If the case goes back to 2010, that means Big U is/was probably an informant too. He just went too far with his crimes
It's not that. I know people think that, but I have studied criminal indictments for like 15 years. It's someone who was around, who was able to give investigators a good look at when all this started, which they then confirm with other info, like when the non profit was founded or whatever.
They don't surveil for 15 years. I mean, maybe U was an informant, lots of OG's pass info from time to time. But, the fact it goes back to 2010 just means they have a cooperating witness who can give them that time. Like it you read a Chapo Guzman indictment, it will start back in 2006 or whatever, that just means they have evidence, that he was trafficking drugs as far back as that year. Most RICO indictments go back way further than when the actual person was being investigated.
it's as simple as the feds interviewing a cooperators, and they say.
"
about what year did this start?"
and a lot of people don't have that kind of memory, so they kind of piece together and say
"well my son was born around that time, so it must have been around 2010"
Then the investigators work backwards to fill in the full picture. They find documents and piece together other killings tied to the case. And they present a full picture of a criminal organization, rather than isolated incidents. Fed investigations like this are around 18 months. But because it's federal, RICO, they can go back as far as they want or need to, to give the full picture
