Arizona authorities are investigating the circumstances surrounding the death last week of a 15-year-old Northern California girl who collapsed during a desert hike overseen by a youth motivation group. Michelle Sutton of Pleasanton had gone on the hike as a way to distance herself from alcohol and drug use, friends said. She died Wednesday after she grew dizzy and collapsed in a remote area north of the Grand Canyon while hiking with four other youths and two adult counselors.
