Luigi Mangione, the man accused of gunning down the CEO of UnitedHealthcare in New York City, is breaking his silence on the outpouring of support since his arrest in Pennsylvania on murder and terrorism charges last month. Mangione is currently awaiting trial at the Metropolitan Detention Center in Brooklyn. "I am overwhelmed by — and grateful for — everyone who has written me to share their stories and express their support," Mangione wrote in a statement published on his website, which was launched by the 26-year-old's legal defense team in New York.
