Jacques Rançon is a Frenchman who has been convicted of three killings, committed eleven years apart in two parts of the country. Moktaria Chaïb, 19, was killed in Perpignan in December 1997, and Marie-Hélène Gonzalez, 22, in the same city in June 1998. Isabelle Mesnage, 20, was killed near Amiens, in his native Picardy, in July 1986. He was tried for the Perpignan killings in March 2018 and for the Picardy killing in 2021, with a second trial on appeal in June 2022. He has been sentenced to life imprisonment twice.
The Perpignan inquiry ran for 17 years without an arrest. It ended in October 2014 when a partial DNA profile from the 1997 case, analyzed years earlier, matched a man who had entered the national fingerprint file for an unrelated offense. The Picardy case, closed without charges in 1992, was reopened in 2017 after the family's lawyers followed the Perpignan trial and saw a connection. The two sets of proceedings are linked by the same man, and by families who waited decades for a court to name who was responsible.
Rançon was born in Hailles, a village of about 500 people in the Somme, in Picardy. He was 54 when he was arrested in October 2014. Europe 1 and Le JDD both described him as originally from Picardy, and Le JDD reported that he moved to the Perpignan area in 1997.
His childhood is known mostly from witnesses at the Perpignan trial. His half-sister, the only sibling who kept in touch with him, told the court by video link from northern France that their father had been very cruel and the childhood chaotic. A teacher who taught him in Hailles from September 1970, when he was ten, described a shy, left-handed boy who was two years behind others of his age. According to that teacher, the family lived in a wooden shack on the edge of the village, the father did manual work, and the mother had other children placed in care by the child welfare service. Food vouchers for the boy passed through the town hall. The teacher told the court that he had learned of the crimes four years earlier and felt partly responsible for not having done more at the time. The defense had no questions for him.
Rançon later worked as a forklift operator and warehouse hand, mostly in temporary jobs. In the early 1990s he was living in the Amiens area, where a former partner and the mother of his eldest son also lived.
In 1992, at the age of about 32, Rançon was involved in an offense against a young woman in Picardy for which he was arrested and held in pretrial detention. In January 1994 the Somme assize court convicted him of rape and sentenced him to eight years in prison. Europe 1 reported that he served five of those years and that he moved south in September 1997, shortly after leaving the Amiens prison.
In October 2013 he was sentenced to one year in prison for threatening his former partner, the mother of two of his children. He served nine months and was released in July 2014. The 2013 case mattered for a technical reason: his profile was entered in the national genetic fingerprint file, known as FNAEG, in connection with it.
Europe 1 reported that in September 1997, shortly after leaving the Amiens prison, he moved to Perpignan and stayed in hotels. Le JDD described him in 2014 as unemployed and without a permanent home.
The Perpignan killings took place within a few months of his arrival. For 17 years the inquiry that followed produced no charge against anyone for these two killings.
Moktaria Chaïb was 19 when she was killed in December 1997. After the verdict in March 2018 her brother left the courtroom together with a sister of Marie-Hélène Gonzalez.
Marie-Hélène Gonzalez was 22 when she was killed in June 1998. Her mother was present at the trial, and left the court with the two investigators who had worked on the case, Vincent Delbreilh and Guy Armand, after the verdict. Two of her brothers were in the courtroom on March 14, 2018, and what happened that day is described below.
Little has been made public about either woman's life outside the case. The lawyer for the families at trial, Nicolau, said that the life sentence the jury was about to impose could not match the sentence the families themselves had carried since the deaths. In the closing stage of the trial the court heard that the families had lost ordinary occasions such as Christmas and birthdays.
Two other young women survived. In the case of one, in 1998, Rançon was charged with attempted murder in her case, and in June 2015 he admitted the attack. The other, referred to in court under a pseudonym, was the target of an attempted rape for which he was also tried.
Police did not at first treat the cases as the work of one man. False leads took up months. A man was held for several months in 1998 and then released, and other men were examined and set aside.
Investigators also compiled a long list of men to interview. Le JDD reported that Rançon was one of about 100 suspects questioned in the years after the killings, and Europe 1 reported that he was among hundreds questioned in September 1998. L'Indépendant, as quoted by Europe 1, said that his home was searched at the time. He was not singled out, and the analyses of that period produced nothing.
