The man charged in connection to the shooting death of UnitedHealthcare CEO Brian Thompson is believed to have 3D printed the gun he was allegedly found with, police said.

20 3D-printed Glock-style parts, some of which had a Gucci label on them. A 3D-printed AR-15-style firearm that looked similar to a toy Nerf gun.

3D printed guns a global problem, CPS says Lawson said 3D firearms function in the same way that regular guns do, and the increased use and production of 3D printed guns is a global problem.
