IMO this was not random... It was someone that Sherill and Suzie knew...
1. If Sherill was the target why not grab her at 11 or midnight when she was alone? Anyone familiar would of know that Suzie was not home because her car was not there. It doesn't make sense to wait so late even if she was awake, had lights on etc. She was just a tiny thing.
2. I don't think their was ever a knock AT the door. Suzie was a teenager before cellphones, social media, etc etc. what did teens do back then? They would go to their friends or girlfriends or boyfriends bedroom window to get their attention, especially that late at night. If that person felt secure enough to knock on her window then I am sure it's happened before and Suzie would of let that person in the house. The evidence states that the girls removed their make-up and probably their jewelry so I'm sure Suzies bedroom light was on as well as the bathrooms and her cars in the driveway..bingo you know she's home and awake
something happened, an argument, they started to assault the girls, Sherill woke up and I think it was just downhill from their....
I am curious to know if the cops or forensics were ever able to tell if the light fixture on the porch was broken while it was still screwed in or if it looked like it was removed then dropped.....does anyone know?
