If there was a short sale go into the official records to obtain a copy of the deed and see who actually signed it and in what capacity. The transfer may not be valid if it was forged or fraudulent.
When you review the deed to see who signed it you will be able to see if it signed by another person under a power of attorney. You should also be able to see (in the top left corner of the first page) who prepared the deed. If it was signed under a power of attorney, that preparer should have recorded the poa also. If they did not, they should at least have a copy. It is likely that the preparer of the deed was a title company. Since they insured the deed they should be able to tell you what happened.
