license plate recognition systems, investigators traced the car to the Herndons at a hotel in Illinois. Although the couple had swapped the vehicle's license plates, an Arkansas Razorbacks logo seen in surveillance footage was still affixed to the rear of the vehicle.

Willie and Taiya Herndon were taken into custody in Caseyville, Illinois, and are awaiting extradition to St. Louis County.

Authorities haven't yet released any details about a possible motive. The investigation is ongoing.
