Manhattan District Attorney Alvin Bragg held a news conference to announce the indictment of Luigi Manon on first-degree murder charges for the killing of Brian Thompson, CEO of United Healthcare. The charges include one count of first-degree murder and two counts of second-degree murder, one of which is classified as an act of terrorism. The maximum penalty for these charges is life without parole. The case was built through collaboration with various law enforcement agencies, including the NYPD and the FBI. The murder was described as a premeditated act intended to cause shock and intimidation in a busy area of New York City. Manon allegedly used a 3D-printed ghost gun to carry out the shooting. Ghost guns, which are untraceable and can be made using 3D printing technology, are becoming a growing concern in New York City and across the country. The DA's office and NYPD are actively working to combat the proliferation of these weapons. Manon was arrested in Pennsylvania and is awaiting extradition to New York.
