Classes resume at university

BLACKSBURG, Va. (AP) -- Her back still aching from jumping from a second-floor classroom window to avoid being shot, Caroline Merrey knelt before a memorial to Professor Liviu Librescu -- the teacher who barred the door with his own body and helped make her escape possible.
In a way, Merrey was glad for the pain. It's another reminder that she's alive.
"Every time I bend and feel my back sore, I kind of go back to that room and I can picture what happened," the 22-year-old senior from Baltimore said Monday. "His selflessness is the reason I'm here."
Merrey joined several thousand other students gathered on the main campus lawn of Virginia Tech to remember the victims of last week's massacre. A soul-rending silence fell over the grassy oblong at 9:45 a.m., the moment the first 911 call came in from Norris Hall that a gunman was on the loose. People flinched as an occasional balloon popped, sounding eerily like the muffled report of a gunshot.
Then came the tolling of an antique brass bell installed on a limestone rostrum at the edge closest to Norris, where Seung-Hui Cho killed 30 students and professors -- and himself.
There were 33 peals in all. After each toll, a white balloon was released for each of the victims.
Finally, students and staff released 1,000 balloons in Hokie maroon and orange. As many as 90 percent of the students returned to campus, and school officials said class attendance hovered around 75 percent Monday.
At 7:15 a.m., a moment of silence was observed about a half-mile away near West Ambler Johnston Hall, the dormitory where Cho shot his first victims, Ryan Clark and Emily Hilscher. In front of the dorm, a small marching band from Alabama played.
