I have not read through all these. Seems to me that OP is more knowledgeable than myself about the technical part of this.
Some webpages which might be interesting to you.
Neal Rauhauser has one posting of a scammer who appears to be from overseas, but is local. They just use Overseas Servers as part of hiding.
If these guys took money from you. Then, I would guess, they are either not the government. Or if they were the government, they would have taken your money as cover for some other purpose. so what else do you know, or you are that they might be concerned with?
For myself. If the government ever heard of me. I am just obnoxious, I might want say I know something that I really know nothing about. I do not keep weapons. I do not live close to where important people are, or go near them. I do not make threats.
There was once a story of a Journalist, who found a geo-locator on his auto. This was years ago, before the easy to use Apple Pods and such. As a Journalist, he had gone to protests against Atomic Reactors, and the radioactive waste they produce.
On a scale of the government being evil. That is not much evil at all. They did not threaten him. Or harm him. Well, except one way.
He offered to give the device back to the FBI, they just had to say it was theirs. When they did not acknowledge it was theirs. He offered it for Sale on Ebay. Feds accused him of --selling -however they termed it, property of the US government. Then again. Might be the guy who wrote the story made it all up.
Unless your family is super rich like Elon Musk, Bill Gates, and who might refresh your bank accounts with huge sums of money. They are probably gone, as they do not want to be caught by some Cyber Crime division of the government who might be watching your accounts.
You did not say if you gave your complaint to -whoever the government has that investigates this type of Cyber Crime. (FBI, or ----)
If you really felt it could be the US government, you could file a FOIA request of any information that pertains to you. I would guess, https://www.eff.org/ could help with that. Of course, that might put you on their suspiciously weird person list. I probably would not file an FOIA.
I would also guess it is possible that those who got into your electronic devices, are not one person, but a team of hackers. They might be back after several months with a new pitch, crafted towards a person already burned.
I do recall a story about how Cell phones, can somehow have, indirectly have their cell services downgraded to earlier Networks, which had less protection against the cell phone having malware installed. Like forcing the 5G to 4G, then 3G, to 2G. Just long enough to install malware.
Only thing I can be sure of, “I am gullible.” just I am too poor for anyone to find it valuable to mess trying to empty my bank accounts. All risk, and no financial benefit to them.
I recall a quote about a Police Detective; He said, he “could be talking to a suspect. and the guy was so good, that he wanted to believe the suspect had done nothing wrong. While at the same moment he had a file in the next room with absolute proof that the guy was a crook. when he finally showed the file to suspect. The suspect would admit he had done it, and start working a new line. Like my grandma needed medical care.”
What I am saying, it is easy, even for those who are not gullible, like me, to be taken in with by a confidence man, scammer. Who would not find Robert Redford in, “The Sting” to be believable?
