A Rockwall man, Joshua Javier Menjivar, 20, has been charged with unlawful possession of an unregistered firearm, announced U.S. Attorney for the Northern District of Texas, Leigha Simonton. Menjivar made his initial appearance before U.S. Magistrate Judge Renée Harris Toliver on Wednesday.
According to the criminal complaint, Menjivar allegedly imported machinegun conversion devices, known as Glock switches, from China. These devices can convert firearms to fire automatically, making them highly dangerous. One of these devices was found installed in an untraceable "ghost gun" at Menjivar's residence.
The investigation began on May 16 when Customs & Border Protection agents intercepted a suspicious package containing four Glock switches bound for Menjivar’s home. Further investigation revealed that between May 2023 and May 2024, approximately 35 suspicious packages were delivered to Menjivar’s address. These packages were manifested as various household items and addressed to fictitious individuals.
On June 10, ATF agents collected trash outside Menjivar’s home, finding items consistent with illicit firearms shipments. On June 20, agents executed a search warrant at his residence, discovering a ghost gun with a switch, five additional switches, 72 rounds of assorted ammunition, two commemorative bitcoins, and various firearm accessories. Menjivar allegedly admitted to possessing the switches and understanding how they worked.
The investigation was conducted by the Bureau of Alcohol, Tobacco, Firearms, & Explosives’ Dallas Field Division, Homeland Security Investigations’ Dallas Field Office, the Dallas Police Department, the Rockwall County Sheriff’s Department, and U.S. Customs & Border Patrol. Assistant U.S. Attorney Robert Withers is prosecuting the case.
