A lightning strike at an outdoors educator course in the Bridger-Teton National Forest in Wyoming killed one student and injured another, officials said on Thursday. 

The announcement came on the same day that a lightning strike killed two people and critically injured two others in Washington, D.C.

The group with the National Outdoor Leadership School was just days into their trip and had set up camp near Enos Lake, south of Yellowstone National Park, when a thunderstorm moved into the area Tuesday evening.

22 year old John D. Murphy of Boston died of cardiac arrest because of the lightning strike, Teton County Coroner Brent Blue said on Thursday. 

Blue did not know if the lightning struck Murphy directly or passed through something else to him.

The injured student was flown to an Idaho hospital for treatment and released Wednesday, Shana Tarter, the school's associate director for wilderness medicine, told the Jackson Hole News & Guide.

Nine other students, three instructors and two search and rescue members stayed the night in the back country after the lightning strike, school officials told BBC News reporters.

National Outdoor Leadership School President Terry Watson issued a statement, calling the lightning strike a "very sad day" for the school, its students and their families.

"We extend our deepest condolences to the family of our student who passed away on this course and are focused on supporting their family through its difficult process," she said.
