Skier's death attributed to heart condition

SANDPOINT - A 15-year-old skier who was found unresponsive in a tree well in Schweitzer Mountain Resort's north bowl last December likely died of an undetected heart condition.Coroner Kitt Rose listed William Clyde Johnson's cause of death as a "probable fatal cardiac arrhythmia" and the manner of death as "natural," according to a copy of her report obtained by The Daily Bee.

"It's just one of those bizarre things from left field that you have no idea he even had. It's nothing that the doctors missed; it's just that there was never any way to even suspect it," said Johnson's mother, Susan.Susan Johnson said an autopsy revealed that her son had an anomaly in his left descending coronary artery.

"My son was the picture of health - he ran cross country, skied, snowboarded and wakeboarded," Johnson said. "It came as a huge surprise. We don't have anything like that in the family."The Sandpoint High School student athlete was found unresponsive in a tree well, sparking suspicion that he suffocated after falling head-first into the dangerous void at the base of the tree.

Tree wells form around the bases of evergreen trees when low-hanging branches prevent snow from consolidating around the tree trunk, creating a hole that can entrap skiers and snowboard riders.Sheriff's officials said Johnson was discovered by snowboarders riding in the north bowl shortly after noon on Dec. 22, 2009.
