UnitedHealthcare CEO Murder Highlights Threat of 3D-Printed 'Ghost Guns'

Luigi Mangione, accused of killing Brian Thompson, allegedly used a partially 3D-printed firearm, raising concerns about untraceable weapons in violent crimes.

Police arrested Luigi Mangione, a 26-year-old software engineer, for the December 4 murder of UnitedHealthcare CEO Brian Thompson in New York City.
Mangione allegedly used a Chairmanwon V1, a partially 3D-printed 'ghost gun,' which lacks a serial number and is untraceable by law enforcement.
Authorities found a manifesto with Mangione criticizing the U.S. health insurance industry and bullet casings inscribed with messages targeting healthcare practices.
The case underscores the growing prevalence of ghost guns in violent crimes, with tens of thousands recovered from crime scenes in recent years.
The Biden administration's 2022 regulations on ghost gun kits are being challenged in the Supreme Court, with a decision expected next year.
