Delegated lecture on the importance of genetic criminal investigation – Region
The specialist in genetic criminal investigation, delegate of Estância Velha and professor of regulation at Faccat, Rafael Sauthier, has stood out at nationwide degree with a lecture on the importance of bettering a nationwide database of deoxyribonucleic acid (DNA), built-in between the states. to resolve crimes.
He is the creator of the e-book Identification and genetic criminal investigation, revealed in 2015. The use of DNA is a expertise adopted worldwide and in Brazil it has been utilized by the authorities, by means of the civil and federal police and the Department of Criminalistics , since 2012.
In lectures and occasions the place Rafael talks about the topic, he emphasizes that by means of DNA it’s attainable to resolve crimes sooner. “With the genetic profile of these questioned samples from the crime scene, it’s positioned in a database the place there are already genetic profiles of a number of people. The laptop makes the comparability, and if the genetic profile of the crime scene matches the genetic profile of one of these people, it’s stated that there was a “match.” And this particular person is positioned at the scene of the crime, which serves as criminal proof,” the delegate explains.
According to Sauthier, the work is finished by amassing organic samples at the crime scene, resembling blood, saliva, nails, cells, human tissue, items of pores and skin, semen, amongst others. “From these samples, that are referred to as interrogated, a technical process referred to as genetic typing is carried out, by means of which the genetic profile of the one that left these samples at the crime scene is extracted from the samples. The genetic profile is sort of a genetic fingerprint”, says the delegate .
In addition to the e-book, Sauthier’s work is an in-depth educational examine on the topic, which is a pioneer in the nation and has been cited in time period papers, dissertations and theses. “It is maybe one of the most in-depth and precursor books on the topic in the nation and in Portuguese”, says the delegate, who emphasizes that the central thought of the work he has developed is to encourage and proclaim the importance of to have genetic samples from all prisoners from Brazil to check them with supplies collected at crime scenes.
“It’s a topic that includes molecular biology ideas, the complete writing course of, criminal identification. I attempt to clarify it in a method that individuals who haven’t got this technical information can perceive. In one other second, I take experiences from different nations and make a comparability. Then I remark on the regulation, and in the finish I do the complete strategy, the elementary rights concerned, the way to resolve this”, summarizes delegates.
Appearance at police stations
The use of DNA already exists in Brazil and has already reached the police stations. According to the delegate, the police stations demand this kind of experience and the Crime Branch, which has geared up and skilled personnel, is the one who carries out the experience and prepares the stories that are linked to investigations and trials and act as criminal proof. “The police stations solely request the experience of the Criminal Investigation Department, which is the one who carries out the experience, collects organic samples at the scene of the crime or from reference individuals, carries out the genetic typing process, makes the stories, inserts the genetic profiles into the database genetic profiles for criminal functions”, emphasizes Sauthier.
