According to the witness who later identified Rudi as the bartender serving them, it was Rudi who approached and flirted with the inebriated woman, assaulted her, and tried to take her home.
The bartender tried to save her, but Rudi insisted that she was with him and they had made an appointment. In the end they couldn't do anything because they didn't know the truth. They just hoped that what Rudi said was the truth.
Rudi had to admit that sometimes the reality when he was drunk and the truth that was served in front of him was actually very different. He was the depraved man who approached the girl, even raped her.
In the end Rudi married Claudia one month later. The marriage was arranged very quickly as Claudia was already in her fifth month of pregnancy. Herman also paid for and took care of all the police matters to prevent the news from spreading.
