Ok. Got more good info today.
First, everyone who was scammed should go to the website https://www.ic3.gov and file a complaint. Starting there with as many people as possible all pointing the finger to the same guy in the same area will make a nice big wave of info that should pique the interest with those that review those complaints. I don't exactly know what that website requires to file a complaint, but a joint plan of action among those that were scammed might be a good idea here. Use all common terminology; the same phrases, same descriptors, same situations, same money transfers, etc. Uniformity here is key, I'd imagine. This is time to prove he conspired to scam everyone from email/pm number one. (I don't have an account on KLOV, but if there's a way to make a private, invite only thread for you all to get together on this, that would be perfect.)
Then, the person who suffered the highest financial loss should be the first person to call his/her local Secret Service office and describe the whole scam, what has gone on over the past few months, where it took place, how communications took place, their personal monetary transactions involved and the method of transmittal of funds, and all the false information and images given and fake items sent. More on this in a bit...
https://www.secretservice.gov/contact/field-offices
These offices cover many surrounding counties in various patterns, so it might be a good idea to call the one you think is local to you and ask if they cover your county. If they don't, or they have a smaller, more local field office, ask for their number and contact them. For example, the office I'd contact according to that list is based in San Francisco, but there are field offices in Sacramento and Fresno. So it's best to do some asking. This is important because mt friend said that according to the secret service, the crime that was committed falls under the jurisdiction of the field office of the victim, not the criminal.
BUT, before contacting said offices, he/she should have a fairly sizable list of all the others affected by this fraud as well. So, on KLOV, see if a list of all those affected, their hometowns, and how much they got scammed for can be gathered before calling the Secret Service office. Either way, if/when they ask who all has been affected, you'll know not only the info, but can present it to them however they might need. Again, teamwork and uniformity of information here is key.
Then, after the first person calls their local secret service office...everyone else that got scammed calls their local office. The idea is to flood both the IC3 website and the secret service with criminal complaints. Granted, that may not ultimately be necessary as my friend said that even if someone was scammed for as little as $500, if the same guy has done it multiple times to multiple people, a single field office will likely go after him. He mentioned an online puppy selling scam that they locked a guy up for recently that did just that. So, while each individual was scammed for a whole lot less per person than those on KLOV, they still went after the guy and got him.
Either way, as much information that can be given to these different federal departments as possible is the goal. Both the Secret Service and the FBI investigate and prosecute wire fraud. Also, by contacting each of the local field offices, there might be one office that's "super bored and would love to take up the case and pursue it for everyone, or there's one that's just better equipped to handle a case of such a scale", my friend's actual words.
Feel free to copy/paste this info into whatever thread on KLOV, or just PM it to each of the victims individually. Might be best to keep it away from his prying eyes. Either way, I think the drumbeat of justice will start to get louder if everyone starts contacting these entities.
Good luck everyone. It may take a while for this whole thing to come together and for charges to be levied, but stay the course and I think this guy will get his comeuppance.
