Killer Nerds... HE: A scheming 17-year-old honor student and the twisted mastermind of an assassin-style computer program called 'Infierno' which he used in 1986 to slay his family in a bloodbath so heartless and gruesome it was dubbed "the crime of the century" in upstate New York. SHE: A gun-toting Harvard-educated professor with dark secrets, a hidden violent past, and a taste for blood so uncontrollable it would lead her to plot against and execute her colleagues in the Huntsville campus massacre of 2010. Two evil geniuses...both infamous mass murderers.
