GRAND CANYON NATIONAL PARK, Ariz. (AP) — Grand Canyon National Park officials on Friday identified a 29-year-old Michigan woman as the person found dead in frigid water after a flash flood swept through a commercial rafting group's overnight camp site along the Colorado River.

Park officials said Rebecca Copeland of Ann Arbor was found Thursday near the camp washed away Wednesday evening by a torrent of water that rushed through a slot canyon.

Officials said a different commercial rafting group found Copeland and that the group also found an uninjured second person who also had been reported missing. Five injured people were evacuated by air from the canyon.

A National Park Service spokesperson says the injured were "very seriously bludgeoned by debris."
