Who are Hess people, why are they experts on these killers, and where do they get their information. In regards to the hi Holmes episode and his ( holmes') insurance fraud using cadavers it was said " there were cadavers everywhere ", which I believe is incorrect. During this time there weren't enough cadavers for medical schools so people resorted to grave robbing. Just seems like subjective material. Interesting subject matter but doesn't seem to be well sourced information.
