August 10, 2025 – A federal grand jury returned a four-count indictment on Thursday, August 7, 2025, against Matthew Henry Jacober, 43, of Bakersfield, charging him with being a felon in possession of explosives and ammunition and manufacturing methamphetamine, Acting U.S. Attorney Kimberly A. Sanchez announced.

According to court documents, Jacober possessed and improperly stored 50 pounds of dynamite and 25 rounds of shotgun shells. He was also in the process of manufacturing crystal methamphetamine at his residence in a remote area of Bakersfield. Jacober had previously been convicted in Kern County Superior Court of making a destructive device without a permit, a felony. As a convicted felon, he was prohibited from possessing explosives and ammunition.

This case is the product of an investigation by the Federal Bureau of Investigation with assistance from the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Kern County Sheriff’s Bomb Squad, and the Kern County Fire Department. Assistant U.S. Attorney Karen Escobar is prosecuting the case.

If convicted of the drug offense, Jacober faces a mandatory minimum prison term of five years in prison and a maximum term of 40 years, along with a $5 million fine. If convicted of being a felon in possession of explosives, he faces a 10-year prison term and, if convicted of being a felon in possession of ammunition, he faces a 15-year prison sentence. Both of these offenses also carry a $250,000 fine. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
