IIRC both the Chernykh sisters seem to have been Russians doing the marriage-immigration thing.
Maria was living with a different Mexican fellow (named Romero), presumably not a Muslim, and had a baby by him while allegedly married to US citizen Marquez.
I suspect her sister Tatiana was in the same arrangement with the older brother of Farouk.
Marquez was just a Mexican-American flake and patsy that fell in with that lot.
Are you suggesting that he New York Daily News article that says Marquez converted to Islam is not accurate? You say “he just fell in with that lot.” Falling in AND converting is more than just falling in.
This later report also claims he was indoctrinated into Islam, more than an Hispanic “flake.” One could call lots of these people “flakes.”
