Luigi Mangione, accused of murdering UnitedHealth Group CEO Brian Thompson, has been extradited from Pennsylvania to New York under heavy police protection. Mangione allegedly shot Thompson outside a Manhattan hotel during an investment event. Although he initially resisted extradition, a judge approved the move. Federal and state charges include stalking and murder, with potential consequences including life imprisonment or the death penalty. Additionally, a notebook containing threatening messages toward the insurance sector was found during Mangione’s arrest.
