Inside room of UCF student who plotted rampage

Campus police at the University of Central Florida released surveillance video taken from a helmet cam as they unlocked the door to James Seevakumaran’s room, finding the student dead from an apparently self-inflicted gunshot wound. Police say two packages had been mailed to Seevakumaran containing new ammunition clips, and he had made a timeline of what he planned to do. NBC’s Brian Williams reports.
