Advice After Robbery

We had someone who had access enter our home (a domestic worker) steal hundreds of thousands of dirhams cash from us. The police found the culprit within a few days and have recovered 40% of the money. The public prosecutor advised us to open a civil case to reclaim the rest. This is very disappointing for us. We're not sure which any attempts if any would have been made to see if she remitted the money, or if she would have been pressured to give more back.

Is there even any point in opening a civil case? I don't see how anyone can force that person to repay it if they say they don't have the means, and as I understand the upfront court fees and any solicitor fees would be significant. My guess is that person may have managed to get the money back to their own country where they will surely enjoy it after deportation and there's little we can do about it.

Should we just accept the 60% loss rather than throw good money after bad?
