A ‘free-flying’ extreme sports diving instructor has been jailed for four years after a woman fell to her death in a 100m plunge in front of her husband. “My wife was crushed before my eyes,” said Alexander Tkachenko. Yevgenia Leontyeva, 33, was reluctant to jump from a hotel roof even though she had done it before. The mother-of-three let her friend go first and that “free-rope” jump was successful, a court in Karaganda, Kazakhstan, was told. Witnesses said Yevgenia had appeared “frightened” – but heard trainer Alexander Muznikas, 33, urging her to jump. He told her: “It’s not the first time you’ve jumped. “You know how to do it. Did I put a seat belt on you for nothing?’ She is then seen in a terrifying video jumping from the roof, moments after her husband, Alexander Tkachenko, told her: “I love you”.

A support rope was not properly attached to a tree, according to reports. Screams were heard from onlookers on the roof and onlookers below were seen rushing to help her after the terrifying fall. A cross line to which her rope was attached – and which supposedly broke her fall leaving her dangling above the ground – either failed to hold or wasn’t even secured. A man can be seen falling to the ground as he falls down, reports said. It is believed she was holding the safety rope that should have been attached to the tree and was crushed by the force of her fall pulling on the unsecured rope. The bereaved husband said: “I have come to support my wife. “Well, how can you not support your beloved…. “My wife was crushed before my eyes. I was in shock and panic. It was clearly the employee’s fault. “They did not coordinate their actions. The instructor didn’t look down to make sure the rope was tied. He simply told her: “Jump!” “I don’t wish this on anyone. He is guilty. He should serve a prison sentence. This, of course, will not bring back my wife and the mother of my children…”.

Before the tragic jump, Yevgenia and her friend had posted ‘Live it up’ and ‘We’re going to fly’. He suffered a severe skull fracture and brain injuries, as well as multiple fractures to his right side. She was rushed to hospital but died as surgeons tried to save her. Friend Anton Shevelev told the court he had asked the trainer to remove the leash because Yevgenia was “scared to jump” and they were going home. But Muznikas convinced her to take the leap, she said. The woman had three boys under the age of 14, two of her own and the son of a relative who had died.
