Luigi Mangione was arrested in Pennsylvania on Dec. 9, 2024, in connection with the murder of Brian Thompson, the chief executive of UnitedHealthcare, the previous week.
Stephen Hemsley, chief executive of UnitedHealth Group, left, was among the executives defending insurers’ practices at congressional hearings in January. To his left were David Joyner, chairman of CVS Health, and Gail Boudreaux, chief executive of Elevance Health.
Mr. Mangione faces federal charges of stalking that resulted in the death of a health insurance executive. A guilty plea could close the federal case — and complicate a separate state murder trial.
