Campus Killings

America was stung by a string of highly publicized shooting incidents in the last decade, but violence in places of learning is nothing new, nor is it strictly an American phenomenon. Recent tragedies include a German teenager who shot and killed 15 people in March 2009 (at right, mourners attend a ceremony for the victims). The earliest school massacre may have occurred in 1764, when Lenape warriors burst into a one-room schoolhouse in what is now Franklin County, Pa., shooting the schoolmaster and scalping nine or 10 of his pupils. The deadliest campus attack in U.S. history was at Virginia Tech in April 2007, when a gunman killed 32 and wounded many others. Here's a closer look at some of the bloodiest school shootings on record.
