I hate quoting my own post, but just still thinking on the bones and missing shoes. I was thinking it wasn't as unusual that there were missing feet because there are other missing bones-- but this actually is just as weird because there was no predation. At first, I was assuming well, there may have been predation at an earlier time. But just looked it up and they can tell based on all those bones recovered if there was predation.
Not liking to be so graphic, but is it possible that there was indeed predation to some extent and the bones were moved in part for that reason? And that's why there is not a complete skeleton? I have no idea if that is possible.
Or, and I'd hate to think this but what if he kept her in water secured to the bottom by her feet like in cement? He goes to move her but can't because her feet were weighing her down, so he moved the rest of her. It would look even more suspicious if she was found with her feet encased in something or attached to weights of some kind. Didn't Scott Peterson make his own weights with cement? We know barry liked to listen to true crime so perhaps he got an idea from that? There was a lot of talk about her being in water and then there is that bizarre story of barry being all wet when Suzanne's brother encountered him near the property one day while there was a search party looking for her. I guess they could tell if she was under water for any length of time though and I haven't read the autopsy report. I'm just offering a possible reason why the feet are missing.
I don't know if anyone is familiar with the Can/Am Missing Project? They investigate people who have gone missing in the wilderness. There are several stories of bodies being found with missing shoes and feet. Some of those are related to predation but I don't know if this is kind of a unique or unsloved phenomenon. I just recall several stories where this happened to people and they all happen with bodies that have been exposed to the elements over time.
For example there was a story of a missing hunter who was very capable of surviving in the wild. He had gone missing with several search parties coming up with nothing. Then one day someone found the hunters boots but not the body. It wasn't until a few years later where the body was found. They found him leaning up against a tree with his clothing on and everything, however his feet were missing!! He was many miles away from where his boots were found!!! No one could explain it and it just added to the mystery. Anyway that is not the only case I've heard of of people being found without their feet
