The FBI has released new photos of missing children Tylee Ryan, 17, and Joshua "JJ" Vallow, 7, from a trip to Yellowstone National Park they took with their mother and uncle just before they disappeared.
JJ was last seen at his elementary school in Rexburg, Idaho, on Sept. 23, according to authorities.
The FBI is now asking anyone who was at the park on Sept. 8 to submit "photos and video that may assist in the investigation" into the siblings' disappearance. Agents also shared a photo of Cox's silver 2017 Ford F-150 pickup truck and its license plate, CPQUINT. The FBI has set up a special tips page for the case here.
The call for help comes as Lori travels to Idaho after being extradited from the Hawaii island of Kaua'i. She is being held on $5 million bail and faces two counts of felony desertion of a child, as well as misdemeanor charges of resisting and obstructing an officer, solicitation of a crime and contempt, according to the Madison County, Idaho, prosecutor's office.
Lori has denied all allegations of wrongdoing.
