I would think that LE has done a DNA comparison between the east coast rapist and the oxford row rapist (the one that is linked to Morgan's case). There seem to be some similarities between all of these cases....or at least that's my opinion.
The following gives some information on the ethnicity of the rape victim in 2005...
We both noticed marks around her neck, says Jenkins, who says the woman told them her assailant had choked her until she lost consciousness. She thought she was going to die, then all of a sudden, she came to, and he wasnt there, says Jenkins, mentioning the passerby who scared the attacker away perhaps in the nick of time.
Jenkins says her son returned with a man and a woman who comforted the victim, and the three communicated in what she believes was Urdu a language primarily spoken by Muslims in India and Pakistan. The young woman felt more comfortable speaking in her language, says Jenkins, who says she never saw the young woman again but heard she had moved in with family somewhere nearby.

Yes, the fact that the victim is foreign, and not 100% familiar with American English, may mean the perp in this case may not have been an African-American, but rather a person of African appearance from a foreign nation. We cannot exclude either possibility.
Plus, the fact that she might be an Pakistani or Indian immigrant may have something to do with why the perp chose her as the victim. Maybe they could do a racial test on his DNA to see his likely country of origin.
Also, the people who spoke to the victim assumed that she was speaking in Urdu, but maybe she was speaking some other language. Would be interesting to know if they were both from the same country.
Or, foreign, was the victim simply chosen randomly as she was walking through an area which any American woman would sense as too dangerous?
A foreigner perp might lack an understanding of DNA evidence, since esp. in poorer countries, law enforcement is not as well-established as here. That could explain the flaunting of the tee shirt.
Apparently, he did understand pings. So maybe he is a foreigner here to do some technical work like an H1B.
But the tee shirt also seems to make the crime personal somehow: the perp's flag of success at committing a vicious murder with total impunity? Maybe someone saw MH as a threat in some way?
