On April 16, 2007, police in Blacksburg, Virginia responded to the deadliest rampage by a single gunman in US history.
A student named Seung-Hui Cho opened fire in a dorm and a classroom, killing 32 students and faculty before turning the gun on himself.
Several others were injured, and some students survived by pretending to be dead.
The shootings put national attention on how schools warn students about emergencies, laws about purchasing guns and mental health care for students.
Cho had previously been declared mentally ill.
Several events will be held at the school Friday, in remembrance of the students and teachers who were killed, Including a 3.2 mile run, that will start on campus right by the Virginia Tech flag.
A candlelight vigil will also be held later in the afternoon on the drill-field.
All classes are cancelled for the day.
