I think you confuse me saying Turkish with saying living in Turkey. But someone can be Turkish and live in another country, you do not have to live in Turkey to be Turkish. Out of the billions of people in the world, most people (in USA, in China, in India, etc) do not know someone in Turkey bc most people do not know anyone outside their home country (especially given the fact that most of the world lives on like a $1 a day, they have no reason nor the means to know someone from a foreign country). Let alone do they know someone well enough to ask to stay w them,
Point is I think it would be extremely unlikely Steven knew anyone in Turkey well enough to ask them to follow around his wife and kill her. Given that he is not Turkish and not a part of the Turkish - American community in NYC, and it appears he did not live in a Turkish neighborhood in NYC, and given we know he never traveled to Turkey on business or pleasure, he likely would only know someone from Turkey if he met them at work, at school or in the neighborhood. But given what he told the Times about having to rely on friends of friends of someone else to set him up, it seems like he knew no one in his circle with Turkish connections.
I am not sure if you are American but we have had a slew of cases where the husband gets on TV barely caring about the wife's murder and it always is found out that the husband did it. Steve is not acting like those people. That is not to say he didn't do it, but he sure would be a great actor if he did kill her, bc he seems pretty upset to me. I live in NYC so I have seen him on local news as well.
