I would say that the fiancee was there could well mean something that he caught her doing or something she said to him caused her to claim rape 3+ years prior?
She is reporting an old rape claim. He is there when she talks to the cops? One has to guess he prompted her to repeat that story to the police.
Is the fiance Scuse Me? If so, he knew all about this.
Maybe she never turned in the report on this alleged 3 year old rape.
Maybe Scuse Me was jealous of the old bf so the stripper to be made up this story?
Maybe she just enjoys the attention she gets by accusing men in groups of 3 of rape?
