Corporate Investigations
Most Internal Investigations Do Not Fail in the Interview Room
David P. Frizell, Jr., CFE · August 21, 2026
By the time an investigator sits down with an employee for a formal interview, much of the success or failure of the investigation may already have been determined. The problem is rarely a lack of good intentions. It is usually the opposite. A serious allegation surfaces and responsible people want answers. A supervisor asks a few questions. Human Resources checks with several employees. Someone forwards an email chain. A manager quietly asks another employee what they have heard.
Each step may seem reasonable. Together, they can make determining the facts considerably more difficult.
Witnesses begin comparing recollections. People hear how others have described events. The subject of the allegation may learn what is being examined and what evidence is known. Electronic or documentary evidence may be handled without a preservation strategy. Assumptions can begin to harden into accepted facts before anyone has established what actually occurred.
That is why I frequently tell corporate clients that I need to be one of their first calls when a potentially serious matter surfaces. That does not mean every concern requires an outside investigator, or even a formal investigation. It means that the earliest decisions can affect everything that follows.
A preliminary assessment is appropriate – and often essential. Leadership needs enough information to understand the source and nature of the concern, determine who already knows about it, assess whether specific people have been identified, and understand what steps have already been taken.
What leadership should avoid is allowing that assessment to become an informal pre-investigation.
There is an important distinction.
A preliminary assessment is designed to understand the issue well enough to decide what should happen next. A pre-investigation begins trying to determine what happened before the organization has established an investigative strategy, identified the appropriate people to conduct the work, or considered how evidence and confidentiality should be protected.
The distinction matters because interviews are not simply conversations. A well-conducted investigative interview is a truth-seeking process. It requires preparation, an understanding of the available evidence, careful sequencing of questions, attention to what is said and what is not said, and the ability to pursue inconsistencies without prematurely disclosing information. The interviewer must remain open to more than one outcome.
Sometimes the evidence confirms serious wrongdoing. Sometimes it leads somewhere entirely unexpected. And sometimes – one of the outcomes I find most satisfying – the investigation clears an employee who has been wrongly suspected.
The objective is not to obtain a confession. The objective is to establish the facts. Confessions can be extraordinarily valuable when wrongdoing has occurred, but they are a result of the process, not the purpose of it. An investigation that begins with the assumption that a particular employee is guilty has already introduced risk into the fact-finding process.
This is also why leadership should resist the temptation to believe that more activity necessarily produces more information. In the early stages of a sensitive matter, disciplined restraint can be more valuable than speed.
Before people begin asking substantive questions, leadership should understand what is alleged, how the information surfaced, who knows about it, what evidence may exist, and what has already been done. From there, the organization can determine the appropriate investigative strategy and the roles of Legal, Human Resources, Security, Compliance, management, internal investigators, or outside specialists.
Leadership does not relinquish responsibility when an investigation begins. Its role changes from informal fact gathering to ensuring that the organization has the right process, the right people, and the appropriate oversight to reach a fair and defensible conclusion.
The best investigations are not defined by how quickly someone begins asking questions. They are defined by whether the organization protected its ability to discover the truth before those questions were asked.
##Key Takeaways • A serious allegation does not require immediate informal questioning. • A preliminary assessment should clarify the allegation and guide next steps without becoming a pre-investigation. • Early disclosure of allegations or evidence can influence witnesses, alert subjects, and complicate later interviews. • Investigative interviews are specialized truth-seeking processes, not simply conversations with employees. • Leadership remains responsible for ensuring the right people, process, strategy, and oversight are in place.
