Blanche had a consistent modus operandi—when he spotted the victim, he would break into her house at night, bind her hands and bring her to his car, driving to the outskirts of the city, under the threat of a knife.
He was rearrested, and his second trial made it to the national headlines,[not verified in body] because the French police could not proceed with his arrest, since Blanche acted in several departments that did not share their judicial information.
[not verified in body] The national mediatization of the case lead to the creation of the automated judicial file for perpetrators of sexual offences.
On September 7, on Des Jardins Street in Caen, Blanche broke into the house of a woman named Nathalie at night, threatening her with tear gas and a knife.
On September 14, again on Des Jardins Street, Blanche broke into another woman's house, named Clara, at night, threatening her with a knife, tying her up and raping her.
[3][4][10] On June 21, in Reims, two students of a local school (12/13-year-old Aurore and an unnamed 17-year-old) ran away from class to attend a music festival.
After an interrogation, he was indicted in Charlville-Mézières, where Justice Paul-André Breton decided to place Blanche under judicial control, with no contact with his ex-wife, her daughter or the witnesses.
The warnings of the psychiatric experts, however, were not present on Blanche's profile, and despite the criminal record and the unfavorable opinion of the prosecutor, the judge decided that there was insufficient evidence, and Jean-Luc was released.
When they learned that it was Jean-Luc, gendarmerie realized several things, among them: he disrespected his judicial control; he hadn't shown up to work since July 13; he never went to his mother's house in Reims, nor did the weekly visit to the police station.
[10] On the night between August 25 and 26, between 4 and 5 p.m., on Des Jardins Street, Jean-Luc Blanche entered the studio of 19-year-old student Céline, which was on the first floor.
Instead of heading to the city center, Blanche drove to the countryside, parking on a small dirt road near Pont-l'Évêque.
He claimed to be a part of a network of human traffickers and must deliver her to his Russian or Turkish accomplices, so she could be prostituted in Eastern Europe.
They left by car, with Blanche stopping on several occasions, submitting his victim to psychological blackmail by pretending to hesitate, telling her that if he released her, he would lose his contract and certainly the confidence of his accomplices.
[3][13] On September 4, at around 4 p.m., in Saint-Loup-Géanges in Saône-et-Loire, Blanche entered the home of a 36-year-old real estate negotiator named Solange, whose husband had just gone to work.
The man chained Solange's arms in front of the fireplace, forced her to drink strong alcohol, undressed her and passed the blade of a knife along her body.
Blanche borrowed Solange's mobile phone to call her mother, so he could inform her that her daughter would be attending his birthday at his home in Reims.
On September 7, Jean-Luc Blanche was arrested at his mother's apartment building in Reims, where his concubine, Rachida, also lived.
[3] In his car, authorities found the string with which he tied the hands of his victims, along with audio cassettes and a CD player with Céline's voice recorded on them.
[6] Bruno attempt to make the court pity him, because he was in mourning: his concubine, Stéphanie Baudin, had been found dead at home on June 9.
His defense tried to mitigate the circumstances through the child abuse, during which Blanche received no love or care, with his ultra-violent farm worker father punished his children harshly.
