How to spot a Satanic ritual murder victims body

so many unanswered questions:
1) why cover her with that creepy blanket
2) where her eyes closed to avoid the akward
3) why are there two styrofoam pillars in the back (why does the set in general look like cheap porn, even the music at the end has a 80s east european porn feel to it)
4) why so thorough throughout the video and then he just stops demonstrating
5) when and especially why did this man decide to become a satanic murder rituals expert
6). I love the by the way cluse at the end
