It is the deadliest college campus shooting in U.S history.

So far at least 33 people are dead and several others wounded after an unknown gunman opens fire at Virginia Tech.

As police try to figure out what happened the community is in shock

By all accounts, it was two shootings separated by two hours on two
ends of the Virginia Tech campus.

A lone gunman entered a dormitory and shot two people around seven Monday morning.

While police were investigating that shooting, there was a report around nine A.M., of a shooting rampage, inside a classroom on the other side of the campus.

"He shot our teacher, then we all got on the ground real quick, and he just started shooting around at different people," says witness Trey Perkins.

It was the classroom where most of the victims were shot dead and most of the victims were students.

When they heard gunshots, some students in adjoining classrooms, jumped from classroom windows, four floors up.

The gunman's identity has not been released yet nor have the names of the victims.

Police are not saying if the gunman was a student or what his motive was and we also do not know if he took his own life or was shot by police.

The Virginia Tech campus was put on lockdown for most of the day and while it has since been lifted, classes are cancelled through Tuesday.
