Uh, you want to tell me the last time that happened? "A person raped a woman..." Sorry, but no.
Maybe it would be easy to guess or figure out that these women are deviants, but to repeat myself from above: that's not the point. A reporter is supposed to give an explanation for bizarre things that come up in his story--not to leave them unexplained and make the reader guess at what should have been included as an obvious fact.
This reporter or his editor deliberately contorted this article in ten different ways to avoid mention of these women's sexual deviancy, as if it were not the least bit relevant. It's like the 10,000 lb. gorilla in the room. Tell us why they are prima facie such weird people (especially "Dad") and let US decide if it's relevant to the fact that they are evil, cruel sadists who get a kick out of kicking 10-year old boys in the balls and making them eat dog feces.
