California Attorney General Rob Bonta has filed a lawsuit against two companies and more than 100 individuals, accusing them of unlawfully distributing computer code used for 3D-printing "ghost guns," the attorney general's office said in a Feb. 6 statement. Ghost guns refer to untraceable firearms manufactured without valid serial numbers. The lawsuit, filed Friday in the Superior Court of the State of California in San Francisco, targets Florida-based Gatalog Foundation Inc., the owner of thegatalog.com, CTRLPew LLC, and the owner of ctrlpew.com. Individual defendants in the case include people associated with these companies. In addition to accusing them of distributing the computer code for 3D printed firearms and prohibited accessories, the defendants promoted and facilitated the unlawful manufacture of these devices, all of which violated state regulations, according to the lawsuit.
