I find it extremely striking and telling that DR displayed such ease and confidence, and perhaps most importantly, preference in selecting homes when he KNEW children would be home. In K. Ramsland's book, Confessions of a SK, DR explains that he knew from his stalking of Ms. Otero that she would be home with her children at that time. (Mr. Otero's presence surprised him.) He didn't strictly target Ms. Otero. He targeted Ms. Otero and her children! He felt at ease with children being present and specifically selected a time he expected her children to be home. I find it extremely difficult to believe that he would select children in a home -- a mom with children -- as his first offense. I think he displayed a confidence and ease in targeting children and multiple victims because of previous experience doing so.
I think we see the same striking selection of children in Ms. Vian's murder. He met her 6 year-old son on the street and watched to see which home he entered. He specifically selected a home where he knew children would be present, though in this instance, he did not murder Ms. Vian's young sons.
I'm left wondering if he gained experience with some sort of crimes involving children (or children being present) before the 1974 murder of the Otero family. I am inclined to think he had some prior experience in such to have such ease with children being present and indeed a preference (on at least these two instances) for children being present.
I am struck, too, that the horrific drawings of the young girls in the barn that have been recently publicized are, at least according to some respects, potentially identified as young women. But the drawings appear to me to be girls, not young women. If indeed the drawing of the girl in the green shirt has been correctly identified as the woman last seen in a green shirt-dress who worked as an exotic dancer, I would be interested in knowing if she ever (or typically) wore her hair in the two pony tails. I think the hair style is one seen on young girls. I also find it curious that if the drawing is of the missing young woman last seen in a green shirtdress that he has depicted her as much younger, more pre-pubescent or early pubescent, instead of her actual age.
Just some thoughts on some aspects that I find quizzical.
