murder

why are ppl so obsessed with leaving no evidence at a crime scene when it's smarter to just leave the wrong evidence. wear too big shoes, wear different perfume, leave strands of the wrong colored hair. If you kill someone in a car, clean all the evidence off, then dirty it up to a reasonable amount, it just makes sense. I'm not a serial killer I just like true crime and am this !! close to going f it and writing a murder mystery, or a criminal minds episode we'll decide when we get there
