Translation of "ill-gotten" into Spanish

St. Clair could hardly go to the authorities since you were pilfering money from his own ill-gotten gains, but maybe this will refresh your memory.

Clair no podía ir a las autoridades porque usted le robaba de su dinero malhabido pero quizá esto refresque su memoria.

Don't have any hopes that you can hide your ill-gotten gains or your black market goods!

¡ Ni piensen que podrán ocultar sus beneficios mal obtenidos o sus mercancías del mercado negro!
