A retired NYPD detective revealed that the silencer on the 3D-printed gun allegedly used by Luigi Mangione to execute UnitedHealthcare CEO Brian Thompson was like nothing he had ever seen in 25 years on the force. Detective Sgt. John Griffin was investigating the high-profile December 2024 Midtown slaying and was left stunned by the deadly suppressor fitted to the 9-millimeter handgun.
