BLACKSBURG, VA - A day after the nation remembered the deadly bombings in Boston, another somber anniversary is being marked today.

Back on April 16, 2007, Seung-Hui Cho killed 32 people on campus of Virginia Tech before taking his own life.

The shootings took place at two buildings on campus, a co-ed dormitory and the engineering science and mechanics building.

Caitlin Hammaren, 19, of Orange County, was among the students who lost their lives on that day.
