I have thought about this a lot. The Dermonds seemed quite social and active, especially for their age, I mean they moved into their current large home in their early or mid 70's while most people that age are downsizing, and president of the bridge club, and an avid walker, socializing at parties. Even so, they were in their late 80's so I would be very surprised if their neighbors and friends didn't get concerned when they didn't show for the party. I mean, if Mrs. Dermond had slipped and fell on some water in the bathroom or kitchen and then Mr. Dermond heard her cry out and he came running to help, then he fell, they both could have been lying there for days and died. But even moreso, I wonder if family members had tried to call. I even wondered if a family member called the neighbors when they didn't hear anything. I wonder how often the children and grandchildren talked to the Dermonds. Of course, they probably would have called security or even the police to do a welfare check if they were concerned.
Curious-Cat, I live in a self contained gated community in north GA, that is very similar to RP/GW but mountainous, and with many retirees. Seems that the 80s are the new 60s. Folks move here for privacy, fire/security, amenities/clubs, safety, and many other reasons. Folks respect other people's privacy. Remember the residents of RP/GW have never experienced a horrific crime like this before in their perceived virtually crime free community..
With that said, there has been many abductions that we have followed in the past where the perps either sent a text or forced the compliant victim to call a friend or next of kin, leave a message on their voice mail, etc., to establish an explanation for their absence.. The Megan Sharpton(07/2012-TN) abduction/rape/murder is just one example of where this ruse was used.
Although we have received more investigative info in this case than most. Sheriff Sills, may have decided to keep this as hold back info, close to the vest..
