I have read some about Kyron, but I'm afraid he wasn't one that held my attention for very long. I really don't remember reading much about him personally at all, more about him being gone and the people who were involved in his life. I sometimes feel bad about that because there seem to be many people he touched very deeply; I'm not in any way saying he wasn't deserving of long term interest or every effort everyone has put into finding him.
With Jessica R., I can see her pretending to be a waitress with her family. I can see her making her lunch in the mornings to try to prove how grown up she was, but also turning around and enjoying snuggling with her mother/grandmother/aunt while drinking a cup of hot chocolate and watching a movie on a cold day . It's never been said, as far as I know, but it's the way I envision her. Seeing pictures of her with her dog, cheerleading, heading off to school, and all the other things just make her seem more "real" to me. To me, she was on that line between a sweet little girl and a responsible young woman. MOO
With Dylan, the friend's video was a big part of it. His mother and brother make it obvious that he was loved, but his father's sometimes less than glowing description makes him appear more real to me. Looking at his pictures and the video, I see a kid who loved being with his friends and being active. He strikes me as an outdoor/athletic person who is a team player. I can see him swimming, skipping stones, even building sand castles more than sitting quietly waiting for a fish to bite. I also see him as much more likely to "pout" or just mope when he doesn't get his way than to challenge the decision and argue about it. In my mind, I can actually see the morning he disappeared. Sleeping, waking up a bit when his father was bugging him to get up, and saying something like, "Okay, I get it!" and rolling over to go back to sleep when he was told it was his last chance to go in the morning.
Obviously, many people don't see things like I do, but the question was (I think) who do some cases hold your attention longer than others do. MOO
