The small German village of Winnenden is in mourning today, in memory of the 15 young people shot dead at their school, ten days ago. Thousands of people, including Chancellor Angela Merkel and relatives of the dead, gathered for a special memorial service. Some 15 giant candles, each with the name of one of the victims, were lit in a deeply-emotional moment.The service at St Karl-Borromaeus Church was broadcast live by German television, with widescreens set up around the village. Albertville college where 17-year-old Tim Kretschmer launched his murderous campaign has become a shrine. Cornered by police marksmen, Kretschmer later killed himself.
