The suspect accused of killing UnitedHealthCare CEO Brian Thompson has pleaded not guilty to New York state murder and terrorism charges.
Luigi Mangione, 26, appeared in court on Monday to be arraigned on 11 state criminal counts, including murder a crime of terrorism.
As well as the state-level charges, he is also accused of federal (national-level) stalking and murder offences that could lead to a death penalty sentence.
Prosecutors allege that Mr Mangione shot Mr Thompson in central Manhattan before going on the run. Authorities later arrested him at a McDonald's in Pennsylvania.
