I have never understood the son-in-law's reaction to what he says was a phone call from the mother saying they were being attacked by three men.
As I understood, they did not live close by and there was a blizzard. Why didn't he call the police and say he had received this phone call, could they please check.
Instead, he and his wife get ready, they get a neighbor who's a private detective and drive over. I believe it took them awhile to get there.
If you received a phone call like that, wouldn't you first try to call back and if there is no answer, call the police and then go over there?
If the police still have the evidence (especially the ropes) I would think those would be a great item to have tested for touch DNA.
I wonder how many people in their 70's and 80's are sitting around worried about that murder they committed 40 or 50 years ago and have always thought they got away with it. And they're probably going to be caught because of little test one of their own relatives sends in to a DNA service.
There is another board on here about cases that haunt you, I posted several years ago and at that time Arlis Perry was my top case. Her murder was solved in 2018, so even the smaller single murder cases are being solved with all the new DNA evidence.
