In 2016, I ran an investigation support program for one of the financial institutions. After the fraud investigations, from inception to disposition, training, Summit Consulting Ltd was retained to support the inhouse investigations team with case management work for on job training where we would work closely with the internal team to guide their investigations from inception, case strategy (fraud hypothesis and testing), statement taking, field investigations, digital evidence, and chain of custody, dealing with police officers and other agencies, etc. It was a great experience.
The fraud investigation team occupied the smallest office on the floor. It had no fancy branding, no applause at staff town halls, and very few visitors except when something had gone terribly wrong. The people inside that office lived with an unusual burden. They were expected to uncover the truth in environments where people concealed it, protect the institution while remaining independent, and gather evidence strong enough to withstand scrutiny from senior management, lawyers, regulators, and courts. Yet the greatest challenge they faced was not technology, nor sophisticated fraudsters, but loneliness.
I remember a case where I was invited to investigate a matter at a large institution after rumours began circulating quietly through corridors. The organisation was performing well, revenue targets had been achieved, the board was satisfied, and the executive team was confident. Then small anomalies began appearing. Supplier payments that looked ordinary at first glance started raising questions; a few invoices had similar descriptions but slightly different vendors; some approvals happened unusually fast, and a supplier that had never existed a few years earlier was suddenly receiving significant contracts.
The internal investigations unit noticed the pattern, but the challenge was that nobody wanted to believe it. The head of investigations, a reserved gentleman with greying hair and sharp eyes, had raised concerns before. This time, however, the issue touched influential individuals. Suddenly the investigators found themselves isolated; people avoided them in corridors, requests for documents slowed down, witnesses became hesitant, and every question they asked was interpreted as an accusation.
This is the lonely reality of internal investigations. Investigators are expected to protect the organisation, but they often become unpopular when they do. The irony is painful. An organisation readily celebrates the sales team for bringing money in. It praises operations for efficiency, rewards innovation, but the investigators who quietly prevent losses, recover stolen assets and expose control failures often work in silence. It is like how the defenders who work hard to prevent conceding goals never get celebrated like those who score. A shepherd dog rarely receives applause while guarding sheep. It only gets attention when a wolf enters the flock. That is the life of an internal investigations team.
How fraud hides behind normal business
The investigation began with data. Most investigators start by interviewing people, but top investigators start by understanding systems. We obtained payment records, procurement logs, approval workflows, emails and access logs. The fraud did not reveal itself immediately as everything appeared legitimate.
That is precisely how sophisticated fraud works. Fraudsters rarely create transactions that look suspicious. They create transactions that look ordinary. The suppliers had valid registration documents, contracts existed, approvals were properly signed, payments supported by invoices, and the control environment appeared functional.
But forensic work is not about examining what is present; it is about noticing what should have been present but is absent. The investigators noticed that supplier onboarding documents contained unusual similarities, phone numbers overlapped, email recovery accounts pointed to related individuals, IP addresses used during supplier registration appeared linked, the timing of approvals was remarkably consistent, and several contracts were approved shortly after budget reallocations.
Tiny details destroy large lies. A forged signature may escape attention, a manipulated invoice may appear convincing. But digital footprints are stubborn witnesses. Technology remembers but people forget.
How investigators become isolated. The most difficult stage of any investigation is not collecting evidence, it is managing relationships. As suspicions grew stronger, pressure began mounting on the investigations team. Why are you investigating this supplier? Why are you asking about this executive? Are you certain your conclusions are correct? Could there be another explanation? Those questions are reasonable.
Good investigators welcome scepticism but organised resistance feels different. Documents disappear, emails are deleted, witnesses suddenly forget, people become defensive, and some executives begin treating investigators as adversaries rather than protectors. This creates emotional isolation.
Investigators cannot openly discuss their suspicions, they must remain objective. They carry confidential information and see the darker side of human behaviour more frequently than most professionals. The psychological burden is immense.
