Luke Adam Sanburg, 13, vanished on June 24, 2005, while camping with his Boy Scout troop in Yellowstone National Park, about six miles north of Gardiner, Montana. He and other boys were playing by the Yellowstone River, pushing logs into the fast-moving water when Luke fell in and was swept away.

An extensive search, including a three-day investigation of the river and its surroundings, recovered only Luke’s sneakers five miles downstream. Authorities believe he likely drowned in the unswimmable, 50-degree water; his body has never been recovered and he is presumed to have died. Luke had just finished seventh grade and was remembered as a bright student who loved math, poetry and music; he had two younger siblings.

Foul play is not suspected and the disappearance is classified as a tragic accident caused by dangerous river conditions. Does anyone who was in the troop or camping in that area that day have information that could add detail to what happened?
