check craigslist, if you locate a vast majority of your tools in one location and let the local police/ sheriff know, they may be able to go forward and make an arrest even without identifying marks (example: pinging their cell phone to your shops location or fingerprints from the scene)
You will have to do the initial legwork, but hopefully the proper authorities can take over.
If all else fails, there are no traceable balistics from a buckshot blast, seriously
