This the account from Russell Brice, the expedition leader. It was his climbers who saw Sharp on ascent and again on descent.

Russell Brice of New Zealand runs the respected guiding company Himalayan Experience (Himex). He has multiple 8,000m summits under his belt. His team was on the north side of Everest in 2006, and Sherpas from his outfit had attempted to aid Sharp late in his distress.

Brice returned to Everest the following year. During their expedition, Sherpas from his team cleared three bodies off the route: one at 8,300m, one at 8,600m and Sharp’s body at 8,500m. With as much dignity as is possible in the circumstances, they dragged Sharp’s body to the nearby cliff edge and pushed it over the side of the North Face. The reason for such removals is detailed at this Quora answer. The Sherpas also tried to remove the Green Boots corpse; however, it was under snow, and earlier efforts to move it had failed as it was frozen in place.
