According to the docket, some type of sale did take place in 2016. I'm guessing real estate, but since it doesn't specify, I could be wrong.
Perhaps the money used to pay creditors came from that.
The final report shows receipt of 4,756,437.20. That's a far cry from 28 million in pre petition assets.
Perhaps it's too soon to write this off completely, there may be a small glimmer of hope here.
