15 killed by teenage gunman

A 17-year–old high school graduate yesterday went back to his old school in Winnenden, Germany and, during morning class, opened fire in three classrooms. Nine female students and three female teachers were killed instantly. Three other men were killed as the teenage gunman fled the scene.
Police said there appeared to be no immediate motive of the killer, though they are suspicious of the proportion of females murdered. Ammunition was left at the school, suggesting more killings may have occurred had the police not responded so quickly.
