Some investigations move quickly. Others take years. And sometimes, justice only begins to move when someone refuses to accept the first answer.
One powerful example is the case of Jean Hanlon, a Scottish mother of three who moved to Crete, Greece, in 2005. In March 2009, she disappeared after a night out. Her body was later recovered from the water at Heraklion Harbour. At first, authorities treated her death as an accidental drowning. But her family suspected something was wrong. A later post-mortem, requested after family intervention, concluded that she had been killed.
For years, the case remained unresolved. Charges were brought against two men during the first enquiry, but those charges were later dropped. The case went cold. According to STV News, the homicide case was reopened several times over the years, with the final investigation beginning in 2023.
That is where private investigation became important.
Jean’s family hired private investigator Haris Veramon. His work included compiling evidence, including information from Jean’s diary, which had reportedly been kept up to date until the day before she disappeared. That evidence related to a potential suspect and was handed to the Heraklion Prosecutor’s Office.
The case eventually moved forward. In 2026, a man who was known to Jean went on trial and was found guilty of her murder by a Greek court. STV News reported that he was sentenced to ten years in prison, although he remained free pending the appeal process under the Greek legal system.
What This Case Shows About Private Investigation
Private investigators do not replace police, prosecutors, or the courts. But they can play a valuable role when a matter needs a fresh review, careful organization, and persistent evidence gathering.
The Jean Hanlon case shows several lessons that apply to many investigations:
1. A Fresh Set of Eyes Can Matter
When a case has gone cold, it does not always mean there is no evidence. Sometimes, the evidence exists but has not been organized, connected, or presented clearly.
A private investigator can review timelines, documents, statements, digital clues, photographs, messages, public records, and prior reports to identify gaps or inconsistencies.
2. Personal Records Can Be Important
Jean’s diary became an important part of the case review. Diaries, messages, emails, calendars, photographs, receipts, travel records, and phone logs can sometimes help establish patterns, relationships, timelines, or concerns that were not obvious at the beginning.
In many investigations, small details become important only when they are placed in the right sequence.
3. Families Often Notice What Others Miss
Jean’s family did not accept the original explanation. Their persistence kept the matter alive. This is a reminder that family members, clients, and witnesses may hold valuable context.
A good investigation does not dismiss that context. It tests it against documents, timelines, records, and other verifiable information.
4. Documentation Is Everything
A private investigator’s work is most useful when it is properly documented. Information must be organized, sourced, and presented in a way that can be reviewed by lawyers, police, insurers, decision-makers, or courts.
Unverified rumours are not enough. Professional investigation requires careful notes, source tracking, lawful methods, and clear reporting.
5. Persistence Can Change the Direction of a Case
This case took 17 years to reach a conviction. That does not mean every cold case will be solved, but it does show why persistence matters.
Sometimes the difference is not one dramatic breakthrough. It is the slow, methodical work of collecting records, reviewing old evidence, building a timeline, and asking better questions.
The Takeaway
The Jean Hanlon case is a powerful example of why private investigation still matters.
In a world full of digital information, public records, social media, scattered documents, and incomplete timelines, the investigator’s role is to bring order to the facts. A professional private investigator looks for what can be verified, what is missing, and what needs further attention.
At The Investigators, we believe in evidence-led work, careful documentation, and clear reporting. Whether the matter involves online research, background checks, skip tracing, tenant issues, civil disputes, or case review support, the goal is the same: find the facts, organize them properly, and help the client make informed decisions.
Sometimes, the smallest detail can change the direction of an investigation.
