The National Park Service has confirmed that a body found in a creek in the Grand Canyon National Park is that of Jackson Standefer.
The 14-year-old McCallie student had been missing since he was swept away along with his grandmother, Lou Ann Merrell, while crossing a swiftly-flowing creek.
The body of Ms. Merrell has not yet been found.
The youth's body was taken to a local medical examiner for identification.
