This image (below) on digital billboards is being shown in the St. Louis metro area and across the country. Twenty-five years ago this month on June 1, 1996, park rangers found the bodies of Julianne “Julie” Williams and Laura “Lollie” Winans in the Shenandoah National Park in Virginia.
The FBI is making a national appeal for information because people from across the country visit Virginia to hike the parks and trails. Also, people who had lived near the national park may have moved over time.
