San Jose teen accused of 3D printing 27 ghost guns in bedroom, DA says

SAN JOSE, Calif. (KGO) -- A San Jose teenager is accused of manufacturing ghost guns in his bedroom, according to the Santa Clara County District Attorney's Office.

Investigators seized 27 finished or almost finished firearms from the home of the 18-year-old suspect's home, authorities said.

Some were modified to function like machine guns, a felony under California law.

Prosecutors say the suspect used two 3D printers in his bedroom to manufacture most of the weapons. One additional illegal handgun was also recovered.

The case was investigated by the district attorney's Gun Violence Task Force in partnership with the San Jose Police Department, including its GHOST and MERGE units.

The suspect was arraigned at the Hall of Justice in San Jose Thursday on felony charges, including possession of a machine gun and unlicensed manufacturing of firearms. If convicted, he faces prison time. He is expected back in court next week.

"There is a black market of weapons thriving right under our noses," District Attorney Jeff Rosen said. "Investigators and their law enforcement partners have taken off the streets an arsenal of untraceable, illegal and deadly weapons."

Since 2024, the Santa Clara County Gun Violence Task Force has seized or confirmed the relinquishment of 405 guns, prosecutors said.
