DeKALB – Jacqueline Do stared at doors for the longest time.

She could only wonder if random violence would walk through the doors of her lecture halls during her freshman year at Northern Illinois University in 2008. She expected stress and changes during her first year of college, but not the kind that comes in the aftermath of a gunman opening fire in a campus building and killing five students.

But as the weeks passed from that tragic Feb. 14, 2008, Do stopped staring at doors and started opening them for a brighter future.
