WASHINGTON (CNN) -- Caleb Moore, extreme athlete and competitor of the 2013 Winter X-Games has died.
The freestyle snowmobiler, attempting a backflip last week at the Winter X Games in Aspen, Colorado, couldn't rotate his machine enough to land the maneuver. The skis dug into the lip of the slope, bringing the 450-pound snowmobile crashing down on him. The vehicle slammed into Moore's head and chest. After initially diagnosing Moore, 25, with a concussion after Thursday's accident, doctors soon discovered bleeding around his heart. He had emergency surgery at St. Mary's Hospital in Grand Junction on Friday, a day after the accident. He had brain complications, and his family issued a statement saying he was in critical condition and being closely monitored.
On Thursday, a week after the accident, Moore died.
