This is:

XX wildly shouted that it was her, honest money, and that she was about to prove that she had earned them. "Prove it" said the investigator

The principle of the presumption of innocence is that the accused does not prove his innocence - it is the investigator must prove that the money is unfair. And if she claims that someone gave her that money, it doesn’t really matter if someone likes to go to the investigator or not. To find out and find evidence is an investigation. There is no evidence that the accused is a priori innocent. And yes, "sugging" is not a crime.
This is never funny.
