I’m thinking red herring.
Why?
https://www.healthcarefinancenews.com/news/unitedhealthcare-ceo-brian-thompson-fatally-shot-new-york
From the above...
“...Prior to this role, he served as CEO of UnitedHealthcare government programs including Medicare and Retirement and Community & State. Before leading government programs, Thompson served as CEO of UnitedHealthcare Medicare & Retirement. “
And note that the info is found in the last paragraph of the article.
Also, he only shot twice, according to the several reports I read.
How did the police come up with three words on three casings?
