A college student from Alameda, California died after suffering head injuries in a skiing accident in Colorado last week. Jacob Koltun, 22, was in Colorado studying English at the University of Colorado at Boulder, according to his mother. Koltun was skiing in an expert area of Peak 7 without a helmet when he suffered multiple skull fractures, said Summit County Coroner Regan Wood.
And four days later, Krzysztof Kostelic, 46, was visiting Breckenridge on a ski vacation from Rolling Meadows, Illinois, when he died after skiing into a tree on Northstar, an intermediate run between Peaks 7 and 8. Summit County Coroner Regan Wood said Kostelic was wearing a helmet and may have had a medical issue that led to the accident. She has ordered an autopsy to determine the cause of death.
