If you killed somebody, how would you dispose of the body without getting caught?
No, no, I’m not advocating that you go out and try this — I’ve found that the police tend to frown on “but I was just doing research” as an excuse for this kind of thing — but if you write horror, or mysteries, this question might well have crossed your mind on occasion. There are some incredibly detailed, well-thought-out answers in this Ask Metafilter thread:
“First, be smart from the very beginning. Pulverize all teeth, burn off fingerprints, and disfigure the face. Forcing a DNA test to establish identity (if it ever comes to that) might introduce the legal/forensic hurdle that saves your ass down the line. An unidentifiable body can, in a pinch, be dressed in thrift store clothes and dropped in a bad part of town where the police are less likely to question it. I don’t reommend that disposal method, I’m just saying an easily identifiable body is an even bigger threat than the opposite.
Assuming you have it inside a house where you can work on it a bit, the first thing you want to do is drain it of fluids [….]”
