Helper - Kristin Kimber Tiller, whose ex-husband, Brandon, was one of the three killed rescuers in the Crandall Canyon Mine rescue attempt, leads the release of more than 2,000 balloons at the Helper Arts and Music Festival Friday, August 15 2008, the eve of the one-year anniversary of an implosion that killed three rescuers and injured six others trying to reach six miners trapped by the catastrophic collapse of the mine's walls on Aug. 6. "The balloons symbolize a moment of release and letting go," said Kimber Tiller.
