There are many more serial killers living outside the prison walls than inside.

Outside of dumb luck, the number one way serial killers are caught is through the help of the public.

We assume people we know can't be serial killers.

Often, a serial killer has no felony record.

In reality, serial killers are of average intelligence.

While there are many wonderful police investigators out there doing some very fine work, the majority of the time it is not brains that catches serial killers.
