I doubt they will because they are overseas and rarely do foreign governments go through the serious effort required. Part of the reason why they have money deposited in other's accounts are because this way it is harder to trace the ultimate bank account the money ends up in.
I'm still amazed people fall for scams like this at all let alone to give away everything you own to a scammer. In this instance she knew she was being scammed and continued to sell her house and give up everything she owns- an intelligent person would have contacted the authorities to try to set up a sting or something not just willingly give up the rest of your money.
Even odder is to say she fell in love with the scammer given very limited contact. She said she was not in love with her husband of 45 years but fell for him quickly after a few talks. The whole thing is so bizarre.
But another show about being scammed online had the same thing- women falling in love with a guy they never met and it turned out the guy was a lesbian who swiped some guy's photo and was posing as a man. She didn't steal money just their hearts. I don't know what the hell is wrong with people...

After 42 years of being married although she claimed it was loveless, I suspect she did have feelings for him and found it difficult to come to terms with the loss. 3 years later she must have found life very lonely and decided to look at dating again and being vulnerable she accepted the most outrageous scam ever of love over the internet and telephone.
I believe everything is traceable to an extent. I am trying to think of the name of a celebrity here in the UK who's family were repeatedly threatened over the net.
To cut a long story short. The IP address could not be traced, it had several proxy's and hosts. But, the celebrity would not give in and found expert after expert to try and track down this mad person who was making threats to his wife and children. The IP address came up as being from across the other side of the world using a host in Europe. The IPA was going round in a circle changing the IPA every time it hit a host making it impossible to find the original source. So what they did, instead of tracking the IPA they went for the host and by doing that they tracked down the original IPA right to his front door and arrested him and charged him. If I remember his name I will be able to find the documentary and post it, it was very interesting in the way the abuser was traced.
