Four people have been critically injured after a lightning strike outside the White House, fire officials said on Thursday. The District of Columbia fire and emergency medical services department said the four people were injured in Lafayette Park, located directly outside the White House complex. They were all taken to local hospitals in critical condition. A portion of the park remained closed Thursday evening with emergency crews at the scene. While details of the strike remained limited, the Washington Post reported it was the result of a large thunderstorm that swept through the city in the evening, unleashing high winds and severe weather. In a separate incident on Thursday, a lightning strike in Wyoming’s Bridger-Teton national forest killed one student and injured another, officials said. John D Murphy, 22, of Boston, died of cardiac arrest after being hit by lightning while on a trip with a group from the National Outdoor Leadership School, a non-profit global wilderness school. Terry Watson, president of the school, called 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 in a statement.
