Tagelang the investigators in the near the place of residence and responded to the environment of missing – but the decisive turn brought a call on facebook. The fall of the 16-year isabella from the lower sachsian celle, which was held by some already dead and finally found well in france, made headlines nationwide. And he showed: criminal trap are also dissolved in the digital age in front of the computer screen.
Changed media consumption
"Public reliefs can be a valuable tool for investigations of any kind", says daniel kretzschmar, member of the executive board at the federation of german criminal officer. As an instrument for investigation, it has always been given. The social media and the internet are only other ways, which are also owed to a changed media consumption. "Where sooner the litfabsule looked at or a newspaper was read, as you can quickly look into the net today", says kretzschmar.
But what was in celle?? End marz disappears the 16-year-old schoolman isabella from her parents’ home. For weeks there is no sign of life, the police suspect a violent crime. A multi-divided facebook video call ends at the screen of a civil servant of the federal criminal police office (BKA). She recognizes the similarity with a madchen found in france and informs the colleagues in celle. Shortly thereafter, hope for certainty: the girl in france is isabella.
Rendering likes and postings
Investigation measures in social media play a great role in the declaration of crimes, as the berlin creditor toralf noding reports from his professional life. This not only applies to the declaration of crimes with internet reference, but also at "normal" crimes. For example, the facebook friends list of an accused will help to determine its contact persons. A look at persons who contribute to the accused "share" or "liqueur", could also provide insightful findings. Noding: "also posted images of the accused, on which he can be seen with certain, possibly tatrol-relevant clothes or allowing his whereabout to a certain (fact) time, can be interesting for the law enforcement behaviors."
Degree of study cybercriminalism
Free accessible data on the internet also play an important role in the daily investigation work for the police in north rhine-westphalia. "The analysis of digital data is an increasingly important aspect of the police work. Police NRW recognized the need to face this challenge and also develops new technical opportunities in this area", says the speaker of the ministry of the interior markus niesczery. Which concrete instruments use the investigators do not participate with niesczery from police-tactical reasons.
The police in hesse recently even sets a special degree program on the internet for a special degree program: since september 2020, police offspring can study cybercriminals there. This is to recruited particularly trained offspring and the digital competence is increased.
Openly accessible or hidden
But the police can easily access data from suspects in social media? "Material, which is publicly divided by the self-standing affected, can be evaluated by principle", so cruel. It becomes more difficult for hidden investigations, for example in protected chat groups and unemployments: here, a judicial decision is usually necessary.
Not always are suspicious in social networks with their clear names on the way. For their identification, the police often instructed that telecommunications companies store the internet connection data of their users over a long time. However, the data retention is highly conceivable. Only in october, the european court of justice decided that security authorizations in the EU such data are only stored in special exceptional cases – such as the acute threat of national security or to evaluate severe crimetat. Deutsche telekom stops the IP addresses of their users for seven days for seven days.
The freely accessible data treasure in the social networks helps investigators in the declaration of crimes. At the same time, however, he gives insights into habits and attitudes that would not tackle the state in a doubt. This at least holds the theoretical possibility that people alone could come to the focus of police investigations alone because of their attitude. "This danger is absolutely given", says noding. As particularly problematic, the lawyer sees, for example, when users through one "like" or "retweet" a contribution to the impression of a certain viewed inspection and the investigators constructed an initial suspected.
Kretzschmar stresses, however, that the responsibility of the police does not with the investigations on the internet end, the framework always form the law. "Therefore, I do not see a danger that the police beyond the statutory powers." nevertheless, in his opinion, everyone should consider exactly what information he has to do particularly – "from this, all people can win the same findings, like the police."
