I'm not Chicken, LOL. But I do have a kid in that age range, one who is into the same hipster type lifestyle, bike riding, and attends many of the same events that Mickey and her friends attend.....my kid and Mickey's circle of friends have many friends in common.
So, from day 2, my son (the 21 year old) has been telling me it is stupid to hold out any hope. He bases his opinion on the fact that zero evidence was found of whatever happened to Mickey....so to him, that means someone had bad enough intentions to completely cover his tracks. He works with a couple of Mickey's personal friends, and they seem to be holding on to hope that she is being held by someone and will eventually escape or be released.
I think the young people of Lafayette are all over the board on this.
