The Prees family were on the last ski run of the day in Innsbruck when Jemima careered into woodland and was knocked unconscious. Her father and her brother Barnaby both witnessed the accident on February 10.
Recalling the incident, Tim Prees described how Barnaby spent 40 minutes trying to revive his sister, despite the fact she was "fairly clearly dead". His actions drew praise from emergency services who arrived at the scene.
They allowed him to carry on, because they did say they couldn't have done any better.
