I don't know the correct terms, but I know building contractors get paid two ways. One way, is at the end of a job, especially if it is a house with a mortgage. The contractor will cover all costs, then get reimbursed, materials plus labor. Another fairly common way is to have an escrow or account or credit card available so the contractor can purchase building supplies as he/she goes. That way they do not incur building supplies costs. They sometimes are paid weekly or at the end of the job. Is it possible, he was using an account/escrow/etc for more than building supplies? Perhaps, to purchase supplies for his own home renovation? I posted a little earlier, but, I do wonder if there are internal reasons for protecting IK. I think his link to Sam may be more from an informant/undercover role and they are trying not to blow the original case (reason why he was there in the first place) and years of work? By the time he was arrested in Texas, his "handlers" stepped in and identified him. That is why it is hush-hush. And they need to protect him in prison...no one likes a agent or snitch. And by his arrest, perhaps, the pressure will be on others and someone may crack (not knowing if he is talking) or let down their guard. Often in an undercover case, there is a whole process to extricate someone from an investigation. Sometimes, it can take a few months for Bureaucrats to process paperwork to close a case. Often, innocent people get injured or killed in the process and the agent has to stay quiet. It wouldn't be to hard to have one of the people "paying him" for his "construction work" to nail him on a charge of access fraud. It is not unreasonable to get him to a wedding in another state to protect him, too...
Sam may just be a form of collateral damage...
