The family of missing Alpinist, and Spokane native, Jess Roskelley is holding out hope that he is still alive, but on Friday his sister says they believe that he and two other climbers were killed in an avalanche. The 36-year-old climber was tackling a difficult route on Howse Peak in Canada's Banff National Park. He told his father he'd call Tuesday night, but that call never came in.