The breakthrough came from scientific work that took years. A partial genetic profile had been recovered from one of Moktaria Chaïb's belongings, and it was analyzed in 2010. No match came up until the national file received Rançon's profile after the 2013 case involving his former partner. According to Europe 1, the match was made on October 10, 2014, and identified a man already convicted of rape. It came 17 years after the killing.
Le JDD reported that Rançon was arrested on Tuesday around midday, October 14, 2014, in Perpignan and held in police custody that week. Prosecutor Achille Kiriakides said that the suspect's identity had been known to investigators since the previous week. He denied any link to the Perpignan cases at first. Between Wednesday and Thursday he confessed to the rape and murder of Moktaria Chaïb.
The prosecutor said he did not appear to have acted with an accomplice. On Thursday, October 16, 2014, he was presented to an investigating judge and placed under formal investigation. The charges were rape as a repeat offender and murder, for which the maximum is life imprisonment. At that stage he denied any part in the death of Marie-Hélène Gonzalez.
The confession did not hold. In March 2015 he retracted, saying that investigators had put pressure on him. Sud Radio reported on June 9, 2015 that he had changed course again. Taken into custody on the Monday afternoon at the regional police headquarters in Perpignan, and held beyond the first period, he volunteered overnight between Monday and Tuesday that he had killed Marie-Hélène Gonzalez. The week before, he had admitted the 1998 attack on the young woman who survived.
Rançon was held at the prison in Béziers. According to Slate, he was kept in isolation there at his lawyers' request, because they feared for his safety, and he received no visitors. Several psychiatrists who examined him reported that he had had a psychotic episode in detention. They attributed it to confinement and not to mental illness. His lawyers had expected him to say nothing at trial.
The trial opened on Monday, March 5, 2018, before the Pyrenees-Orientales assize court in Perpignan, with Rançon, then 58, in the dock. Sud Radio called it an exceptional trial for the city. It was expected to last three weeks. About ninety journalists were accredited and more than forty witnesses and experts had been summoned from across France, according to Slate, and security at the courthouse was reinforced. The presiding judge was Régis Cayrol. Six jurors, four men and two women, were drawn by lot to sit alongside the professional judges.
The charges covered two murders accompanied by rape, the attempted murder of a young woman who survived, and the attempted rape of another. On the first day the president read out the accusations and Rançon lowered his gaze. Laure Moysset, a journalist who had covered the case since 1997, told Sud Radio that it had left lasting fear in the city: young women had been afraid to go out at night, and some parents had forbidden them to travel alone. Slate reported residents describing the same change of habit: avoiding the area, driving instead of walking, and not letting young women go out alone.
The second day belonged to experts. A psychiatrist told the court that assessing the accused's social dangerousness was a matter for a crystal ball. Another expert reported that Rançon had told him the only thing he regretted was the death of a person he called Johnny, who was not otherwise identified. On the third day, March 7, Rançon's former partner from Amiens, with whom he had lived for five years, described him in court as despicable and said she would seek a change of her son's surname. His eldest son testified that he had met his father in 2011, through the father's later partner, and had stayed with him for several weeks in Perpignan; he said they had exchanged only a few letters when he was a teenager. Rançon told the court, in brief remarks to his son, that he was sorry for having been a poor father and that they would probably not meet again.
The fourth day brought the testimony of Rançon's partner from 2005 to 2012, with whom he had two children. She described the relationship at length, and said she left in 2012. A complaint she had filed with police about him resulted in the collection of his DNA. The prosecutor tied that sequence to his presence in the dock.
On Wednesday, March 14, the court examined the killing of Marie-Hélène Gonzalez. Rançon, who often answered "I do not remember" during the trial, was largely silent. Two of Marie-Hélène Gonzalez's brothers, in tears, jumped over the benches and ran toward the glass dock to strike him; police officers stopped them and escorted them out. Sud Radio called the scene surreal and said the trial had been marked by hatred from the start. The presiding judge reprimanded the public and reminded the room that justice was not a form of revenge.
