In all, 33 people died Monday at Virginia Tech, including the gunman. The 15 who were wounded were treated for gunshots or other injuries, authorities said. Their conditions were not reported.
Campus Police Chief Wendell Flinchum would not officially confirm that the two incidents were related, pending the results of the investigation, but he referred to only one gunman and said no other suspect was being sought. Numerous federal and local law enforcement officials told NBC News that the events were the work of a lone gunman.
