During his personality interrogation, Tuesday September 26, on the second day of the trial of the Magnanville attack (Yvelines), the accused, Mohamed Lamine Aberouz, developed with frank radicalism his conception of religion and living together. He felt that being ” French “ was a given ” ethnic “preferring to describe himself as a “Muslim of Arab origin”, and claimed that Islam was « incompatible » with democracy. But he knows it, it is not for his ideas that he is judged. “I will spare you from quoting Voltaire…”he even declared to the court.

If Mohamed Lamine Aberouz appears before the special assize court of Paris, it is because he is suspected of complicity in the assassination of a police officer, Jean-Baptiste Salvaing, and his companion, Jessica Schneider, killed on June 13, 2016 in their home in front of their three-year-old son. The charges against him were presented over three days by several investigators before concluding, Friday, September 29, with the heart of the case, the reason for which he was in the dock: his DNA.

While the investigative services initially focused on the theory of a solitary killer, Larossi Abballa, the connection between a trace of DNA isolated on the wrist rest of the victims’ computer and the profile genetics of the accused had finally led them to reconsider the course of events: according to the prosecution, Larossi Abballa, who was shot dead by the RAID, was accompanied in the couple’s pavilion by an accomplice, his friend Mohamed Lamine Aberouz, who would have managed to escape before the attack by the police.

“Skin strip”

This one and only trace of DNA is the crux of the trial. A Gordian knot, which each party strived to resolve in its favor by questioning two genetic experts. The first, Laurence Fournier, from the Paris Scientific Police Laboratory, carried out the first expertise which isolated the DNA trace of Mohamed Lamine Aberouz on the computer. The second, Olivier Pascal, director general of the French Institute of Genetic Prints, carried out a second opinion which did not make it possible to isolate the DNA of the accused.

For Laurence Fournier, there is no “no ambiguity” on the genetic profile found, the result of the second expertise being undoubtedly due to a “impoverishment of the trace”. As for the hypothesis of a transfer of DNA between Larossi Abballa’s car, where genetic traces of the accused were also isolated, and the victims’ computer, she argues that this DNA was « pur », and no “mixed” as would likely have been the case if it had been transported through a third party.
