In this situation you should work with a lawyer to have law enforcement discover the owner of the tracker as part of the process to achieve a civil restraining order. It's probably also doable pro se. There isn't a clean path to obtaining that information merely by filing a police report or having a conversation with an officer. I would think officers would point you to civil court, but if they don't, it wouldn't take much to discover the process.
