Case Summary

Summary

Guillaume Seznec was a Breton sawmill owner who was convicted of the murder of wood merchant Pierre Quéméneur, conseiller général of Finistère, and of false promise. Pierre Quéméneur had disappeared during the night of 25/26 May 1923 while on a business trip from Brittany to Paris with Seznec. Despite the body never being recovered, the case proceeded on a murder hypothesis.

Seznec was the prime suspect because he was the last person to have seen Quéméneur alive. He was arrested, charged, and imprisoned. His trial heard nearly 120 witnesses and closed on 4 November 1924. He was found culpable, but because premeditation could not be proved, he was condemned to hard labour in perpetuity, while the avocat général had demanded the death penalty.

He was taken to the Transportation Camp at Saint-Laurent-du-Maroni in 1927 and was transferred to the prison of the Îles du Salut in French Guiana in 1928. He benefitted from a remission and was released in May 1947. He returned to Paris the following year.

In 1953, in Paris, Seznec was hit by a van driven off afterward. The driver, later questioned, claimed not to have seen anything. Seznec died of his injuries on 13 February 1954.

Throughout the trial and for the rest of his life, Seznec proclaimed his innocence. After his conviction, his descendents fought to have the case reopened and his name cleared, including his grandson Denis Le Her-Seznec. Their attempts (14 in total) failed, until a “commission de révision des condamnations pénales” accepted a reopening of Guillaume Seznec’s conviction for murder on 11 April 2005, which could open the way to an eventual annulling of his conviction in 1924. The criminal chamber of the Court of Cassation examined the case on 5 October 2006. On 14 December 2006, the Cour de révision refused to annul Seznec’s conviction, judging there was no new evidence to call doubt on Seznec’s guilt.

Background

Course Joseph Marie Guillaume Seznec was born in Plomodiern in Finistère in 1878. He was the head of a sawmill at Morlaix.

Pierre Quéméneur was a wood merchant and conseiller général of Finistère.

Quéméneur had disappeared on the night of 25/26 May 1923 during a business trip from Brittany to Paris with Seznec. The trip was linked, according to Seznec, to the sale of stocks of cars left behind in France after the First World War by the American army to the Soviet Union.

The offence

Seznec was found guilty of false promise and of the murder of Pierre Quéméneur.

A fake bill of sale, dated May 23, was found among Seznec’s belongings. During the trial, the prosecution argued that Seznec had done away with Quéméneur to get his hands on Quéméneur’s country estate and that Gherdi was “a figment of the accused’s imagination”.

Seznec insisted on his innocence.

Investigation

Seznec became the prime suspect as the last person to have seen Quéméneur alive.

The case explored multiple possibilities as to Quéméneur’s disappearance, and it remained the case that the body was never recovered.

During later proceedings, an alternative possibility of a police plot was raised, involving trainee inspector Pierre Bonny and his superior, commissaire Vidal. The possibility was raised because Pierre Bonny and commissaire Vidal were charged in the inquiry.

Experts solicited by the cour de cassation concluded that Guillaume Seznec really was the author of the false promise of sale of Quéméneur’s property seized at Plourivo.

Arrest

Seznec was arrested, charged, and imprisoned after becoming the prime suspect.

Trial

Seznec’s 8-hour trial heard nearly 120 witnesses and closed on 4 November 1924.

Seznec was found culpable, but premeditation could not be proved. He was condemned to hard labour in perpetuity; the avocat général had demanded the death penalty.

Sentencing

Seznec received a sentence of hard labour in perpetuity on 4 November 1924.

He was taken to the Transportation Camp at Saint-Laurent-du-Maroni in 1927.

He was transferred to the prison of the Îles du Salut in French Guiana in 1928.

He obtained a remission and was released in May 1947.

Appeals

His descendents continued attempts to reopen the case and clear his name, with 14 attempts in total failing until later proceedings.

A “commission de révision des condamnations pénales” accepted a reopening of Guillaume Seznec’s conviction for murder on 11 April 2005, which could open the way to an eventual annulling of his conviction in 1924.

At that point, Avocat général Jean-Yves Launay required the benefit of the doubt for Seznec, raising more particularly the possibility of a police plot and charging the trainee inspector Pierre Bonny and his superior, commissaire Vidal in the inquiry.

At his side, the conseiller rapporteur Jean-Louis Castagnède maintained the opposite opinion, deducing that any manipulation seemed improbable due to the few acts established by Bonny, and that experts solicited by the cour de cassation had established that Guillaume Seznec really was the author of the false promise of sale of Quéméneur’s property seized at Plourivo.

On 14 December 2006, the Cour de révision refused to annul Seznec’s conviction, judging there was no new evidence to call doubt on Seznec’s guilt, because the implication of inspector Bonny was not new.

Some accounts also described that the Seznec family intended at first to take the case to the European Court of Human Rights but gave up on their lawyers’ advice.

Outcome

The Cour de révision refused to annul Seznec’s conviction on 14 December 2006.

Seznec was sentenced to hard labour in perpetuity in 1924 and was released in May 1947.

Aftermath

In popular culture, Yves Boisset directed the film L'Affaire Seznec in 1992, starring Christophe Malavoy, with Nathalie Roussel, Jean Yanne and Bernard Bloch.

Denis Seznec made statements in court and afterward, including:

“It is shameful what you are doing!”

and:

“This case has ruined my life” “I don't regret it, but it has stopped me living. Now, for the first time, there may be light at the end of the tunnel”.

Judicial and legal commentary also included the following statements attributed to Denis Seznec in the context of the reopening:

“This is a historic day for our family,”

and:

“After a campaign that has lasted three generations, this is the first time that the French justice system has finally decided to drop its illusion of infallibility,”
