The Strasbourg prosecutor's office on Monday requested the referral for the assassination of Jean-Marc Reiser to the Bas-Rhin Assize Court.
He admitted to having killed the Strasbourg student Sophie Le Tan in September 2018.
"A partial dismissal for the facts of kidnapping and forcible confinement was also required," added Laurent Guy, deputy prosecutor of Strasbourg, in a press release.
The young woman had not given any sign of life after going to Schiltigheim, north of Strasbourg, to visit an apartment which Jean-Marc Reiser, 60, had posted an ad online. He quickly became the sole suspect in this case.
In February, a reconstruction was organized in the former studio of Jean-Marc Reiser, in Schiltigheim, almost a month after his confession, on January 19.
He had described a "business of seduction" which "went wrong", according to the words of his lawyer, Me Pierre Giuriato.
While the young woman of 20 years had "rejected" his advances, he had "entered a phase of frustration, anger, rage", which had "materialized by violent blows".
For the lawyer, the confessions of his client are part of "willful violence resulting in death without intention of giving it", facts less severely punished criminally than murder, which involves premeditation.
