A hiker on Hermit Island in the Potomac River died Sunday after he was pinned under a large boulder, emergency officials said.
Rian Avarham Khalder, 25, had been hiking with his 14-year-old brother along the Potomac on the island near the Angler Inn boat ramp when he began to climb an area of rocks.
Some of the rocks gave way, Khalder fell and a large boulder came down on him, police said.
Montgomery County emergency services mounted a "technical rescue," including swift water boat teams. The rescue was made even more difficult as a line of severe storms moved through the area, forcing rescuers to shelter in place and wait for the storms to pass.
