Threat Letters | Stalking | Anonymous Messages – Our Stuttgart Detectives Can Help

There are various psychological conditions and disorders that can cause individuals to develop obsessions with specific people, sometimes escalating to stalking or even exhibitionism. For the victims, such behaviour typically leads to severe emotional distress that can make normal life nearly impossible. Early intervention is therefore essential. The private investigators of Kurtz Investigations Stuttgart identify and expose the offenders: +49 711 7153 0028.

Threat letters and false orders – a common form of stalking

Our Stuttgart detectives frequently assist clients who are being terrorised with anonymous threat letters, insults, defamation, and harassment in the form of fraudulent product orders placed in their names. The list of potential criminal offences involved is long and can extend to bodily harm through psychological pressure.

Typically, the authors of such letters are not foolish – they take steps to avoid identification. Unfortunately, the police often fail to act, shifting responsibility between departments. In many cases, hiring a private investigator is the only effective course of action.

Handwriting analysis Stuttgart

Investigations involving threatening letters are often highly complex. However, the handwriting experts at Kurtz Investigations Stuttgart analyse such letters and prepare expert reports that can serve as evidence or a basis for further investigation. In some cases, even mantrailing (human-scent tracking) can be a useful complementary method.

Since there are sometimes misconceptions about handwriting comparison, it is important to note that a legally conclusive signature comparison is rarely possible when only two documents with single signatures are provided. For a fully court-admissible evaluation, approximately two A4 pages of comparable handwriting samples are needed. Also, handwriting experts should not be confused with graphologists, who claim to infer personality traits from handwriting—a method regarded as pseudoscience.

Stalking: calls, emails, texts, personal pursuit

Stalking can take many forms. Besides physical following, it often includes text messages, emails, late-night or early-morning phone calls, and threatening letters. These intrusions into the victim’s private life can seriously affect their sense of safety and quality of life. Anxiety, depression, and—in extreme cases—violence or sexual offences—can result.

Violent crime in Stuttgart – detectives identify offenders

While Stuttgart’s overall crime rate is comparatively low, the city unfortunately ranks among the highest in Germany for violent offences. In 2023, nearly 6,400 cases of bodily injury were officially recorded—significantly more than in Frankfurt am Main, often considered a high-crime city. Around 12,000 people became victims of violent acts. The reasons for this disproportionately high figure remain under debate, and as long as experts disagree on the causes, no effective strategy to address the issue can be implemented.

One theory proposed by Kurtz Investigations Stuttgart suggests that Stuttgart’s much-celebrated integration of its large immigrant communities has not been as successful as presented in the media. The proportion of under-21s involved in violent offences is exceptionally high, and among young people, the percentage of those with an immigrant background is markedly greater than in older age groups. It is statistically proven that immigrants in Baden-Württemberg still face fewer educational and employment opportunities, leaving them more vulnerable to poverty than native Swabians. The causal link seems evident: Stuttgart’s high rate of youth violence may be rooted in the large number of young migrants with limited prospects—many of whom turn to street life. Despite official optimism, the city’s integration policies clearly have room for improvement.
