Oddly worded for a confession note, and extra-odd that there were duplicate copies. Unless they can tie him to the crime with physical evidence, or he can pass a polygraph while confessing he did it, I think they should be seriously investigating the possibility that somebody else did it and put him up to writing the confession notes, by threatening him and/or other close relatives of his with the same treatment.
Who writes a pair of identical confession notes and leaves them in the same place? And if what’s quoted in the article is the full text of the notes, it gives no hint of a reason for the murders, not even an irrational one. Just sounds suspiciously as if designed to point suspicion at him, and accomplish nothing else, and he hardly needed to leave a note to do that — he could just have turned himself in, or if he was originally planning to kill himself, he could have made a 911 call to get his confession recorded.
Other articles on this atrocity mention that there was physical evidence that he tried to kill himself and failed. The interview with the police didn’t mention that but I had to stop listening when they were describing the location of the bodies as I have kids right around that age.
He apparently had serious money stress and serious issues in his marriage and he was depressed, on meds and in therapy for it. None of that validates killing your whole family over anything. Since he’s still alive we will learn more but lets keep the conspiracies to a minimum till we actually do, ok?
