Caleb Moore, freestyle snowmobiler, died Thursday after complications arose from injuries sustained during his appearance at the Winter X Games in Aspen, Colo. He was 25.

On Jan. 24, Moore was attempting a backflip maneuver in his freestyle event when his snowmobile's skis rammed the landing, launching him forward and causing the snowmobile to roll over him as he lay face down in the snow. After lying prostrate for a substantial period of time, he was aided in walking off of the course.

Once Moore was examined at the hospital, it was determined that in addition to having a concussion, he had developed bleeding around his heart. He was then flown to St. Mary's Hospital in Grand Junction, Colo., for surgery. Following the surgery, his family released a statement indicating that Moore had suffered further complications involving his brain.

Prior to becoming a freestyle snowmobiler, Moore, a native of Krum, Tex., had competed as an all-terrain vehicle racer. He competed in his first Winter X Games in 2010 after only a month of practice, taking home the bronze medal in freestyle and coming in sixth for best trick. He went on to win the bronze medal for Freestyle Snowmobiling in both the 2011 and 2012 Winter X Games as well.

Moore's brother, Colton Moore, is also a freestyle snowmobiler and captured the gold at the Winter X Games in 2012. He suffered a separated pelvis last week during the competition. Moore's death is the first that has resulted from injuries sustained during competition in the X Games.
