I would assume the bulk of his assets would be seized by the Mexican gov't.
You might be surprised how relatively *small* his physical and true $$ assets are.
I followed the trial since about halfway through. The literal majority of his ongoing revenue was spent paying for trustworthy security forces. Monthly revenue was cycled immediately into a combination of security forces and purchasing fresh inventory. A third major cost center was paying off government police and military. Any significant physical and $$ assets would be seized by Mexico. I am reasonably confident no US agency has a valid legal claim on anything not seized within the physical USA
it will take less than a week for him to gain full control of that facility. normally it would take less than a day in a regular pen but this place is a tad more stringent. funds are being transferred to prison officials bank accounts as we speak. he cannot escape but will get the best room they have with all the amenities.
