Winnenden remembers the victims of the shooting spree 15 years ago. On Monday at 9:33 a.m., all the church bells in the small town near Stuttgart will ring.

A former student broke into the Albertville secondary school and opened fire with his father's pistol. He killed eight female students, one male student and three female teachers during class. On his escape to Wendlingen, the 17-year-old shot three other people and himself. The names of those killed and their ages are read out at a memorial.
