exactly. You always hear about serial abductors and how they finally get caught 10-15 bodies later and its never because they were a suspect in any of the people's deaths its because after so much success they have that one sloppy moment and someone sees em. Or their house gets too hot (pun intended) with the bodies and someone smells something, or their dumping grounds gets discovered.
I mean what are the authorities to do if no one saw you get murdered/abducted and there was nothing connecting you to the perp?
I mean, just look at the BTK killer as an example.
Killed a bunch of people in the 70s and 80s, went on hiatus living a regular life, and would have never been caught if he didn't start writing and taunting the media again in 2004. Caught by his own stupidity.
