@cherrymeg and I spoke on the phone yesterday, and she has brought some interesting perspectives to my attention.
@Missouri Mule, I agree with you, but I just do not know what to make of certain aspects of this case. I personally don't see rape being the motive or Sherrill being the target. Cherrymeg and I also both agree that there's something about this case that makes it feel as though the answer should be obvious. Like there's just one clue missing to answer everything. That's what sucked me in. Also the endless possibilities of what could have happened.
If anyone else is interested in speaking over the phone about this case, just let me know. I'm currently working on a podcast of this case. I want it to be heavily detailed so It'll probably take a week or so.
