Detective Murders – Private Homicide Investigations in Greece

ντετέκτιβ δολοφονίες detective murders

Detective Murders investigations involve some of the most complex and sensitive work undertaken by private investigators. At Nikos Pelekasis & Associates, we provide independent investigative support in homicide, suspicious death and serious criminal cases in Athens, Piraeus and throughout Greece.

With more than 30 years of experience in private investigations, our agency can assist families, lawyers and other legitimately interested parties by reviewing available evidence, identifying potential investigative leads and conducting lawful supplementary investigation.

A private investigator does not replace the Hellenic Police, prosecutors, forensic authorities or the courts in a homicide investigation. Criminal investigation and prosecution remain the responsibility of the competent authorities.

Our role is different: to independently examine information and evidence available to the client, investigate legitimate unanswered questions and provide additional investigative support where appropriate.

Detective Murders and Private Homicide Investigations

A homicide investigation can involve a large amount of information from many different sources.

Witness statements, photographs, CCTV footage, digital devices, timelines, telephone information lawfully available to the client, forensic findings and other evidence may all need to be considered together.

In some cases, families contact a private investigator because they believe important questions remain unanswered.

In others, a lawyer may require additional investigation concerning a specific factual issue relevant to an ongoing or completed case.

Our work may include:

  • Independent review of available evidence
  • Reconstruction of relevant timelines
  • Identification of inconsistencies or unanswered questions
  • Witness identification and lawful information gathering
  • CCTV and video review
  • Open-source intelligence
  • Digital evidence examination
  • Investigation of locations and movements
  • Background research
  • Review of existing documentation
  • Coordination with lawyers and specialist experts
  • Investigation of new leads
  • Preparation of investigative reports

The methodology is determined individually according to the circumstances of each case.

Independent Review of a Homicide Case

One of the most valuable roles of a private investigator in a serious criminal case can be providing an independent review of the information already available.

A fresh examination does not mean that the original investigation was necessarily incorrect or incomplete.

However, complex cases can contain hundreds or thousands of individual pieces of information. Reviewing them from a different investigative perspective may identify details requiring further examination.

Depending on the material lawfully available, an independent review may consider:

  • Existing reports
  • Photographs
  • Video footage
  • Timelines
  • Witness information
  • Digital evidence
  • Publicly available information
  • Locations relevant to the case
  • Known relationships between individuals
  • Previous investigative findings

The objective is to identify factual questions that can legitimately be investigated further.

Suspicious Death Investigations

Not every case begins with a confirmed homicide.

A family may have concerns regarding the circumstances surrounding a death and seek an independent examination of available information.

Questions may involve:

  • The timeline before the death
  • Individuals present or involved
  • Conflicting accounts of events
  • Unexplained communications
  • Relevant CCTV footage
  • Digital information
  • Circumstances surrounding the location
  • Other inconsistencies requiring clarification

A private investigator cannot independently determine the official cause or manner of death.

Medical and forensic conclusions must be made by the appropriately qualified medical, forensic and judicial authorities.

However, an investigator may examine surrounding circumstances and identify information that could be relevant to the client’s lawyer or competent authorities.

Cold Case Investigation and Unresolved Homicides

Cases that remain unresolved for years can present particular difficulties.

Memories fade, individuals relocate, physical locations change and some records may become more difficult to obtain.

At the same time, new information or technological developments can sometimes justify reviewing older material.

A private cold case investigation may involve:

  • Re-examining existing evidence
  • Reconstructing the original timeline
  • Locating individuals connected with the case
  • Identifying witnesses who may still be available
  • Reviewing old photographs and recordings
  • Examining publicly available information
  • Evaluating new leads
  • Reviewing digital material where available
  • Comparing information from different sources

No responsible investigator can guarantee that an unresolved homicide will be solved.

The purpose of a cold-case review is to determine whether new, overlooked or previously unavailable investigative leads can legitimately be developed.

Witness Identification and Location

Witnesses can be extremely important in serious criminal investigations.

Over time, however, witnesses may move, change telephone numbers or become difficult to locate.

Professional tracing methods may assist in identifying or locating individuals who may have information relevant to the investigation.

Depending on the circumstances, useful starting information may include:

  • Full name
  • Previous address
  • Telephone information
  • Employment
  • Approximate age
  • Known associates
  • Previous connection with the location or individuals involved

Any contact with potential witnesses must be handled carefully.

A private investigator does not have police powers and cannot compel a person to provide information or a statement.

Witness Information and Interviews

Where appropriate and lawful, interviews or voluntary conversations may help clarify facts or identify new investigative leads.

