A Ukrainian national, Yaroslav Vishnevski, is convicted in the United States following authorities’ findings tied to a ghost gun and firearm-silencer operation. According to one report, Vishnevski had completed Air Force officer training in Ukraine before the case. Prosecutors charged him with multiple federal offenses in connection with manufacturing or possessing firearms made through 3D printing and with possession of illegal silencers. The report states that authorities found evidence of a 3D-printed “ghost gun” operation and also located silencers that were allegedly sourced from China. The conviction results from a federal case in which he is found guilty on five counts, as described by the outlet covering the matter. The reporting also indicates that the case involves firearms that are produced without serial numbers, and that the silencers fall under U.S. legal restrictions. The sources provided do not include sentencing details or the full factual timeline leading to the arrest.
