A weekend BASE jumping accident in a Utah canyon killed two people, one of them a daredevil athlete best known for performing onstage with Madonna at the 2012 Super Bowl, authorities said.

The sheriff’s office in Grand County, Utah, confirmed one of the dead was Andy Lewis, an extreme athlete known for feats in BASE jumping, a dangerous sport that involves parachuting to the ground after jumping from a tall fixed object such as a building, a bridge or a desert cliff overlooking a deep canyon.
