SACRAMENTO, Calif. (AP) — Two Sacramento brothers were charged Thursday with making hundreds of illegal, untraceable firearms as part of what law enforcement officials said was a wide-ranging network designed to skirt federal laws.

Luis Cortez-Garcia, 44, and Emiliano Cortez-Garcia, 37, were indicted by a federal grand jury in Sacramento on multiple charges of unlawful manufacturing and sales of firearms including short-barreled rifles, machine guns, and silencers. Emiliano Cortez-Garcia is also charged with being a felon in possession of firearms.
