** FILE ** A Virginia Tech student stands by a cardboard "VT" that was part of a makeshift vigil placed on a drill field at Virginia Tech in this April 17, 2007 file photo, in Blacksburg, Va., to honor the victims of the shootings on the campus the previous day. Virginia Tech failed to properly care for a mentally troubled student gunman and waited too long to warn faculty and students after he killed his first two victims in a shooting spree that eventually claimed 31 more lives, including his own, a panel's report concluded. Had university officials not waited more than two hours to tell the campus about the initial shootings, lives could have been saved when Seung-Hui Cho later began his massacre inside a classroom building, according to the report, released Wednesday night Aug. 29, 2007.
