A blood-written message at the crime scene became one of the most famous pieces of evidence in modern French criminal history. Omar Raddad was convicted, partially pardoned and released, but never judicially exonerated.

Ghislaine Marchal, a 65-year-old widow, was found dead at her villa in Mougins on June 24, 1991. Her gardener, Omar Raddad, was convicted of her murder in 1994 and sentenced to 18 years. The conviction has survived repeated attempts at review, even though later DNA findings and questions surrounding the investigation have made the case a continuing subject of debate.
Marchal was found in a utility or boiler-room area of her property after she had failed to answer calls. Investigators focused immediately on two phrases written in blood, the best known reading “Omar m'a tuer”. The grammatical error in the phrase became a central public controversy because Marchal was an educated native French speaker.
Authorities concluded that Marchal herself had written the message while injured and interpreted it as naming Raddad. The defense challenged both that conclusion and the broader reconstruction of the crime.
Raddad, a Moroccan gardener who worked for Marchal, was arrested and consistently denied killing her. The prosecution relied heavily on the blood-written message and circumstantial evidence. The defense argued that there was no direct forensic evidence tying him to the killing and raised questions about the timing of death, handwriting and the handling of the scene.
The case drew intense attention in France because it combined a sensational piece of evidence with arguments about language, class, immigration and the reliability of the investigation. Those broader debates, however, are separate from the legal fact that a criminal court returned a guilty verdict.
On February 2, 1994, the Alpes-Maritimes assize court convicted Omar Raddad of murdering Ghislaine Marchal and sentenced him to 18 years' imprisonment. Contemporary reporting records that he continued to maintain his innocence after the verdict.
The conviction is the operative judicial finding and must not be confused with later political clemency. In 1996, President Jacques Chirac granted Raddad a partial pardon, reducing the sentence. A pardon changes punishment; it does not erase a conviction or declare a person innocent.
Raddad was conditionally released in September 1998 after serving more than seven years. French reporting at the time explicitly noted that the partial pardon and conditional release did not overturn the guilty verdict.
He continued seeking review of the case. In 2002, the Cour de révision rejected an application for a new trial, concluding that the material presented did not meet the legal threshold for reopening the conviction.
Subsequent testing identified male DNA profiles on preserved items from the scene that did not match Raddad. The defense argued that the findings justified a new trial. Prosecutors and courts emphasized a critical limitation: the presence of unidentified DNA does not by itself establish when or how the genetic material was deposited, or prove who killed Marchal.
In December 2021, the review commission ordered additional investigation into the new material. That procedural step was widely described as reopening examination of the case, not as overturning the conviction.
On October 13, 2022, the commission examining the second review request declared it inadmissible. As a result, the 1994 conviction remained in force. Raddad and his lawyers continued to contest the result publicly, but no later acquittal or retrial has displaced the conviction in the sources reviewed for this file.
The enduring controversy comes from the combination of the blood inscription, the absence of a simple direct-forensic narrative, disputed expert interpretations and unidentified DNA profiles found years later. Those issues justify describing the case as contested, but they do not justify rewriting the current legal status.
Crime by Region therefore classifies the file as adjudicated but contested: Omar Raddad was convicted of Marchal's murder, received clemency affecting his sentence, was released, and has not been judicially exonerated.

A pardon, conditional release, disputed evidence and unidentified DNA are not the same as an acquittal. This page reports the controversy in full while retaining the legal status created by the 1994 conviction and the later rejection of review requests.
