Not sure what to do

One thing..........If you were to ask the company's creditors if you can have the copper, they'd say NO.

Second...............If your friend who gave it to you were to end up in court, he might be under oath to reveal that you received the copper.

Third.................Those who would like to take your copper will lie under oath, make you look like a thief and crook without any remorse.

My advice.........Keep your mouth shut, sit on it even if it takes years and wait out the pending / possible action /litigation that will arise. When the coast is clear, walk with it. Don't expect the "law" to act in your favor, as we have nothing more than a "legal system".....not a justice system. Been there.
