Luigi Mangione's Gun and Fingerprints Tie Him to UHC CEO Murder

Luigi Mangione, arrested in Pennsylvania, is suspected of murdering UnitedHealthcare CEO Brian Thompson in New York. NYPD linked Mangione to the crime through fingerprints and a ghost gun matching shell casings at the scene. Mangione's writings, found with him, allegedly detail plans to kill the CEO, citing grievances against the healthcare system. He faces second-degree murder charges and is challenging extradition to New York. His defense attorney claims there's no evidence linking him to the crime, while New York authorities seek a governor's warrant for his extradition.
