In a renewed effort to solve a long-standing mystery, federal agents recently conducted a meticulous search of Brian Cole Jr.’s home in Virginia. Cole faces accusations of planting pipe bombs in Washington, D.C., on January 5, 2021. This move signals a revival of an investigation that had been stagnant for several years.

Cole was apprehended in Woodbridge, Virginia, following his identification by federal authorities as the prime suspect in the case. He is believed to have planted the explosive devices near key locations such as the Republican and Democratic National Committee headquarters and the Capitol complex. His capture represents a significant advancement in a case that had previously seen little progress.

Jason Pack, a retired FBI special agent with experience leading Evidence Response Teams, explained to Fox News Digital that the search adhered to the standard protocol used in explosive cases. This methodical approach began with ensuring the area was cleared of hazards before collecting evidence, reflecting the seriousness with which investigators are treating the matter.

The operation commenced with a routine safety assessment, typical of federal procedures when dealing with potential explosives.

“The search of the Woodbridge residence is progressing with a careful and systematic approach,” Pack commented. “The involvement of explosive ordnance disposal experts, bomb technicians, and specialized K-9 units underscores that safety is the top priority.”

He explained that investigators must first clear the property of possible explosive hazards to protect personnel and preserve the scene before they can begin collecting evidence.

One of the clearest indications of the work underway came from the metal paint cans agents carried out of the home.

Pack said metal paint cans are a preferred method for collecting and transporting suspected explosive material because they limit contamination and protect volatile samples. The cans also allow forensic laboratories to analyze residues, components and chemical signatures that might connect a device to a specific individual or technique.

Once the scene is declared safe, evidence teams can move inside the home.

FBI Evidence Response Team members, guided by a federal search warrant and its attachments, typically handle the next phase of the search and use those documents to determine what they are authorized to seize.

Those categories include explosive components or precursor chemicals; tools or materials used to construct destructive devices; electronic devices such as phones, hard drives and laptops; records, notes or digital communications that could show planning, motive or knowledge; and items that confirm identity, occupancy or control of the residence.

In this investigation, agents are looking for evidence that establishes intent, capability and any links to the explosive devices planted on Jan. 5, 2021.

Once the evidence is collected, it moves into the long analytical phase of the investigation.

Any electronics seized will undergo digital forensics to recover communications, searches or location data that may reveal planning or coordination. Laboratories will also examine residues or components to determine whether they match the devices used at the Capitol complex, the RNC or the DNC.

Pack said the search in Woodbridge shows the FBI is treating the investigation as if it had just begun, which he said can “change the entire trajectory” of the case.

“I have been the fresh set of eyes on cold cases, and I worked them as if the crime happened that morning,” he said. “The initial investigators often do excellent work. A new perspective simply asks different questions and sometimes spots the detail that finally brings the guilty to justice.”

Pack said the U.S. Attorney’s Office is responsible for obtaining the warrants and court orders that move an investigation from suspicion to proof.

“When the immediate danger has passed, older cases often end up folded into the stack of files handled by overworked Assistant United States Attorneys who are already juggling emergencies of their own,” he said. “That can slow down warrants and subpoenas, not because anyone is dragging their feet, but because they are drowning in urgent matters.”

The same pressures hit FBI agents, Pack said, as new threats emerge each day and older cases get pushed back while “investigators run to the sound of guns.”

“There are only 12,000 FBI agents in the world, and that small group is responsible for handling every threat that comes our way,” Pack said. “When leadership pours fresh resources back into a case, the whole machine turns forward again. Sunlight finds what shadows hide, and a second look often makes all the difference.”

Cole had his first court appearance Friday after being arrested the day before and charged with transporting an explosive device in interstate commerce and with maliciously attempting to destroy property using explosive materials.

He has been speaking with investigators and reportedly admitted to planting the devices and expressing doubts about the outcome of the 2020 presidential election, a source close to the investigation told Fox News.
