A fourth person has died on Mount Everest, and further details about the deaths are slowly emerging. Subhash Paul of India was being assisted overnight Sunday by Sherpa guides during a descent when he died of altitude sickness, the AP reports. Dutch climber Eric Arnold passed away Friday of the same malady, while Australia's Maria Strydom succumbed to it on Saturday. A 25-year-old Sherpa was the first to die this climbing season: Phurba Sherpa fell to his death Thursday while trying to prep a route for climbers just 150 feet from the top, CNN reports.
