Caribbean Airlines / articles stolen from luggage

This incident happened on December 22, 2010. I placed a pair of brand new Nike Shox in my suitcase at - yes at - JFK airport immediately before checking into Caribbean Airlines. I travelled business class so my bags were handled by the airline from the time I checked in to the time they rolled off - a direct flight - in Grenada. When I opened my suitcase, the sneakers were no longer there. The only opportunity to remove the sneakers from the case was between the time I checked in and the time the case rolled off - first off the plane in Grenada (and there really was no opportunity to open the case in Grenada).
