The most recent school shooting in Germany occurred in 2009, at Winnenden in southwestern Germany, where 17-year-old Tim Kretschmer, went on a shooting spree at his former high school.
Kretschmer took a pistol from his parents and used this to kill nine pupils aged 14 to 16 at the Albertville Realschule, as well as three more people in a further rampage in Winnenden and nearby Wendlingen.
Following the spate of shootings he shot himself dead.
