DEKALB, Ill. (CBS) -- On this day four years ago, a gunman opened fire on a geology class at Cole Hall at Northern Illinois University, leaving five people dead before turning the gun on himself.
A memorial service for the victims of the 2008 NIU massacre will be held at 3 p.m. Tuesday.
Meanwhile, Cole Hall has reopened after being shuttered ever since the shooting. It has been converted into an anthropology museum, and also features new high-tech classrooms and a computer lab.
The building went through a $6 million renovation.
