Why Was Walter Arrested?

There was a bit of history between Roberto and Walter. At one point he worked as a technician in Roberto’s company. But for some reasons which we find later, Roberto fired him. This is what drove him to become an alcoholic. Seeing the state of Maria, it was a common notion that the culprit must be her father, Walter. So when they reported the incident about Maria, the police arrested him.

Did He Assault Maria?

No, he did not. Even though he had a bad history, he never touched her daughter. We later find out this when Maria comes to her senses. Roberto came to find the real culprit and went on his way to perpetuate them.

Who Assaulted Her?

It was the duo of Dario and Curzio who were involved in the assault of Maria. Curzio, the owner of the villa was a huge germophobe. But of course, he has his sexual needs. To quench his thirst for sex, he used to watch Dario having sex with the girls and pleasure himself.

One day Dario brought Maria to the villa but she was unconscious. He just couldn’t have sex with an unconscious person so he refused. With his thirst for sex, Curzio took things into his own hands and sexually assaulted her. However, when he remembered his condition as a germophobe, he instead started beating Maria.

But still, Curzio had a respectable position in society. Nobody would believe Roberto’s words. To tie in Curzio with the assault, he created fabricated footage that involved Curzio assaulting Maria. The true face of Curzio gets out as he receives humiliation from the neighborhood.
