An internal investigation is generally the first step to detect employee fraud. But it is not always easy. There are many missteps that can derail any investigation. The following show some of the most common missteps-and how to avoid them.
Investigative Team Bias
A risk manager's initial step is to determine who will be leading the investigation and who within the organization will be privy to the results. One commonly overlooked factor is whether the investigative team is sufficiently removed from the situation to assure independence. Before selecting an investigator, a company should examine the candidate's relationship with both the suspect and the whistleblower (e.g., the investigator should never be the suspect's supervisor) and also ensure that the candidate is at an appropriate level within the organization to obtain the required information.
Suspect Is Not Cut Off
Based on the severity of the potential fraud, the suspect may need to be immediately isolated and constrained from accessing potential evidence once fraud is detected to preserve the integrity of the evidence. Specifically, the suspect can be placed on a leave of absence and restricted from accessing the organization's internal computer network and its books and records during the course of the investigation.
Background Checks Are Limited
Background checks are a logical step during a fraud investigation but the search is often limited, resulting in missed information about the suspect's lifestyle or litigation history. Common mistakes include: limiting the background check to internet or search engine research; not conducting the criminal background check on local, state and federal levels (including civil court records); and not analyzing the data within the context of the fraud allegations being investigated.
Interviewing Suspect Too Early
Interviews are often one of the most valuable sources of information during an investigation. One common mistake is to interview the suspect of an investigation too early in the process, before investigators are able to review gathered documents and materials and interview other informants. Conducting the interview with the suspect later will enable investigators to develop pertinent questions and allow them to refer to relevant and potentially incriminating documents during the interview. Another mistake is to interview alone-two people should be present during an interview so that one can act as a witness and be responsible for documenting the findings.
