The suspect in the killing of the UnitedHealthcare CEO may have plans to waive extradition, according to New York County District Attorney Alvin Bragg. In a Friday press briefing with New York Mayor Eric Adams on an unrelated matter, District Attorney Bragg said the NYPD will "continue to press forward on parallel paths," whether Luigi Mangione waives or contests extradition. UnitedHealthcare CEO Brian Thompson, who was killed last week, was described as kind and brilliant by UnitedHealth Group CEO Andrew Witty in a guest essay published in The New York Times. The killing has been viewed as a violent expression of widespread anger at the insurance industry. Witty said people in the company were struggling to make sense of the killing, as well as the vitriol and threats directed at colleagues. Police have said Mangione was found with a three-page letter in which he lamented the high cost of health care in the U.S. and singled out UnitedHealthcare for its profits and size. The company, a division of UnitedHealth Group, is the largest U.S. health insurer. Mangione is being held in Pennsylvania and intends to plead not guilty to a murder charge in New York, his lawyer has said.
