So I did a little of my own research. I saw on this site in earlier posts, that the cameras at guard gate went out on Monday, April 28th. So the murder was theorized to happen on Friday, May 2nd, or Saturday May 3. I searched it and I see there was some bad weather in the South that weekend, I'm not sure how the weather was specifically over there.
I looked on Zillow, and I see the house to the left, closer to the lake, and to the left of the REM lot, was on sale starting around like January 2014. It was for sale for a while after the murder too. With Coldwell banker. Which was the agency that Vicky Stephens was at. I don't know if she specifically was the agent there. I'm assuming that's the place, because people here have said that it was right close to the Dermond house. So the house for sale, was the next house over on the left, past a small lot. I would imagine, there would be a for sale sign in front of it. Maybe with her picture and number on it.
Also someone here earlier wrote that they thought Vicky Stephens had a seizure that day. I don't know if she has a known history of that, or what. I did read here that the drowning took place during the day too.
So this is my further thinking. My further theories. The perp went by boat to the area, the first time, while he was on vacation there, maybe at the campground there across the lake, because he was curious to see the REM lot. He had heard the rumors about that lot for a while before and wanted to see what it looked like. He got out the boat and hung out at the REM lot for a little bit. He noticed the house ahead of the lot was for sale and he saw the sign there. And maybe I'm thinking, that Vicki Stephens was on there with a pic and her phone number. And if she lived in the area for a long time, and also was a homeowner, she probably had her home address listed, so he was able to Google her name and her address. It's not a very big town there. It's possible he saw her there and her car there too at listed house, while he was there. And he started fantasizing about her, first.
So at some point he figured out about the parking pass, he copied somebody's sticker there by using his phone. So he made several trips to that house over time. Whenever he passed in the area. And at some point, the Dermonds saw him hanging around there. Maybe even Russell spoke to him at one point and asked him who he was.
So then he figured, if he wanted to get Stephens, he needed to kill Russell and Shirley first. Because they were eyewitnesses that he was there. He didn't mind, he figured that as part of the fun. So he attempted to do that first, to make sure that that went okay, and got the witnesses eliminated. When there was a big storm that went by in April, he took that as an opportunity to disable the cameras there at guard gate, to get in there more easily. He was already well aware of using weather events to cover up messing with cameras and houses. He made a few trips of surveillance that week there, getting in by car, in preparation. He also noticed the guard routine and when they went on break.
So he killed the Dermonds, and everything went well there, from his perspective. And after he killed the Dermonds, now he had to kill Stephens too, because maybe she saw him over there near their house too, and she was also a witness.
So then a couple days later, he went to kill Stephens at her house. There's no telling when he got there, I don't know her schedule that day. So it would depend on what she was doing that day. But let's say nobody saw her that day. I mean her real estate license just expired, so she probably wasn't really out working that day. So she could have been at home. Then that might leave an opening for this theory. If that is the case, it's possible he was in her house all day. Or maybe he even broke in the night before. Again I don't know the circumstances, or if she had any partner in the house with her. But the obituary did not mention a partner. So she could have been alone. So in that case, the perp could have been in there for a while. And he was probably trying to spend more time there. But then she got a text that someone was coming over, he answered back or he made her answer back, so he had to quickly drown her and leave. He didn't want to get involved in a big messy murder scene this time, because he figured that might be too risky. So he made it kind of ambiguous that time.
Either way, he was satisfied with his work. The only thing he was frustrated with, was that since these murders took place inside a house, he could not get near to the scene enough, to watch police process the scene. So he got the idea that next time, he might kill someone in a public place, so he can get better access to the crime scene.
So there you go. I think that theory could work.
