Hello!
I am a victim as well. I lost over 2000 euros in two years to a woman from russia. I have found a way to locate the images of scammers, in case they are real.
Go to
http://www.procomb.com select image detection or fotosuche.
In case you have a front face photo of the scammer you can submit it there. They look for images with the same biometric profile. This service is usually used to find images or videos that were posted without consent on the internet. But it helped me with my problem as well. you can submit a search anonym. The images of the women who scammed me were on several modelwebsites. I am thinking about booking her for a photoshooting!!!!!
Now I am trying to find out if the model on the websites is the same I sent my money to!
I had to pay 69 euros for that, but it was worth it.