An executive once told me something I never forgot. “When people see us entering a room, conversations stop. Yet when the organisation suffers losses, everyone asks where the investigator was.” That statement captures the paradox perfectly. The better investigators perform, the more worried they make dishonest people.
Why ExCo matters more than it thinks
The executive committee shapes the success or failure of internal investigations more than any technology. An unsupported investigations team becomes reactive while a trusted investigations team becomes transformational.
ExCo must provide four things.
- Investigators should never fear consequences for pursuing facts.
- Digital investigations require specialised software, forensic expertise and continuous training.
Tone from the top.
Employees must understand that investigations protect the institution rather than target individuals. Investigators often uncover tough truths hence, they need assurance that integrity will be rewarded rather than punished. An organisation that weakens investigations weakens itself. A castle does not become safer by dismissing the guards.
How digital evidence changed the case
The turning point came unexpectedly. One investigator requested access to historical system logs, not summaries nor raw logs. The records showed unusual access patterns. A procurement officer’s account accessed supplier records outside normal working hours, changes were made shortly before approvals, several supplier details were edited repeatedly, and the logs were preserved carefully.
This is where many investigations fail. Investigators focus on discovering evidence. Elite investigators focus equally on preserving it. Every action was documented, original files remained untouched, hash values were calculated, access records were maintained, and chain of custody was preserved meticulously.
Digital evidence behaves differently from physical evidence. A paper document deteriorates naturally while digital evidence can disappear instantly or worse, it can be challenged in court if investigators cannot prove authenticity.
This is why courts increasingly examine not just what evidence exists but how it was collected, preserved and analysed. The method matters. The smallest mistake can create doubt, and doubt is fertile ground for defence counsel.
Anticipating the defence
Experienced investigators think like defence lawyers before litigation begins.
Could another employee have used this account?
- Were timestamps synchronised?
- Was the evidence altered?
- Were forensic images created properly?
- Who had access to the servers?
- Was there lawful authority to collect emails?
These questions are difficult to answer. Investigations are not exercises in suspicion but exercises in proof. Proof demands discipline. This is where many organisations underestimate internal investigations. They see investigations as an operational activity, yet courts see investigations as evidence creation. There is a profound difference. And organisations that appreciate that distinction protect themselves far better. The emotional cost investigators rarely discuss, the hardest cases are not the technically complex ones, the hardest cases involve people investigators know, respect or once trusted.
The short lady in the investigations team, quiet but exceptionally observant, once told me that. “We do not investigate strangers but relationships.” That sentence explains why investigators often feel isolated. They must remain impartial when others take sides, pursue facts when rumours dominate, remain calm when emotions run high and live in a world where trust is constantly tested, yet they continue because institutions need truth, but even when truth is not easy to take in.
What the future demands
Artificial intelligence is changing fraud. Synthetic identities are emerging, deepfake audio can imitate executives convincingly, and automated attacks can manipulate internal processes at scale.
Fraudsters increasingly exploit human trust rather than technical weaknesses. This means investigations teams must evolve. Future investigators will need legal skills. Behavioural analysis, cybersecurity expertise, data analytics, digital forensics and artificial intelligence literacy.
The investigator of tomorrow is not simply an interviewer. They are part lawyer, part technologist, part psychologist, and part strategist. ExCo must invest accordingly because when fraud becomes more intelligent, investigations must become wiser.
The final lesson
The lonely life of an internal investigations team is not inevitable.
Executives can change it.
- By protecting independence.
- By funding capabilities.
- By celebrating integrity.
- By treating investigators as strategic partners.
Because the best investigations teams do not merely expose fraud. They prevent it, strengthen culture, and protect reputation. They quietly save organisations from crises that never make headlines. And perhaps that is their greatest challenge.
Their finest victories are often invisible, yet without them, many institutions would discover too late that the greatest risk was never the fraudster outside. It was failing to support the people inside who were trying to protect them all along.
