The email that arrived at Virginia Tech's health center in November 2007 was detailed and unmistakably ominous. It concerned a Tech senior named Daniel Kim and came from an acquaintance at another college.
"Daniel has been acting very suicidal recently, purchasing a $200 pistol, and claiming he'll go through with it," the email read, adding details of a reported previous suicide attempt with pills. "This is not a joke."
By the time Virginia Tech told Daniel's father, William Kim, about that email, it was too late.
A few weeks after it was sent to the school, he spoke with his son for the last time, Daniel indicating all was well and after final exams he'd be home for the holidays.
