No, that article just repeats what the other article said. The crappy local news probably just repeated what the cops said, and the cops are Texas cops, who, if Ms. Nash is any reflection, are not exactly the picture of sensitivity toward queer folk of any sort. The statement that the victim was a prostitute (whether it's true or false) probably means that she is a woman: far fewer men than women are prostitutes, and even fewer described are described as such.
Regardless of the victims gender, when Ms. Nash goes to prison, I'm afraid that my usual zeal for the Eighth Amendment won't stop me from being completely content if she is raped daily by prison gang leaders every day of the many years of her sentence.
