What information did Brando finally reveal when various methods were used to get him to talk?

Interestingly, it turns out that the information Brando had been withholding was useless anyway. He accepted a great deal of punishment in order to avoid telling the police chief and his men about the upstairs room in the Witch's house. The last bit of information Brando told them before they ceased torturing him was that he had returned to the Witch's house later that night after the Witch's body was already in the canal, and that he had tried, but failed to break into the locked door upstairs in the Witch's house before fleeing the scene a second time
