Apparently the researchers in question don't have tenure. If that is so, RIP to their achedemic careers right now.

That seems optimistic. Scientific fraud is caught all the time and basically never results in anything happening. The university here repeatedly signed off on this so it's institutionally culpable. Normally when bad stuff happens in research academics just all blatantly deny anything is wrong and dare you to do anything about it.

I wonder if potential collaborators will come to light, from UMN or other universities.
