FBI Launches Probe Into Suspected Targeted Terror Attack in Boulder

Here’s the bottom line: federal agents have descended on Boulder, Colorado, after what authorities now suspect was a deliberate, targeted terror attack. In the early hours of June 1, locals reported an explosion near the Boulder Municipal Courthouse. The Boulder Police Department promptly cordoned off the surrounding blocks, while the FBI’s Denver Field Office mobilized its Joint Terrorism Task Force. According to official statements and law enforcement sources, no group has yet claimed responsibility, but investigators believe the blast was aimed at a specific government building rather than a random public area.
At roughly 3:45 p.m. local time, courthouse employees spotted smoke billowing from the northern stairwell’s stairwell doors. Surveillance footage later revealed a lone individual—wearing dark clothing and a backpack—placing what appeared to be an improvised explosive device before fleeing the scene. Bomb technicians from the Denver Metro Threat Reduction Team rendered the device inert, and early forensic analysis indicated traces of military-grade explosives. FBI spokeswoman Maria Salazar confirmed in a June 2 press briefing that the bureau has executed multiple search warrants in Boulder County, including a residential property in Superior where electronic devices and possible manifestos were seized for further review.
Sources familiar with the case tell TMZ that cell-site data has placed at least two persons of interest within a half-mile radius of the courthouse in the days leading up to the strike. Investigators are now combing through social media accounts and financial records to establish motive and potential accomplices. The Department of Homeland Security has been looped in, with counterterrorism analysts assisting on behavioral indicators and threat assessment. Meanwhile, Mayor Sam Weaver issued a public reassurance: “Our community’s resilience is unwavering. We stand with law enforcement and citizens to ensure safety and transparency.”
Despite heightened anxiety, local businesses have reopened under a visible police presence, and the University of Colorado Boulder intensified campus security measures. The FBI has also set up a tip line, urging anyone with information—no matter how minor—to come forward. According to Reuters and CNN, the bureau is treating this as a “targeted act of terror,” a classification that carries significant federal sentencing implications if arrests are made.
Today’s developments mark only the latest twist in a rapidly evolving investigation. Questions remain about the attackers’ identity, whether this was part of a broader conspiracy, and the possibility of additional threats. And there you have it. Make of that what you will.
