20 minutes – That's what the DNA detects about criminals

In July 2015, a man loses a young woman from Emmen's bikes, and has lost her and lost her seriousness. Although more than 400 men were admitted to the DNA test, the trace did not yet feel. Currently, the police can only compare DNA profiles with a search database, but they cannot rate the content to obtain information about the appearance of a debtor. Bunders Karin Keller-Sutter wants to change that now, as it reports "Central Switzerland on Sunday".

Protecting Data Adrian Lobsiger speaks in a "Central Switzerland on Sunday" of a "sissical lack of our legal tradition", in order to remedy the right to prove it family.

Some traces of blood, muscle or semia are sufficient to determine the eyes, hair and skin color and the biogeographical origin in the laboratory. At a few years, it may also be possible to declare elevation, age, structure, or remorse of the affected person, says Cordula Haas, Institute of Legal Medicine Researcher in & # 39; a University of Zurich. "So you can say if someone has cold or curly hair."

Phantom image an "illusion"?

The prediction problem would be different: "Red or black hair, brown or blue eyes are relatively easy to recognize by DNA," says Haas. For brown hair or green eyes, the predisposition is already difficult, as well as other factors in addition to genetics.

In the United States, companies have already suggested that they make a fantasy image based on a DNA analysis. The complaints, however, are controversial. "The approach of companies is considered to be frivolous in professional circles," Haas said. "Creating a fantastic image of one's criminal by analyzing his DNA is – at least now – an illusion. Expectations are far too high. We are still far from all DNA fantasy images. "However, the future will be more and more possible.

But even then privacy would simply be guaranteed, says Haas. "We do not want the police information that & # 39; t even check it." As a police administrator, DNA phenotyping is a useful tool, says Haas. They advocate the possibility of using technology in serious crimes.

Police want new technology

Max Hofmann, Secretary General of the Swiss Police Commissioner (VSPB), confirms that a substantive DNA analysis would help the police. "Introducing such a technology would help us search people more efficiently and effectively."

Mass DNA testing would therefore not be necessary, the range of debtors would be limited. "The risk that a sex messenger or murderer could do even years, to" # ~ "would minimize the action."

General delay by DNA analysis

In contrast, the Swiss Data Protection Service, Adrian Lobsiger, serves against DNA analysis in terms of content. He describes in "Central Switzerland on Sunday" the theoretical case where it would be a rape in a village and DNA analysis would be a dark scrub. All men with dark skin were under general delays, Lobsiger said.

"Especially in a public search, prejudices wore in the least case to avoid spontaneous violence." In serious crimes against life and limb, but he has "some understanding" when DNA is being evaluated at & # 39; a basis of body identification.
