The Truth Behind the Pen Marks

They say the devil is in the details. Dr. Gerald Blumenthal believes there is more truth to that phrase than most could possibly ever know. Dr. Blumenthal spent nearly 40 years studying the handwriting of serial killers to discover the idiosyncrasies that tie them all together. According to The New Yorker, it is estimated that there are more than 2,000 serial killers living in the US alone. According to Blumenthal, the most heinous and committed serial killers commonly masquerade as regular people, mixing in among the crowd. They have regular jobs. Live in normal neighborhoods.
