FBI Revitalizes Investigation Into 2021 DC Pipe Bombings Following Arrest
WASHINGTON, D.C. — Federal investigators have intensified their efforts in the investigation of pipe bombs planted near the U.S. Capitol complex and political party headquarters in January 2021, following the recent arrest of Brian Cole Jr. in Woodbridge, Virginia. The FBI’s methodical search of Cole’s residence this week marks a significant development in a case that had largely remained dormant for nearly five years.
Agents conducted a meticulous sweep of the Virginia home, employing explosive ordnance disposal technicians, bomb technicians, and specialized K-9 units to ensure the safety of personnel and preserve the integrity of the evidence. Retired FBI special agent Jason Pack, who has extensive experience leading Evidence Response Teams, explained that the operation adhered to the standard protocols used in explosive investigations, beginning with hazard clearance before evidence collection.
“Federal agents are following a deliberate and familiar sequence as the search of the Woodbridge residence continues,” Pack said. “The presence of explosive ordnance disposal technicians, bomb techs and specialized K-9 teams indicates that the first priority is safety.” The agents’ cautious approach reflects the gravity and complexity of the case, treating it with the same urgency as if the incident had just occurred.
During the search, agents removed metal paint cans from the home—containers preferred for transporting suspected explosive materials due to their ability to limit contamination and protect volatile samples. These cans enable forensic laboratories to analyze residues, components, and chemical signatures that may link the devices to specific individuals or manufacturing techniques. Once the property was declared safe, the FBI Evidence Response Team proceeded with a thorough collection of evidence under a federal search warrant.
Cole’s arrest last week represents the first major breakthrough in the investigation into the pipe bombs placed on January 5, 2021, near the Capitol, the Republican National Committee (RNC), and the Democratic National Committee (DNC) headquarters. The devices were discovered in the tense lead-up to the January 6 Capitol riot, raising alarms about potential coordinated attacks on critical political institutions.
The FBI’s renewed push in this case underscores how fresh investigative perspectives can breathe new life into stalled probes. The agency’s approach aligns with established procedures outlined by the Federal Bureau of Investigation’s explosives investigation guidelines, emphasizing safety, evidence preservation, and meticulous analysis.
Authorities have not publicly disclosed all details of the evidence uncovered during the search, but the careful handling of materials suggests a focus on linking Cole definitively to the pipe bombs through forensic means. The investigation remains ongoing, with federal prosecutors expected to review the collected evidence as they prepare for potential charges.
The case has drawn national attention not only because of the nature of the devices and their proximity to key government sites but also due to the prolonged period without significant leads. The FBI’s recent developments highlight the importance of persistence and the value of re-examining cold cases with new resources and technologies.

The FBI continues to urge the public to report any information related to the case through its official channels.
This revitalized investigation serves as a reminder of the ongoing challenges law enforcement faces in combating politically motivated violence and the critical role federal agencies play in safeguarding the nation’s capital and democratic institutions.
