That, and I found it so weird that he didn’t put all three in an oil tank, while he was at it. I mean, he was already being a sicko, why not finish? I wonder if maybe he noticed someone on the property and had to just get out of there, fast? Because honestly those oil tanks were a super good hiding place. Had he been a better liar and took some additional precautions, this would have been a really tough case to solve.
The whole thing is very weird. How drastic his actions, and how fast his confession, and how sloppy the deed. It’s like he just totally and completely cracked up.
