Scammer lives in Ukraine, there are 2 victims, but the victims are in another country (I am in Russia), so it is unlikely that we will be able to reach the law enforcement agencies of his country. Moreover, given that there are tense relations between these countries.
Too bad because of the tension between Russia and Ukraine, we can't have cooperations for both countries and also we have a hard time pursuing cyber criminals even though the technology exist. By the way, I commend your scam accusation thread because it is thorough.
