This undated photograph provided by the Pennsylvania State Police shows Charles Carl Roberts IV, who police say burst into an Amish schoolhouse in rural Pennsylvania 02 October 2006 and killed at least three girls "execution style" after lining them up in a classroom before taking his own life. Amish families gathered in shock outside the one-room building after the third fatal killing in a US school in the past week -- this time in the midst of a community which eschews violence and many of the trappings of modern life.
