Most white collar investigations don’t begin with handcuffs. They begin with a records request sent to a bank, a quiet interview with a former employee, or a tip passed to a federal agency. By the time someone realizes they’re under investigation, prosecutors and agents may have been building their case for months. That gap between when scrutiny begins and when you find out about it is one of the defining features of how these cases unfold.
With more than 27 years of handling serious criminal defense cases in Seattle, I’ve seen how that early period before an attorney gets involved can shape everything that follows. Understanding the actual mechanics of a white collar investigation: which agencies are involved, what the stages look like, and what each signal means, gives you the foundation to respond intelligently rather than reactively.
How These Investigations Actually Begin
Federal white collar investigations rarely start with dramatic action. A whistleblower files a complaint. An internal audit surfaces transactions that don’t add up. A bank’s compliance department flags unusual wire activity and files a Suspicious Activity Report. A disgruntled business partner makes a call. The investigation begins quietly and stays that way while agents work through financial records before anyone is approached directly.
In Seattle, that initial work often runs through the FBI Seattle Field Office’s Complex Financial Crimes Squad, which handles cases ranging from embezzlement to multi-hundred-million-dollar investment fraud schemes. Most people don’t learn they’re under scrutiny until they receive a subpoena for documents, a formal target letter, or an unexpected visit from investigators.
Which Agencies & Courts Handle the Case in Seattle
Whether a case is federal or state-level matters enormously for how it proceeds. The two tracks involve entirely different agencies and courthouses.
Federal Cases
Federal white collar cases in Seattle are prosecuted by the U.S. Attorney’s Office for the Western District of Washington through its Economic Crimes Unit. That unit coordinates with a broad network of investigative agencies: the FBI, IRS Criminal Investigation, the SEC, the EPA Criminal Investigative Division, FINRA, and the Securities Division of the Washington Department of Financial Institutions. A case may draw on two or three of those agencies simultaneously, each contributing records, analysis, or witnesses. Federal proceedings, including grand jury proceedings, are handled at the federal courthouse at 700 Stewart Street in Seattle, which covers King County and the surrounding counties of Island, San Juan, Skagit, Snohomish, and Whatcom.
State-Level Cases
State-level allegations follow a separate path. When prosecutors charge a white collar matter under state law rather than federal statute, it typically goes to the King County Prosecuting Attorney’s Economic Crimes and Wage Theft Division, located at the King County Courthouse in downtown Seattle. That division handles investment fraud, mortgage fraud, embezzlement, and public corruption cases. The procedures, timelines, and standards differ significantly from the federal process, which is one reason why knowing which track you’re on matters from day one.
From Document Requests to Search Warrants
Investigators almost always build a document foundation before approaching the person at the center of the inquiry. Grand jury subpoenas and financial records subpoenas go to banks, brokerages, employers, and payment processors, often without the subject’s knowledge. Agents then work with forensic accounting analysts to trace money movement, match representations against actual transactions, and identify gaps or inconsistencies. Before approaching the primary subject, investigators typically interview associates (colleagues, employees, accountants, or business partners) to fill in details about how money or information moved and to gauge whether witnesses will cooperate or corroborate a particular version of events.
A search warrant is a later-stage tool. It requires investigators to show a federal judge or magistrate that there’s probable cause to believe evidence of a crime will be found at a specific location. When agents execute a warrant at a home or office, they can seize computers, phones, external drives, paper records, and any other materials named in the warrant. A search warrant visit is one of the clearest signals that a case is serious and moving toward a charging decision.
The Grand Jury, the Target Letter, & the Charging Decision
Federal prosecutors present evidence to a grand jury, a panel of citizens who hear only the government’s case and decide whether to return an indictment, which is a formal document charging a person with a federal crime. The person under investigation has no right to appear before the grand jury, no right to present a defense, and typically no insight into what evidence is being shown to the panel.
A target letter is a formal written notice that prosecutors believe there’s substantial evidence connecting the recipient to a crime and that the recipient is a focus of the investigation. Receiving one doesn’t automatically mean an indictment is coming, but it signals a level of prosecutorial attention that demands an immediate and careful response. A subpoena to testify before a grand jury, by contrast, might place someone as a witness rather than a target, though that status can change depending on what investigators learn.
Not every investigation ends in charges. Prosecutors sometimes reach a point where the evidence doesn’t support moving forward, or where a proffer agreement (a formal meeting in which a subject provides information in exchange for potential consideration) changes the direction of the case. A proffer is a significant strategic decision that should never be made without experienced counsel, because statements made during one can be used under certain circumstances even if no deal is reached.
What to Do If You Believe You’re Under Investigation
The instinct to explain yourself to investigators is understandable. It’s also one of the most consequential mistakes someone can make. Any statement, even a completely truthful one, can be used as evidence and characterized in ways the speaker didn’t intend. Agents are trained at building rapport and asking questions that surface information without appearing to do so. The safest position is a straightforward one: you’re happy to cooperate, and you’ll do so with your attorney present.
Preserving documents is equally important. Destroying, altering, or deleting records after learning that an investigation is underway is a separate federal crime. Obstruction charges can be added on top of whatever underlying allegation prompted the investigation, and they’re often harder to defend because the conduct is so visible. Don’t delete emails. Don’t alter spreadsheets. Don’t instruct others to do so.
