Someone was keeping track of a car linked to Wynonna Judd and her sister Ashley. Now, police in Franklin, Tenn. want to know who -- and why. A GPS device was found on the undercarriage of a vehicle brought to a muffler shop on Friday afternoon (Nov. 8).

WKRN-TV in Nashville reports that a teen brought the car to the shop and asked a mechanic to check for a GPS device. One was found, and police came and removed it. There is an active investigation into the matter, but at this point there remain far more questions than answers, and nobody is talking.

Wynonna Judd has two teenage children (Grace and Elijah), and her husband Cactus Moser has three older children from a previous marriage, the youngest being 19 or 20 years old. Ashley Judd does not have any children.
