Trying to buy a ramp queen

Found a 182T on the ramp that has not been touched or flow for at least 15 years. Found the owner but cannot reach him (I am speculating he may mot be inclined to respond to calls emails as he may have lost the plane to the bank), performed a blue ribbon search with the FAA and found the last lien holder (BofA) with no lien release. At this point I am thinking the bank may own it and decided to abandon it.

Trying to get advice how/where to call to see of there is a chance to buy it from BofA. The place is so huge and almost impossible to reach anyone with any knowledge.

Any advice or guidance from someone that has done this before would be great.
