Bumping for Crystal.
I know that some people here speculated her brothers might have been involved, but I highly doubt it. Eye witness testimony, and memory itself, are incredibly fallible: I wouldn’t be surprised if the truth of what happened that day was some combination of the different events they recalled. Perhaps they were riding bikes together, then spent time tossing fruit into the neighbor’s yard, or vice versa; either way, I think an opportunistic predator grabbed Crystal in the minutes she was alone and away from her brothers.
Maybe it was someone who had been watching her for awhile, or merely a creep who happened to be in the area at the time. I can only hope that her remains will be stumbled upon, or someone will give up a piece of information that breaks the case open. Thinking of you, Crystal. May you be at peace, wherever you are.
