Spearfish男子获刑5年11个月：家中藏9枚自制爆炸装置与未登记消音器
美国司法部南达科他州联邦检察官办公室宣布，南达科他州 Spearfish 市45岁男子 Cole Nygaard 因两项持有未登记枪支罪名，被联邦地区法官 Camela C. Theeler 判处5年11个月联邦监禁，其后3年监督释放，并须向联邦犯罪受害人基金缴纳200美元特别评估费。量刑于2026年10月19日进行，Nygaard 已于今年7月20日认罪，宣判后立即被移交联邦法警局羁押。
案情始于2024年1月：执法人员在南达科他州 Lawrence 县拦查一辆汽车时，在车内发现3支装有消音器的枪支，Nygaard 当时是车上乘客；这些消音器没有任何标记或序列号，也未按法律要求在国家枪支登记与转让记录（NFRTR）中登记。2026年1月27日，执法人员在得知 Nygaard 正在制作管状炸弹、并表示要用它们对付他人和一家企业后，搜查了他的住所，当场发现9枚他自制的简易爆炸装置，包括金属管状炸弹和一枚可组装成破坏性装置的受害者触发式金属盒；其中一枚较小的装置在执法人员进行安全处置时引爆，所幸因防护措施得当无人受伤。
搜查还在其住所厨房、车库和三辆车内发现多枚管状炸弹，在一间秘密枪房内查获多支枪支和数千发弹药，另在住所其他位置查获19支枪支——包括一支被改装成可发射12号霰弹的信号枪——以及爆炸物前体硝酸钾、多本讲解如何制造破坏性装置、报复他人和投毒的书籍。检察官办公室称，Nygaard 在持有这些枪支与爆炸装置期间每天吸食冰毒。
此案由烟酒火器与爆炸物管理局（ATF）、南达科他州刑事调查局与 Spearfish 警察局联合调查，助理联邦检察官 Benjamin Schroeder 负责起诉。联邦检察官 Ron Parsons 在宣布量刑时公布了上述案情。
Spearfish Man Sentenced to 5 Years and 11 Months: Nine Homemade Explosive Devices and Unregistered Silencers Found at His Home
The U.S. Attorney's Office for the District of South Dakota announced that Cole Nygaard, 45, of Spearfish, South Dakota, was sentenced by U.S. District Judge Camela C. Theeler to five years and 11 months in federal prison, followed by three years of supervised release, on two counts of possession of an unregistered firearm. He was also ordered to pay a $200 special assessment to the Federal Crime Victims Fund. The sentencing took place on October 19, 2026; Nygaard had pleaded guilty on July 20, 2026, and was immediately remanded to the custody of the U.S. Marshals Service.
The case began in January 2024, when officers stopped a vehicle in Lawrence County, South Dakota, and found three firearms fitted with silencers; Nygaard was a passenger. The silencers bore no markings or serial numbers and were not registered in the National Firearms Registration and Transfer Record (NFRTR) as required by law. On January 27, 2026, after learning that Nygaard was making pipe bombs and had indicated he would use them on others and a business, law enforcement searched his residence and found nine improvised explosive devices he had manufactured, including metal pipe bombs and a victim-operated metal box that could be assembled into a destructive device. One of the smaller devices detonated while officers were rendering it safe; thanks to precautionary measures, no one was injured.
The search also recovered pipe bombs throughout the residence, including in the kitchen, garage, and each of his three vehicles; several firearms and thousands of rounds of ammunition in a secret gun room; 19 more firearms elsewhere in the home, including a flare gun converted to fire 12-gauge shotgun shells; containers of the explosive precursor potassium nitrate; and books on building destructive devices, getting revenge, and poisoning people. Prosecutors said Nygaard was a daily user of methamphetamine while in possession of the firearms and devices.
The case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the South Dakota Division of Criminal Investigation, and the Spearfish Police Department, and was prosecuted by Assistant U.S. Attorney Benjamin Schroeder. U.S. Attorney Ron Parsons announced the sentence.
