Scientist Bruce Ivins—who committed suicide last week after learning he would be indicted in connection with the 2001 anthrax letter-attacks that killed five—was mentally disturbed and spent time in group therapy in the weeks leading up to his death. Now, the AP has learned, he was also obsessed with the Kappa Kappa Gamma sorority. In fact, this sorority-girl obsession might actually crack part of the case:

"...Multiple U.S. officials told The Associated Press that former Army scientist Bruce Ivins was long obsessed with the sorority Kappa Kappa Gamma, going back as far as his own college days at the University of Cincinnati... The bizarre link to the sorority may indirectly explain one of the biggest mysteries in the case: why the anthrax was mailed from Princeton, N.J., 195 miles from the Army biological weapons lab the anthrax is believed to have been smuggled out of."
