So I am currently working a book, about a serial killer who goes by Black and recently committed his first murder where he skinned the legs and arms then gutted the guys abdomen after reaching his heart ripping it out and placing it on his shoulder above him. Since Black was wearing gloves there wasn’t any finger prints but my question is would the skinned parts of the body decompose faster and be a slightly more discoloured than the abdomen?

Then he goes into his job, a CSI (Crime Scene Investigator) but he gets called to his own crime and now is trying to lead the cops towards someone else or make it a cold case.

Also to add it goes into quite a bit more detail than just what I added but yk.
