BOISE, Idaho — The Rexburg police department and FBI are asking Yellowstone National Park visitors to assist in an ongoing investigation of missing Idaho children, 17-year-old Tylee Ryan and 7-year-old Joshua "JJ" Vallow.
The investigation has determined Tylee was last seen in Yellowstone National Park on Sept. 8, 2019, with her mother, Lori Vallow, and her uncle, Alex Cox, according to the FBI. Authorities are seeking any photos or videos park visitors took on Sept. 8.
Authorities say that the group was traveling through the park in a silver 2017 Ford F-150 pickup truck with Arizona license plates. The license plate number is CPQUINT.
Law enforcement officials are searching for photos and videos that may have captured the vehicle, the occupants of the vehicle, or any other visitor photo where the group is present.
The FBI has also created a website for visitors and the public to upload photos and videos that may contain JJ and Tylee.
JJ was last seen Sept. 23 at school in Rexburg.
