“Federal agents are following a deliberate and familiar sequence as the search continues at the Woodbridge residence,” Buck said. “The presence of EOD technicians, bomb technicians and specialized K-9 teams indicates that the first priority is safety.”

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

One of the clearest signs that work was underway came in the form of metal paint cans carried out by customers from home.

Buck said metal paint cans are the preferred method for collecting and transporting suspected explosive materials because they limit contamination and protect volatile samples. The cans also allow forensic laboratories to analyze residues, components and chemical signatures that may link the device to a specific individual or technology.

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, usually handle the next stage of the search and use those documents to determine what they are allowed to seize.

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

Buck said the search at Woodbridge shows the FBI is treating the investigation as if it had just begun, which he said could “change the entire course” of the case.

“I had a new set of eyes on her Cold cases“I worked with them as if the crime had happened that morning,” he said. Primary investigators often do an excellent job. A new perspective simply asks different questions and sometimes identifies details that finally bring the guilty person to justice.

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

“When the immediate danger is over, old cases often end up in a pile of files handled by overworked assistant U.S. attorneys who are already handling their own emergency cases,” he said. “This can slow down search warrants and subpoenas, not because anyone is slowing down, but because they are drowning out urgent matters.”

The same pressures are on FBI agents, Buck said, as new threats emerge every day and old cases are pushed back as investigators “run to the sound of weapons.”

“There are only 12,000 FBI agents in the world, and this small group is responsible for dealing with every threat that comes our way,” Buck said. “When leadership returns new resources to a case, the whole machine moves forward again. Sunlight detects what the shadows hide, and a second glance often makes a big difference.”
