Good point! Maybe mh didn't leave fingerprints though, he may have been wearing gloves at some point and/or wiped off the beer cans, not thinking about saliva and DNA testing. Perhaps that is another reason why it took Friday and Saturday, while LE was processing evidence, to enter mh's house and rescue Sarah. I imagine mh learned a lot while he was in prison, why leave beer cans with traceable evidence if you don't want to be found? Either it's stupidity, forgetting about one critical detail because one is caught-in-the-moment, or maybe taunt LE?
How many beer cans were found? Does he have any history (from family/gf's) of any drug use? If he was ALTERED in any way, he wouldn't have been thinking about DNA. I think he is nuts, for lack of better term. Sociopathic, but low IQ. I do not think he is SMART, as evidenced by his prior theft/arson act. I am telling you, I think he acted on IMPULSE, then RAGED, and I think drugs/alcohol enhanced this. Perhaps he needed courage to carry out his plan, and that helped him. I do not think he was a simple, run of the mill (if there is one) pedophile. He ATTACKED that family... very different, and focused in on one member. He may have been stalking the whole family for reasons we cannot fathom.
I am sure, after the fact, he thought as quickly as possible, and wiped down areas, cleaned as well as he could. I just don't see him as a Hannibal Lecter type, with cunning, planning, intelligence. I see him as acting on some sick animal need after stalking his prey. That is my feeling on this. And I'm sure, he watched that house from his parents' house... he knew when and how long Tina's estranged (or then) bf left for his long shift, 80miles away. I do not think he knew personal details about the family, nor even cared- just their comings and goings. Just my observances.. I think he considered himself animal-like, from his behaviour of sitting in trees watching people, aloofness, collecting leaves and other matter, and habits toward animals. I would not be surprised if he thought of himself as a hunter type of animal. This guy could have become the next Dahmer/Bundy after this escapade... it is a miracle they caught him when they did. I don't thing Sarah would've survived much longer. I have such a bad feeling about him, I cannot even put it into words. I think every time a person like this commits murder, it gives them power and a warped sense of self-esteem. It drives them to commit the next one. If this was his first, the next would become easier and run more smoothly, so to speak. First time serial killers are SLOPPY. They are typically "lucky" not to get caught. This is no crime of passion, no schitzo gone paranoid... I think we are looking at a true sociopath, with possible delusions, self-medicating with drugs/alcohol.
I only pray that he gets capitol punishment, and is taken out of the human race so that other innocents can live in some level of peace. Rant over now!