The prosecutor, Luc-André Lenormand, asked for the maximum sentence and described a sadistic dimension in the accused's conduct, according to the AFP dispatch carried by Sud Radio. Lawyers for the civil parties spoke next. Etienne Nicolau said that "the life sentence you are about to pronounce does not compensate for the families' life sentence." Rançon's lawyer Gérald Brivet-Galaup said that he, like the jurors, had wondered how a human being could sink so low, and reminded them that the city had waited twenty years for a decision.
Before the jury retired, Rançon stood and said: "I am sorry for what I did, and I ask your forgiveness." He added that Marie-Hélène and Moktaria "should never have died." Slate also reported that in an interview he had said he no longer remembered the attack on the young woman who survived, calling it a minor matter.
On Monday, March 26, 2018, after about six hours of deliberation and three weeks of trial, the jury found him guilty on all counts: the rape and murder of Moktaria Chaïb and of Marie-Hélène Gonzalez, the attempted murder of the young woman who survived, and the attempted rape of the other. The court sentenced him to life imprisonment with a security period of 22 years, the maximum. Slate reported that the term meant he could not be released before about the age of 76. He showed no reaction as the verdict was read.
Relatives left the courtroom after the verdict: a sister of Marie-Hélène Gonzalez with the brother of Moktaria Chaïb, and Marie-Hélène Gonzalez's mother with the two investigators.
Isabelle Mesnage was 20 years old when she was killed in July 1986 near Amiens. Her death was discovered on July 3 of that year. The case was closed in 1992 without charges, by a decision known in French law as a non-lieu.
Her parents did not accept that outcome. Over the following decades they pursued the case with the help of Corinne Herrmann, a lawyer who specializes in unsolved cases. Europe 1 reported that the family's lawyers learned of Rançon's trial in Perpignan, where he was accused of killing two women in similar circumstances. A court conviction in Perpignan had established that Rançon lived in the Amiens area in 1986, which led the Amiens prosecutor to reopen the investigation in 2017.
According to the AFP reports on the appeal, a new forensic examination of the file found strong similarities with the Perpignan cases. In 2019, gendarmes took Rançon out of Béziers prison and held him in custody at the local gendarmerie station over the 1986 case. During his seventh custody session, and again before the investigating judge, he confessed to the rape and killing. He retracted later in a letter, saying that investigators had put pressure on him, and he denied the crime at both trials.
In 2021 the Somme assize court in Amiens tried him for the rape and murder of Isabelle Mesnage. It convicted him on a Saturday and imposed 30 years of criminal detention, with a 20-year security period, according to Europe 1. The jurors followed the requests of the prosecutor, and Rançon denied the crime at trial.
The 30-year sentence did not survive. The prosecutor general, André Meykuchel, argued that the term was legally flawed: a sentence of that length did not exist in French law in 1986, when the crime was committed, and the law cannot be applied retroactively. An appeal trial opened on a Monday in June 2022 at Laon, in the Aisne, and was scheduled to run to the end of the week. Rançon, then 62, was represented by Gérald Brivet-Galaup, who asked for his acquittal on the ground that convicting the wrong person risks leaving the guilty one free. The lawyer for the civil parties, Didier Seban, asked that the specialist Paris unit for unsolved cases examine Rançon's wider criminal record.
On Friday, June 24, 2022, after about four hours of deliberation, the Aisne assize court of appeal sentenced him to life imprisonment with a security period of 18 years, matching the prosecutor's request. He was convicted of the rape and murder of Isabelle Mesnage, a charge he continued to deny. He remained impassive as the verdict was read. His other lawyer, Xavier Capelet, said he was not really surprised, that the defense felt it had not truly been heard, and that it would not ask the Court of Cassation to review the ruling.
Isabelle Mesnage's family had pursued the case for 35 years. Corinne Herrmann said afterward that it is never too late to reopen an old case.
The record has three legally separate parts. The 2018 verdict covers the two Perpignan killings and two further counts, and nothing else. The 2021 and 2022 proceedings cover only the death in 1986. Rançon's own statements shifted. For the Perpignan cases he confessed in October 2014, retracted in March 2015 and confessed again in June 2015. For the Picardy case he confessed in 2019, retracted in a letter and denied the crime at both trials. The courts convicted him in each case. The 30-year term imposed in Amiens in 2021 was challenged by the prosecutor general as unlawful, and the court at Laon imposed life imprisonment in its place.
