On Monday, a Santa Barbara County man confessed to bombing a courthouse in 2024 after law enforcement took his firearms earlier that year. Nathaniel James McGuire, aged 22, pleaded guilty to using a weapon of mass destruction and malicious destruction of a building through explosive means, as reported by the U.S. attorney’s office in Los Angeles. In his plea agreement, McGuire stated the bombing aimed to kill sheriff’s deputies in Santa Maria, injuring three individuals and causing significant damage to the building.
McGuire faces a potential life sentence at his hearing scheduled for March 1. His attorney did not provide immediate comments.
“This defendant’s brazen act of terror caused physical, structural, and emotional devastation. It had the potential for tragic outcomes,” commented First Assistant United States Attorney Bill Essayli. “Bomb attacks against law enforcement and other government officials require accountability and severe punishment.”
McGuire admitted to throwing a backpack with an explosive past the courthouse security area on September 24, 2024, targeting Santa Barbara sheriff’s deputies. The backpack slid to the feet of a victim and exploded outside a courtroom. Accompanied by shouts of “Liberty or death,” he threw the bag, according to authorities.
He was present at the courthouse due to a firearm charge from his arrest on July 28, when deputies found him carrying an unregistered, loaded revolver. After the bombing, McGuire returned to his vehicle for further weapons and intended to re-enter to attack more individuals.
He was arrested while trying to access a red Ford Mustang parked at the scene. A witness reported to The Times about the explosion, detailing the smoke-filled courthouse and a man with ammunition falling from his pockets as officials detained him. Shane Mellon, a company representative scheduled to appear in court, mentioned hearing screams during the incident, believing the situation could have been much more severe.
The bombing resulted in approximately $35,000 in damages, leading to the courthouse’s temporary closure. McGuire admitted the attack was retaliation for alleged government wrongdoings.
Investigators found bomb-making materials at McGuire’s home. Assistant Attorney General for National Security, John A. Eisenberg, stated, “McGuire launched a vicious, terroristic assault on a court intending to kill officers and a judge. His attack injured three people, and without swift court security and law enforcement response, the outcome could have been far worse.”
