Jory Thomas heard cries for help coming from the Yellowstone River.

The 14-year-old was at a campsite with his family in Greycliff, Montana, when he looked up and saw that a small boat and paddleboard had capsized after striking a bridge.

Three people were swimming toward shore, but one man was drifting downstream clinging to a gray cooler.
