Luigi Mangione, the suspect in the shooting death of UnitedHealthcare CEO Brian Thompson in New York, is fighting his extradition from Pennsylvania, where he was arrested by authorities Monday. Mangione’s lawyer says they are waiting for more evidence related to the charges against Mangione in New York.

Meanwhile, the NYPD warned healthcare executives earlier this week after a “hitlist” of CEOs was posted online. “Wanted” posters popped up across New York this week featuring photos of health insurance CEOs, as the case has galvanized public condemnation of the health insurance industry.
