this serial killers who choose random targets almost always get away. they usually get caught because they get extremely arrogant and sloppy or even start taunting the police leaving clues and notes etc. like btk did. also about 50% of murders go unsolved. it is a shockingly high number. media tries to make people think everything is c.s.i. science fiction where they get good dna samples from anything and the most blurry footage can be enhanced to count the number of pubic hairs on his asshole through his pants.