The objective is to obtain information without influencing or pressuring the individual.

Particular care is necessary where the person may already have provided an official statement to the authorities.

Private investigative activity should never interfere with an active police or judicial investigation.

If significant new information concerning a serious crime is identified, the appropriate course of action may involve the client’s lawyer and the competent authorities.

CCTV and Video Evidence

Video footage can provide important information in homicide and suspicious-death investigations.

Depending on the material lawfully available, analysis may help establish:

  • Individuals entering or leaving a location
  • Vehicle movements
  • Direction of travel
  • Relevant times
  • Clothing or identifying characteristics
  • Sequences of events
  • Activity before or after an incident
  • Connections between different camera locations

Where recordings from several cameras exist, creating a chronological sequence can help reconstruct relevant movements.

The usefulness of CCTV evidence depends heavily on image quality, camera position, timestamps and preservation of the original recordings.

Photographic Evidence

Photographs can also contain details that were not immediately considered significant.

Depending on the circumstances, examination may focus on:

  • Objects visible within a scene
  • Position of relevant items
  • Vehicles
  • Clothing
  • Environmental details
  • Timestamps and metadata where legitimately available
  • Differences between multiple photographs
  • Other visual information relevant to the timeline

Photographic material should be evaluated together with other available evidence rather than interpreted in isolation.

Digital Forensics in Homicide Investigations

Modern serious criminal investigations frequently involve digital evidence.

Smartphones, computers, storage devices and other electronic systems may contain information relevant to establishing events, communications or timelines.

Where lawful authority exists to examine a device or data, Digital Forensics may assist in identifying and documenting relevant electronic evidence.

Depending on the circumstances, forensic examination may involve:

  • Files and documents
  • Photographs and videos
  • Available metadata
  • Device information
  • Relevant system activity
  • Digital traces
  • Recoverable deleted information
  • Other technically accessible evidence

Recovery of deleted information cannot be guaranteed. Modern encryption and subsequent use of a device can significantly affect what remains technically recoverable.

Preservation of Digital Evidence

Preservation is particularly important in serious investigations.

Continued use of a smartphone or computer can modify data. Installing applications, deleting files, performing updates or resetting a device may alter potentially relevant evidence.

If a device may contain important information, unnecessary changes should generally be avoided until an appropriate forensic strategy has been considered.

Where technically appropriate, forensic methodology aims to preserve original information and document the examination process.

Where a smartphone may also have been compromised or subjected to unauthorized surveillance, a separate Mobile Spyware Detection examination may be appropriate.

Mobile Phones and Communications

Mobile phones can contain significant information relevant to reconstructing events.

However, a private investigator does not have unrestricted access to another person’s:

  • Telephone calls
  • SMS messages
  • WhatsApp conversations
  • Email accounts
  • Cloud accounts
  • Location history
  • Telecommunications records

Access depends on lawful authority, ownership, consent and the circumstances of the case.

Information held exclusively by telecommunications companies or online platforms may require formal requests by the competent authorities or appropriate judicial procedures.

We do not provide unauthorised access to private communications or accounts.

Open-Source Intelligence in Homicide Cases

Open-Source Intelligence (OSINT) can sometimes provide additional context to a serious criminal investigation.

Lawfully accessible sources may include:

  • Public social-media profiles
  • Websites
  • News archives
  • Public corporate information
  • Publications
  • Professional information
  • Public photographs and videos
  • Other openly available online material

OSINT research requires careful verification.

Online information may be inaccurate, outdated, deliberately misleading or associated with the wrong individual.

For this reason, information should be cross-checked before being treated as relevant to an investigation.

Social Media Investigation

Social media can provide information concerning relationships, activities, locations or connections between individuals.

Depending on privacy settings and lawful accessibility, publicly available material may assist in developing investigative leads.

Research may examine:

  • Public profiles
  • Public posts
  • Public photographs
  • Usernames and aliases
  • Connections visible publicly
  • Relevant historical content

Private investigators cannot compel social-media platforms to disclose private account information.

Such records generally require the appropriate legal or judicial process.

Timeline Reconstruction

Establishing an accurate timeline is often fundamental in a homicide or suspicious-death investigation.

Information from different sources may need to be compared to determine what happened before, during and after a critical event.

A timeline may combine information from:

  • Witness accounts
  • CCTV footage
  • Photographs
  • Documents
  • Digital evidence
  • Publicly available information
  • Known movements
  • Other lawfully obtained investigative findings

Even relatively small differences in timing can sometimes reveal inconsistencies requiring further investigation.

Location and Movement Analysis

Understanding where relevant individuals were at particular times can be important.

