A sign placed by a student rests on the memorial for the 2007 shootings during a vigil on the campus of Virginia Tech after two shootings on the campus in Blacksburg, Va., Thursday, Dec. 8, 2011. A gunman killed a police officer and then apparently shot himself to death nearby in a baffling attack that shook up the campus nearly five years after it was the scene of the deadliest shooting rampage in modern U.S. history.
