لما كان قد أفلت باستمرار بجرائم القتل
‏التي ارتكبها على مدى خمسة عشر عاماً
dann hätte er kaum über 15 Jahre lang

matando gente sin ser descubierto.
jamás habría podido pasar 15 años
matando gente sin ser descubierto.
il n’aurait pas échappé à la police
pendant 15 ans.
non sarebbe riuscito ad uccidere gente
per quindici anni senza farsi scoprire.
ele nunca teria conseguido cometer crimes
por quinze anos sem ser pego.
