Nathaniel James McGuire, 22, has pleaded guilty to charges stemming from a bombing at a Santa Maria courthouse in September 2024. McGuire detonated an explosive device in retaliation for law enforcement officers seizing his firearms earlier that year. He threw a backpack containing the device into the courthouse before attempting to retrieve firearms and Molotov cocktails from his car. Law enforcement apprehended him before he could re-enter the building. The attack injured three people and caused an estimated $35,000 in damages. According to his plea agreement, McGuire intended to kill sheriff's deputies and a judge. He has been held in federal custody since the incident. McGuire faces a maximum sentence of life in prison. His sentencing hearing is scheduled for March 1. The National Center for State Courts reported that federal judges, prosecutors, and court officials faced over 4,500 threats in 2021, a 400% increase since 2015.
