Shock is turning into mourning.. mourning turning to anger. Anger to confusion..

Campus security is being questioned today..

Some are saying it's the fault of the gun culture in America.. Virginia Tech President Charles Steger did say that the shooter was a student at Virginia Tech in his early 20s but will not as of this time release his name..

Federal agents say that the guns had seriel numbers that were filed off--important in tracing where the guns came from.. Eyewitness accounts say that the shooter had clips of bullets on his shirt.. physically, he was described as wearing a maroon hat and leather jacket.. One eyewitness told NBC news he looked like he knew what he was doing..

Anger mounting as America reels..
