French police officers

François Vérove (French pronunciation: [fʁɑ̃swa veʁɔv]; 22 January 1962 – 29 September 2021), also known as Le Grêlé ([lə ɡʁɛle, ɡʁele], the "Pockmarked Man"), was a French serial killer, rapist and police officer who murdered at least three people between 1986 and 1994 in the Île-de-France region. He received his nickname from acne scars seen on his face by witnesses following his first murder. Vérove committed suicide in September 2021 upon realizing that he was about to be identified.
Vérove's first murder, that of 11-year-old Cécile Bloch, took place in the 19th arrondissement of Paris in 1986. The following year he murdered two adults in the 4th arrondissement. He was linked to two further murders in 1991 and 1994, as well as two rapes in 1987 and 1994. During his crime spree, Vérove belonged to various French police forces; he was a member of the National Gendarmerie between 1983 and 1988, serving as a motorcyclist in the Republican Guard, then became an officer in the National Police in Paris until his retirement in 2019. He briefly held elected office as a municipal councillor in Prades-le-Lez, Hérault, between 2019 and 2020.
On 24 September 2021, Vérove received a police summons to provide a DNA sample as part of an investigation into the Bloch killing. His wife reported him missing on 27 September. Two days later, Vérove killed himself by barbiturate overdose in a rented flat in Le Grau-du-Roi, Gard. He left behind a suicide note in which he confessed to his crimes.

Georges Nguyen Van Loc (2 April 1933 – 7 December 2008) was a French policeman, actor, and author.
Van Loc worked as a policeman, police inspector and commissioner in his native Marseille for many years. He later wrote an autobiography about his career as a police officer and played himself in a television series based on his life. He created the first GIPN. He was nicknamed "le Chinois" ("the Chinese") despite his Vietnamese descent.

Lucien Aimé-Blanc (23 March 1935 – 19 February 2020) was a French police officer. Born in Marseille, he became vice chief of staff of the Research and Intervention Brigade (BRI) and also of the Narcotics brigade. He led the Office central de répression du banditisme (OCRB).
Lucien Aimé-Blanc revealed in L'Indic et le Commissaire (2006) that left-wing activist Pierre Goldman had been assassinated on 20 September 1979 by a commando of the GAL, a Spanish assassination squad, led by Jean-Pierre Maïone. According to Aimé-Blanc, Henri Curiel, a anti-colonialist opposed to French Algeria may also have been the victim of the same Jean-Pierre Maïone, who was his informant for years.

Olivier Marchal (born 14 November 1958) is a French actor, director, screenwriter, and a former policeman. In 2005, he was nominated for three César Awards (best director, best film and best writing) for his film 36 Quai des Orfèvres. He also created the popular French television police drama Braquo and wrote and directed some episodes in its first season (2009).

Roger Borniche (7 June 1919 – 16 June 2020) was a French author and detective of the Sûreté nationale.
Borniche was born in Vineuil-Saint-Firmin, Oise. He started as a singer, but his fledgling musical career was interrupted by the German invasion of 1940. To make a living, he took a job as a store detective. In 1943, he joined the Sûreté nationale as Inspector to avoid being shipped to a forced labour detail. Assigned to hunt the Resistance, he instead helped partisans escape from occupied France. He deserted in 1944, only days before the D-Day invasion.
Upon the liberation of France in August, he was reinstated to the Sûreté nationale and assigned to enforce France's abortion laws. The next year, he was transferred to a homicide unit.
