Stolen Horse in Portola Valley, CA area 7/22/13

A horse I had on consignment in the bay area was just stolen on 7/22/13. He is a black/bay tb gelding about 16h 12-15 yrs old. 2 hind socks. Goes by the name Vinny or Vincent. Lesson horse type. They buyer gave us a phony name/address. I have filed a report with the county sheriff’s department for horse theft and also check fraud as the check she wrote us was from a new account with no funds. Any help or information is greatly appreciated. The person who has him now is the same person who nearly starved him to death 6 months ago. I’m terrified that he is in her hands again. Please help! Thanks, Katie
