Virginia Tech students were encouraged to attend class Monday, the five-year anniversary of the school's 2007 massacre in which 23-year-old Virginia Tech student Cho Seung-Hui killed 32 people, then himself.

In the years since the deadliest mass killing in contemporary American history, classes have been canceled, with this being the first year the normal schedule will resume with hopes of healing on the mind.

Two victims are confirmed dead at Virginia Tech and the campus is on lockdown after a gunman opened fire Thursday.

The suspect in the shooting has not been captured yet. He is described as a white man wearing grey sweats, a grey hat with a neon green brim,  a maroon hooded sweatshirt and a backpack, according to the university's website.

An authority, speaking on the condition of anonymity, told the AP that shots were fired reportedly after a traffic stop.
