there are lots of things they haven't told us. Speculating that she may have had a secret crush or an online bf is not insinuating anything dark about her. I think it would make her fairly normal.
