Double-amputee climber Mark Inglis said in an interview with the press on 23 May 2006, that his climbing party, and many others, had passed Sharp, on 15 May, sheltering under a rock overhang below the summit, without attempting a rescue. Inglis said 40 people had passed by Sharp, but he might have been overlooked as climbers assumed Sharp was the corpse nicknamed Green Boots, but Inglis was not aware that Turkish climbers had tried to help Sharp despite being in the process of helping an injured woman down (a Turkish woman named Burçak Poçan). There has also been some discussion about Himex in the commentary on Inglis and Sharp. In regards to Inglis's initial comments, he later revised certain details because he had been interviewed while he was ...physically and mentally exhausted, and in a lot of pain. He had suffered severe frostbite - he later had five fingertips amputated. When they went through Sharp's possessions they found a receipt for US$7,490, believed to be the whole financial cost. Comparatively, most expeditions are between $35,000 to US$100,000 plus an additional $20,000 in other expenses that range from gear to bonuses. It was estimated on 14 May that Sharp summitted Mount Everest and began his descent down, but 15 May he was in trouble but being passed by climbers on their way up and down. On 15 May 2006 it is believed he was suffering from hypoxia and was about 1,000 feet from the summit on the North Side route.
