I live in Europe, so these cues will probably never surface. I did get a lead 4-5 years ago where one of the cuecases and an the worst cue was posted for sale on a website. I got into contact with the seller who claimed that the cue had belonged to his tenant who'd left without paying rent, and they'd confiscated his stuff. That could have been a lie, but the guy seemed believable enough and not at all like a petty criminal. At the time it had gone too long for any prosecution to be made and the one cue and the case that did surface was all beaten up at this point. They did offer to give it back to me, but at that point I was over it and they were adament that they didn't have any of the other cues or tools/electronics. I believe the likely suspect of the crime passed away from an overdose. He was a sort of known figure locally, small time dealer and crook.
This was a major burglary where a number of tools were stolen from a workshop, and various electronics as well as my cues and other private stuff belonging to others from the office. I talked to the others at work when I got my lead, but nobody really wanted to take this any further since it had been years.
