Summary: CargoNet received notice of a trailer theft from Franklin Park, IL. The trailer was equipped with GPS and logs show it briefly traveled to Summit, IL where it may have changed tractors and then drove straight for Philadelphia, PA. The GPS tracking device was not disabled until after it had reached Philadelphia. As soon as the trailer was confirmed to be in NCIC, CargoNet contacted Philadelphia PD and gave them the location of the trailer. The trailer was promptly recovered.
