Or he and his wife are still making Sexy Time.
I think a murder-suicide is more likely. Borys away from the internet for 2 full days? I don't buy it. I bet he socked his wife in the jaw, ripped off the wedding dress, stomped it, placed her stunned and naked body on top of the dress, and just stomped repeatedly on her gash until he saw some shade of every color of the rainbow come out. After that, the hedge clippers came out, and maybe he had sex with her. He popped off each finger individually, and when he felt especially spirited, maybe he takes off a fingernail before the severing. After a hand or two, he realizes that blood loss might bring an unintended end to the sweet miseryhe is delivering, so maybe he uses a belt or part of the wedding dress to stop the bleeding. Needing to take a break for a bit from anything that will externally bleed, he starts work on the ribs. He hears knocking on the door and a voice asking what's going on, interrupting Borys's mental train of thought, which is pondering turning her intestines into exquisite polish meats.
