Footage of the June 13 incident shows Novokuznetsk Olympic reserve school student Jamshedj, 16, take aim at his coach Andrei Kiselev with a handgun and pull the trigger. During a police interview Jamshedj told police he was only "joking" with his coach and didn't know the handgun was loaded.
Some reports state that he ran to the scene to assist his coach, but the full footage shows a different picture as he rapidly leaves the scene.
Jamshedj has since been charged with intentionally causing Mr Kiselev's death.
