WE CONVICT ANONYMOUS OFFENDERS

Your company is attacked anonymously. You receive emails or letters in which you are threatened, maligned or blackmailed by an unknown person. We analyse the linguistic patterns of the texts to convict the offender.

WE CREATE CLARITY

  • OUR FIELDS OF APPLICATION

    You are being attacked anonymously via letters, emails and short messages e.g. constituting the following criminal offenses:

    • Blackmailing
    • Betrayal of corporate secrets
    • Industrial or economic espionage
    • Communication of confidential information
    • Menacing
    • Insult
    • Libel
    • Defamation
    • False accusation

    Our team of experts analyses the texts to find linguistic patterns for convicting the offender.

  • LINGUISTIC EXPERT OPINION

    You provide us with anonymous writings and text material of possible suspects. On this basis, we create a comparative linguistic expert opinion for determining the author. We analyse whether a suspect can be identified as the author or exonerated. Furthermore, we determine the degree of probability that a suspect is the offender.

  • OFFENDER PROFILES

    If no suspect or comparative text exists, we create an offender profile on the basis of the linguistic characteristics. This allows us to gather information about the following aspects:

    • Number of authors
    • Pretence in the text
    • Native language
    • Regional origin
    • Age group
    • Gender
    • Level of education
    • Profession
    • Text skills

    These aspects may provide important evidence for further investigation or exonerate suspects.

  • CRISIS MANAGEMENT

    Mistakes are often made at the beginning of an investigation, leading to high expenses afterwards. While anonymous offenses are an exception for you, they are business as usual for us. As our linguistic profilers work on identifying the offender, our crisis management team provides you with the necessary strategic counselling.

    Discrete and Confidental
    Your order will be treated with absolute discretion and confidentiality. In the case of a highly sensitive case, we pick up the data personally at your place and analyse the texts on computers with no connection to the internet. Upon request, our experts analyse the data at your company premises.

  • OUR CUSTOMERS

    We support:

    • Companies with a need for discrete investigations – without public prosecution
    • Law offices wanting to support evidence for their clients
    • State police offices in the context of investigations
    • Public prosecution for the preparation of court cases
    • Courts within the scope of examinations in criminal proceedings
    • Communities of heirs for examining the authenticity of last wills

Is a linguistic expert opinion usable in a court of law?

In the optimal case, the findings of our linguistic analysis are supported by further independent evidence. During the last 20 years, judgements in which the linguistic analysis was the only evidence became final at regular intervals. Among others, judgements from labour courts, district courts and state courts as well as at higher regional courts. Unequivocal results (as when analysing fingerprints or DNA) cannot be achieved by linguistic analysis. Under favourable circumstances, linguistic analysis allows for a very high precision when identifying an offender. A probability statement is part of each expert opinion

How long does it take to create a linguistic expert opinion?

This depends on the extent of the criminal writing as well as the comparative texts. Normally, we need about four weeks for an expert opinion which is usable at court. In the case of imminent danger, i.e. in the case of imminent severe crime, a „speed analysis“ is possible within eight hours.

Does the linguistic profiler need the original documents?

No. For the linguistic analysis, high-quality copies are sufficient. We prefer digital versions of the data.

Are linguistic expert opinions also possible for texts in other languages?

Principally yes. We are able to support you in English, French, Spanish and Italian.

Do you also analyse (hand)writing and voice?

For analysing handwritings and voice, we are able to recommend you first-class experts.
