The whereabouts of Cho, and his reason for the time gap between the two shootings have been answered post-mortem by Cho himself.
Between his first and second bursts of gunfire, the Virginia Tech gunman mailed a package to NBC News containing pictures of him brandishing weapons and video of him delivering a diatribe about getting even with rich people.
"This may be a very new, critical component of this investigation. We're in the process right now of attempting to analyze and evaluate its worth," said Col. Steve Flaherty, superintendent of Virginia State Police. He gave no details on the material, which NBC said it received in Wednesday morning's mail.
NBC said that a time stamp on the package indicated the material was mailed in the two-hour window between the first burst of gunfire in a high-rise dormitory and the second fusillade, at a classroom building. Thirty-three people died in the rampage, including the gunman, 23-year-old student Cho Seung-Hui, who committed suicide.
The package included a manifesto that "rants against rich people and warns that he wants to get even," according to a law enforcement official who spoke to The Associated Press on condition of anonymity because he was not authorized to speak about the case.
Hopefuly, the information gathered by NBC will help to profile and prevent future attacks. We know that Cho had a long history of mental illness, but so do millions of other Americans.