This may involve comparing lawfully available information from multiple sources, such as CCTV footage, witness observations, documented movements and other evidence.

A private investigator does not have unrestricted access to live mobile-phone location information or telecommunications location records.

Where protected location information is required, access must occur through the appropriate lawful process.

Collection and Review of Evidence

A serious investigation may involve a considerable amount of material.

Our Collection of Evidence methodology focuses not simply on accumulating information, but on identifying, evaluating and documenting material that is genuinely relevant to the investigative objective.

Depending on the case, this may involve:

  • Photographic evidence
  • Video material
  • Digital evidence
  • Documents
  • Investigative observations
  • Open-source information
  • Timelines
  • Witness information
  • Other lawfully obtained findings

Information is evaluated in context and compared with other available evidence before conclusions are drawn.

DNA and Forensic Laboratory Evidence

DNA and other biological evidence can play a major role in criminal investigations.

However, DNA analysis is a specialised scientific discipline and should be performed by appropriately qualified forensic laboratories and experts.

Where biological material is relevant to a privately instructed investigation, the circumstances of its origin, lawful possession, preservation and chain of custody must be carefully considered.

Our role may involve coordinating investigative information with appropriate specialist professionals where necessary.

We do not present private investigative assessment as a substitute for official forensic laboratory analysis.

Forensic and Specialist Experts

Some cases require expertise beyond the scope of a private investigator.

Depending on the circumstances, appropriate specialists may include:

  • Forensic pathologists
  • Digital forensic specialists
  • DNA laboratories
  • Technical experts
  • Lawyers
  • Other appropriately qualified professionals

A multidisciplinary approach can be valuable when the investigation involves complex scientific, technical or legal questions.

Each specialist should remain within their professional field of expertise.

Cooperation With Lawyers

Lawyers frequently play an important role when a private homicide investigation is undertaken.

They can help define the legal objective, determine what information may be relevant to proceedings and advise the client regarding how new findings should be handled.

Where appropriate, our investigative work can be coordinated with the client’s legal representatives.

This is particularly important when:

  • Criminal proceedings remain active
  • New evidence may need to be submitted
  • A case is being reconsidered
  • Expert evidence is required
  • Legal admissibility is an important consideration

Cooperation With the Authorities

A private investigation must never obstruct or interfere with an official criminal investigation. Serious criminal offences and information concerning potential criminal activity should be reported to the appropriate authorities, including the Hellenic Police.

Where significant information concerning a homicide or other serious crime is identified, the appropriate authorities may need to be informed.

Depending on the circumstances, this can be handled in coordination with the client’s lawyer.

Private investigators do not possess the investigative powers of police or prosecutors.

We cannot issue warrants, compel testimony, demand protected telecommunications data or perform other actions reserved for public authorities.

Investigation Reports

Depending on the assignment, findings can be organised into a professional written investigation report.

The report may contain:

  • Scope and objective of the investigation
  • Information initially provided
  • Investigative methodology
  • Relevant factual findings
  • Timelines
  • Photographic or video material
  • Digital findings
  • Open-source findings
  • Identified inconsistencies
  • Supporting documentation

The report should distinguish clearly between verified information, investigative observations and conclusions or hypotheses.

Legal Limits of a Private Homicide Investigation

Private investigators operate within the law and do not possess police powers.

A private homicide investigation does not permit:

  • Illegal interception of communications
  • Unauthorised access to private accounts
  • Hacking
  • Unlawful GPS tracking
  • Access to protected police databases
  • Unauthorised access to telecommunications records
  • Coercive interrogation
  • Entry into private property without lawful authority
  • Interference with evidence held by authorities

Investigative methods are assessed according to the circumstances and applicable legal framework.

The seriousness of an allegation does not remove legal restrictions on how evidence can be obtained.

Confidentiality in Serious Criminal Investigations

Homicide and suspicious-death cases frequently involve extremely sensitive information.

Confidentiality is therefore essential.

Information concerning the client, investigation, witnesses and findings is handled discreetly.

Communication arrangements can be established before the investigation begins, particularly where the case involves ongoing legal proceedings or significant media attention.

Cases With Media Attention

Some homicide cases receive extensive coverage in newspapers, television and online media.

Media reports can provide useful background information, but they should not automatically be treated as established fact.

Published information may be incomplete, based on early reports or contain speculation.

Our investigative approach distinguishes between:

  • Officially established information
  • Evidence available for examination
  • Verified investigative findings
  • Media reporting
  • Unverified allegations
  • Speculation

Maintaining this distinction is particularly important in high-profile cases.
