According to court documents, in July 2025, Jacober possessed 50 pounds of dynamite, which he had hidden in a cave approximately 10 to 15 feet from a travel trailer where Jacober was residing. In 2021, Jacober was convicted in Kern County Superior Court of making a destructive device without a permit, a felony. As a convicted felon, Jacober was thus prohibited from possessing explosives. In addition, Jacober was in the process of manufacturing crystal methamphetamine in his trailer, where he possessed both finished product and methamphetamine in the process of changing from liquid to a crystal form. On November 24, 2025, Jacober pleaded guilty to the charges that gave rise to his sentence.
