About the bathroom window, this is an emergency escape route, carefully prepared and thought out. The window is open, the screen is down, the shower curtain is open. If someone opens the front door, the same police, then he will run away through this window. A wonderful place to get away if anything. Through the window in the living room you can see what’s in front of the house, you can also see it from the nursery, and you can also hear it. The police can be seen, the neighbors can be seen and heard. But obviously I didn't have to use it. It turns out that he is very advanced in this regard, and he had to climb into houses before, and more than once. In fact, he got in without a trace, disappeared without a trace - and no one can understand how he did it. He searched well too, bank cards, savings books, looked for passwords (PIN), like a pro. But the murders - in general, like the first time, complete improvisation, a bunch of wrong actions, decisions. Starting from the choice of knife and the way to carry it. He wanted to rob quietly, he improved his skills, but something went wrong. He realized this when he got hurt and was covered in blood. He could have taken off his jacket and left it in the nursery, and then put on a clean one, but for some reason he didn't do it, didn't have time? When he took off his gloves in the kitchen changing the knife, he realized that he had already left a mark so it was impossible to hide the traces, a lot of his blood everywhere, fingerprints. That's why he was so angry at the end. Ice cream and cold tea - he tried to cool down. And he's not afraid of blood, and calmly walks around bodies. So he had encountered this before, maybe he killed animals. If his work is connected with something like that, for example, cutting fish, animals, then the injury is easy to explain - like he cut himself at work, it happens, and those around him will believe in a light one.
