The investigators arrested three men and confiscated handguns and attack weapons in a house in Northern California, where they found a fully functional 3D printing workshop to produce parts for the production of firearms in private pieces, which are also known as Ghost Guns.
Ghost weapons that have no serial numbers and are difficult for law enforcement officers are produced with fire weapons parts that are sometimes sold in kits. With limited exceptions, the sale or transfer of ownership to self -made or self -organized firearms is prohibited according to the Ministry of Justice of the State Ministry of Justice under California law.
At the beginning of this month, the Department of the Sheriff of Yuba County initiated an investigation of the alleged production of firearms and the illegal distribution of these weapons, which is for sale. The Sheriff's problem -oriented police team believed that the weapons were produced using the 3D printing technology after a press release of a sheriff.
On Friday, the investigators had a search command in the house in the 1800 block of the Waterfall Drive in the city of Linda south of Marysville. The probation department of the Yuba district helped the Sheriff investigators to serve the search command.

In the home, Detectives discovered a “full company 3D printing workshop” with manufacturing tools, the officials of the sheriff said in a press release. The investigators also found eight pistols, several 3D printed handgun frames, four attack weapons, a rifle and various firearm parts.
Detective arrested three Marysville men aged 19, 27 and 38 years as a result of the examination. The Sheriff officials said that the suspects were booked in the prison of Yuba County for several charges for firearms.
Last year, this area of Northern California experienced the consequences of ghost weapons. In December, an annoyed man, who was armed with a Ghost Gun, shot two kindergarten teachers who were seriously wounded on the campus in the Feather River Adventist School in Oroville.

Butte County's office said that the 56 -year -old Greg Litton used a privately produced Glock 19 pistol to shoot the two boys before turning the weapon on himself. The investigators learned that the ghost weapon, which was used in faith at the Schießerei of the school shots, was sold to the shooters by a convicted criminal in Arizona.
Two months before the school announcement, the California Attorney General Rob Bonta warned that the Ghost Gun Market increasingly shifted towards “Products and Services via Skip-the-Background check”. He said this was designed in such a way that people illegally produce ghost weapons, without a background test or other protective measures with 3-D printers, computer-numerical control waste machines and similar machines for ghost weapons.
