"He absolutely did not have the behavior of someone suicidal"

"I left without firm or absolute conviction on this affair," said the journalist first.

But very quickly, she said to have been able to refute a hypothesis: "Over the investigations, elements that I could find factually and over the testimonies that I collected, I realized that he had absolutely no behavior of someone suicidal. "

To forge this conviction, Anne-Sophie Martin analyzed a large number of documents written by the suspect, in particular during the years preceding the tragedy.

"Everything indicated that he had wanted to organize things (…) according to a method developed very cleverly."

"He was finally organizing an evaporation," she says.

Of course, the suicide thesis seemed possible to him at first.

But the fact that Xavier Dupont de Ligonnès was "not (yet) wanted" at the time of her disappearance and her "three week lead" over investigators in particular convinced her to the contrary.

"This is not the behavior of someone at the end of their rope and who is suicidal," she concludes.
