Father driven to kill by grief: The true story of the husband who murdered air traffic controller he held responsible for crash that killed his wife and children that is behind new Arnie movie

Driven to murder by grief and a suffocating sense of injustice, a Russian father tracked down and slaughtered the air traffic controller he blamed for the mid-air crash that killed his family. Vitaly Kaloyev lost his wife and two children when a passenger jet and a cargo flight crashed above Germany in 2002 (main). He was adamant it was the fault of aviation expert Peter Nielsen, who was working alone when the tragedy occurred. Grieving Kaloyev (left and inset left) spent two years searching for answers and when he thought he had exhausted every option, he tracked down Nielsen and stabbed him to death in his back garden. The heartbreaking story is being played out in a new film called Aftermath (inset right) which stars Arnold Schwarzenegger as Kaloyev. Following the tragic crash, which claimed the lives of 71 people, Kaloyev spiraled into a pit of depression, refusing to shave and constantly wore black. He turned the family home in Vladikavkas into a shrine to his family - wife Svetlana (top right), 10-year-old son Konstantin (one from right, bottom) and four-year-old daughter Diana (one from right, top) - and set about seeking justice for their deaths, which resulted in him sneaking into the house of the man he held responsible and killing him.
