2008_08_coughlin.jpgA friend described Herbert Simpson, the 30-year-old man nabbed for trying to blackmail Giants coach Tom Coughlin as "slow" and that he was "surprised he could mastermind a plot." Simpson is painted in today's NY Post as an an "overweight, awkward homebody, who lives with his mother." He was arrested Thursday for sending letters to Coughlin pretending to be two women who were former co-workers of Simpson's and would "expose a fictional sexual encounter with Coughlin" if they did not receive $50,000. The two former female co-workers were able to identify the handwriting as that of Simpson, who they said had written threatening letters to others in the past. Simpson is out on bail and has been ordered to undergo a mental evaluation.
