NEW YORK -- Manhattan District Attorney Alvin L. Bragg Jr. and New York City Police Department Commissioner Jessica S. Tisch on Tuesday announced the indictment of Luigi Mangione, 26, for the murder of UnitedHealthcare CEO Brian Thompson in Midtown of Manhattan on Dec 4.

Mangione is charged in a New York State Supreme Court indictment with one count of murder in the first degree, two counts of murder in the second degree, and multiple counts on criminal possession of a weapon.

Mangione, an Ivy League graduate, was arrested in Altoona, Pennsylvania on Dec 9 in connection with the fatal shooting of 50-year-old Thompson.

Mangione is not going to fight extradition to New York, according to reports quoting his lawyer Karen Friedman Agnifilo.

Thompson was fatally shot in early morning outside the New York Hilton Midtown, as he was on his way to attend an annual investor conference there organized by UnitedHealth Group, the parent company of UnitedHealthcare.

The killing of Thompson has drawn an outpouring of public anger against private health insurers on social media.
