When did they last have roof repairs or replaced? Does the home have shingles? Termite inspection or treating? Who did their car maintenance? Did someone wash the windows for them? What about central air? Did they have it serviced?
Thought with each of these, I can't see the motive.
Had the Dermonds spoke of selling their place? Moving closer to kids, or maybe into a retirement facility? Had the children spoke to them about the Dermonds future, and what would happen if they could no longer live on their own? Did the Dermonds have insurance to pay if they needed a nursing home at some point? Who all came to see them for Easter?? Was there plans for the other children to come during Spring Break or this Summer? How often did they visit their kids, or the kids come visit them? I've no idea about grandkids ages, but were any graduating soon either from high school or college? If so, were the Dermonds planning to attend?
What do we really know about the Dermonds? Did they sell their assets to just family or to others as well? Other than playing bridge, what was Mrs. Dermond's others hobbies or likes? Mobility problems, was this from arthritis or some other condition? Did she take pain meds? Mr. Dermond, we know he use to play golf, and liked to go for walks. He had knee surgery, so did they cause any mobility problems for him? Was he taking pain meds? Were they content at this stage of their life? Did they enjoy the large home, or were they at a point of wanting to downsize? Did they have close friends nearby? Friends that the children would know their phone numbers? When was the last time the Dermonds spoke with their family?
I know we don't have answers to these questions, just brainstorming while I sit here thinking about the Dermonds, their family, and the loss they are experiencing this holiday weekend. The first holiday without their parents.
