He detailed some of his planning leading up to the murder. He said that he was motivated by years of back pain and what he believed was a health insurance system working against him. He said that, once he learned that the UnitedHealthcare Company was holding an investor summit in Manhattan, he e-mailed company leadership posing as an investor to get information about where and when this meeting was taking place.
And that’s how he was able to confront Brian Thompson. Mangione also shared an observation with the judge that had clearly made an impression on him. He talked about how, while he was posing as a wealthy investor, leadership e-mailed him back within an hour, and he said that was in stark contrast to his interactions with insurers as a patient.



I don’t think he is. This happened just before the state trial, even though they dropped the federal murder charge.
IANAL, but I wonder if the admission is some sort of push to kill the NY trial due to double jeopardy?
Then again, I’m a random idiot on the Internet so I’m probably way off base.
I’ve seen a number of analysts on whether it would count on double jeopardy. Notably, NY prosecutors claim that it doesn’t.
I suspect that prosecutors would say that, but ultimately that would be the judge’s job, right?
That’s my understanding. I actually just saw an article today about where it stands. I believe any rulings on the matter can be appealed by either side, all the way up to SCOTUS.

A very strongly suspect that you’re right about appeals.
I think that this is going to get drug out for a very long time.
