If they conclude that state law has been violated, the question is: What next? Contrary to recent assertions from some federal officials, states can prosecute federal officers for violating state criminal laws, and there is precedent for that.
Although federal officers do have immunity in some circumstances, that protection applies only if their actions were authorized under federal law and“necessary and proper” in fulfilling federal duties. When federal officers violate federal law or act unreasonably when carrying out their duties, they can face state charges.
States have a long history of prosecuting federal officials for allegedly using excessive force on the job. And when federal courts agree that the force may not have been legally justified, they have allowed the state prosecution to proceed.

Okay, I admit that’s an interesting fact I wasn’t aware of. However, based on the Wikipedia article you linked to, I seriously doubt one could expect the charge to hold up against ICE superiors. It might work to charge the other officers that were there when the woman was killed, but I would bet charging anyone absent of the direct event would be deemed too remote.
Case law in the US has at least one example of someone being convicted of felony murder simply for letting another person borrow their car with no other significant connection to the case.

John Oliver has a great segment on how fucked up this law is: https://youtu.be/Y93ljB7sfco
That said, you’re right in that it is highly unlikely any of the higher-ups will be held responsible.
Nor should they be under this type of charge. I’m sure there are other charges that can be brought against them though.
