I watched two shows today on serial killers (ie. BTK and the Greenriver killer) and it was amazing to see how they went about putting those cases together. It was interesting to note also how mistaken they were in their profiling, too. Granted, it was relatively new when the cases began...but the FBI had to learn as they went along and found that profiling a serial killer was never an exact science. They still are just educated guesses.
Look how long it took to name and to put both of those killers away. Two and three decades!
I don't know they are hiding anything in WI, but they obviously don't have much to go on to put two and two together. Very scary scenario.
