How do I locate an iPad that never had a fixed apple ID associated with it?

Question

If an iPad was lost or stolen and no fixed apple ID was set up for that device, and the device was reset to factory settings could that iPad still be found and would restting iPad delete the data plan off the device?
I ask this question because recently at my job it appears that the work iPad was lost and or stolen. It never had a fixed apple ID so we couldn't use iCloud to locate it. Managers just recycled through their personal apple ID's. it seems no one got a serial number for it, or the data number it used. My manager says they are tracking it through the data plan, and that she has something called high tech crimes involved in tracking it; but I thought if it was reset the iPad is pretty much lost since they failed to get all the info.
Is there a way to still track the iPad?
Ironically, I told Managment what to do to set the iPad up yet no one listened to me. They have the same issue with their current iPhone 4S. Guess some people will never learn lol

Report to police along with serial number. Change all your passwords.
