Have you Seen this Pony?

I am not sure if there is a correct forum to post this in...

I am looking for a Black (no white) German Riding Pony Gelding (gelded December 2007), approximately 13.1 7/8, named "Rocky" (registered Rubinstein's Rock and Roll). He is registered with USEF, USDF, and American Sport Pony.

Originally located in Wellington, FL. Then was in Davie, FL and Miami, FL. Now location is unknown. The pony is for sale, however I have a Lien on the pony, as the owner owes me a great deal of money. I put 4yrs of hard work into this pony bringing him from barely broke to schooling 3rd level dressage (as a stallion). He is now being promoted for sale as a pony hunter. He was assessed by Jennifer Beiling as well as other professionals in the Wellington area.

I have pictures that I can email. Pony may be located anywhere. Owner has ties to Boston, MA area as well as Southern New Hampshire, in addtion to here in South Florida. The owner is neglible and does not care properly for his animals. I am seeking all routes to find this pony.

Thank you.
