 An investigation is underway after a missing Idaho woman, Laura Lane, was found dead in her car underwater at the Buffalo Fork River in Grand Teton National Park. Wyoming Highway Patrol believes she drifted across the lane of US 26, off the shoulder, and vaulted off a cliff into the river. The car floated downstream for about a quarter of a mile, then submerged. Lane was driving home to Nampa on June 2nd.
