The local police spent some time on the investigation, and finally recovered the laptop. Just a few days ago Jim picked it up. Many of his files were gone, but the Mac itself was in pretty good shape.
The investigators said the laptop had changed hands at least 5 times, and was probably used at least once as payment in a drug deal.
The perps may never be identified because of the laptop constantly changing hands, and no one seems to be talking. A happier ending would have been to have the crooks caught, but at least the laptop is back, and Back to My Mac helped accomplish the rescue. There have been other cases of Back To My Mac rescuing Macs and Apple's Find My iPhone service (also part of MobileMe) tracking stolen iPhones.
Thanks to Jim for sharing his story with us.
