School gunman's parents shocked by son's 'hatred'

The family of a German teenager who killed 15 people in a shooting spree said the deaths left them agonising over how they failed to “notice his despair and hatred”.

Expressing their shock and sorrow, Tim Kretschmer’s parents and sister said they never imagined him capable of gunning down nine students and three teachers at his former high school then killing three bystanders before taking his own life.
