Adam Lanza Was 'Much More Disturbed' Than Jeffrey Dahmer, Dr. Michael Stone Says (VIDEO)

Adam Lanza, who carried out the massacre in Newtown, was "much more disturbed" than infamous Wisconsin murderer Jeffrey Dahmer, Dr. Michael Stone told HuffPost Live on Tuesday.

Stone, a Columbia University professor known for his expertise as the "Doctor of Evil," said that Lanza was "totally unable to open his mouth and make communication of any sort toward the end of his life," just one of several factors suggesting greater disturbance in Lanza compared to the serial killer-cannibal Dahmer.
