If the scumbag earl won't accept responsibility for what happened, even if they make the goons talk, then they can just sell those goons as slaves. There was a bunch of them, plus the wreck of the golem. Considering the goons were in a good shape to be able to pull off criminal activities, they would work hard in a mine, so finding a buyer wouldn't be too difficult. Of course the one knowing magic could be sold separately for an even higher price. Bina would be able to afford a very nice house with the money earned.
