'That Was the Desk I Chose to Die Under'

David Maraniss reconstructs: The roommates crossed paths near the bathroom door at 5 in the morning. In the Monday darkness, another school week at Virginia Tech was about to begin. Karan Grewal had pulled an all-nighter to finish his accounting paper. His eyes were bleary as he saw Cho Seung Hui, in boxer shorts and T-shirt, moving around him to get into the bathroom. No words were exchanged, but that is how it always was with Cho, the silent stranger among six guys inside Suite 2121 of Harper Hall. Cho, or Seung as his suitemates called him, never looked you in the eye, rarely changed expression, would just walk right on by.
