This is a really sad case and I have been thinking about it for quite a while.
I was thinking that the gunshot wound is odd. That's a strange place to shoot someone- in the neck. Why not shoot her in the head? In fact, why shoot her at all? The killer was obviously strong to cut her up like that with a fine serrated blade (likely a hacksaw). She was strangled first, and he knew he killed her that way. Why then shoot her in the neck afterward? That's pure risk: risk of someone hearing the shot, risk of someone finding the bullet. Since it was unnecessary and risky it's something he just wanted to do.
He definitely planned this murder. I just don't think a full term pregnant woman would be travelling with three suitcases of identical size. Those suitcases were obtained with their purpose already known. He cut off the handles and painted the zippers black- he prepared them beforehand.
He had a place where he felt completely safe too. It takes a while to cut up a body like that. I figure he was not worried about the length of time, the huge amounts of blood, or the gunshot sound. I bet he had access to a locked room/shed/basement to store hacksaws, tools, paint, and three big prepared suitcases. Was it a safe room in a crowded area? I don't think so. I think it was a remote setting, maybe farmland. There's the straw in the suitcase.
Here's a wierd thing: Why go to all the trouble to dismember the body and place it in suitcases? It's easier, less messy, and less dangerous to simply bag a body and put it in the trunk. He wasn't doing it to try to separate the body parts because he threw all three suitcases in the same place. He did that because he was afraid he might be seen putting her in the vehicle and he had to make sure that it looked like suitcases and not a body.
So he has a remote place somewhere with a room/shed yet is afraid of being seen putting something in the trunk. Why? Because he lives with someone else who might see him, someone other than Beth Doe. Someone who is used to the sound of a gun around the place because he is a hunter, which is why the police said he "knew what he was doing" when he dismembered her poor body. Someone who'd had a flowered chenille bedspread for a long time. A woman. I figure his only means of transportation was a pickup truck and he had to use suitcases to disguise the body when he went to dump it.
Beth Doe depended on her killer for food, clothing, and shelter. She was found so very soon after her death. Surely the police were looking out and asking around for a missing full term pregnant woman. Yet she was not reported missing. She wasn't reported missing because the killer was her family and didn't report it on purpose. Also poor Beth Doe would have been missed if she had a job or close neighbors. It is no coincidence that she was killed near full term. There was something about that pregnancy that put her killer in danger and yet he kept her around as long as he possibly could, until the baby was about to be born. The killer wasn't her husband because then there would be no stigma to the pregnancy.
She had gold fillings but missing teeth at a young age. This speaks of a good beginning but a financial hardship in the last several years of her life. She was around 20. I don't think the man was her natural father because- sorry to be graphic- she would have been pregnant sooner. I think her natural father left or died, leaving her mother much poorer. Her mother later took up with this other sadist who kept to himself and made sure his womenfolk kept to themselves. He got Beth Doe pregnant and became afraid his secret would be known. He blamed it on her, was furious with her, thought of her as a




and therefore the cutting off of the nose and ears. He told Beth's mother some story about taking her off somewhere else to live. Beth Doe's mother was weak, abused, and had no means to support herself so she accepted this.
That's my crazy theory anyway. The killer was her stepfather, a guy who lived in a rural area and kept him and his family to himself, a guy who was pretty strong and mean. He didn't like anybody and nobody liked him. There was a run down house (a remnant of the earlier, more financially stable times) with a locked shed on the premises. He didn't have much money and was driving an old vehicle, probably a pickup truck, when he disposed of her body. He didn't live all that far away from the disposal site. He liked to hunt and liked guns. He was probably in the military at some point because of the suitcase preparation.
I'm still thinking about how the newspaper and writing on Beth Doe's hand fits into all this.
