The trial, at the Vannes Assize Court, of Guillaume Lieury, accused of the murder of Guillaume Bertincourt, on November 12, 2021, in Lanester (56), will close on Friday. A few hours before the verdict, many questions still linger. “I feel like there are lies everywhere. I think that I will never have the truth,” said the victim’s sister. A “generous, hard-working, very sociable” brother, she describes him. “A guy with a heart of gold, always on time, clean on himself,” reports the owner of the Quiberon restaurants in which he worked.
Since the beginning of the debates, doubt has hovered over the murder weapon: who did this Opinel-type knife belong to? Where did he go? Guillaume Lieury always said that it belonged to the victim but changed his version several times about how it ended up in his hands. “The knife has fallen,” he said at the start of his hearings. Then Guillaume Bertincourt would have thrown it behind his back, he finally revealed during the reconstruction, in August 2023.
A brother who accuses himself out of fraternal spirit
Guillaume Lieury's brother, present with him on the evening of the murder, initially accused himself to the investigators, “out of a fraternal spirit”. He had said that the knife had fallen from Guillaume Bertincourt's pocket and now assures that he only discovered the presence of a knife and that a blow had been given when the two brothers were hidden behind a store.
What was Guillaume Lieury's state of mind when he arrived at Lanester's meeting? He assures that he thought he would get the money back, did not expect a fight but threatened the victim by SMS several weeks before the murder. The accused had consumed “ten beers and ten rails of cocaine” during the day. “He was in his normal state,” said his brother. They returned to the latter's house and acted “as if nothing had happened”.
At a nightclub the day after the murder
The next day, they even went to the nightclub where the victim's sister worked. “To party”, asks the president of the Assize Court? “To see Guillaume Bertincourt’s sister but she wasn’t there. A bouncer told me what happened to his brother. I didn't have time to report myself, the police arrived and took me away. »
The accused was pushed around a little this Thursday by the president of the court, by the lawyer for the civil parties and by their emotion. He begins to talk about going out, he who is not able to manage the administration and who was still sending his laundry to his mother. He says he wants to find out about guardianship, wants to escape nightclubs, stay with family, would like to get his job back. He will be sentenced on Friday November 22.
