Oh - and the report said the victim was a white woman.
That's the cops' determination based on color of the skin. The genetic lab analysis concludes only that the samples belong to a female. DNA analysis cannot determine race. It would not stand up in court. That's why on these cop shows when they have the DNA of a killer but nothing else you don't hear them say, "Analysis of the DNA told us we were looking for a black man" or something like that. It doesn't work that way.
If you put the DNA of a white man and a black man side by side in petri dishes and examined each you'd find, for example, the gene responsible for blue eyes in both even if the black man had brown eyes. And you'd find the gene responsible for black hair in both samples even if the white man had blonde hair. The gene responsible for skin pigmentation is the same in both samples. We all carry the same genes. The human race is incredibly homogenous genetically speaking.
So while I suspect the woman in question is probably white, there exists the possibility that she is Asian or light-complexioned Mexican or something. That should not be ignored.
