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.

Ronald Clark O'Bryan (October 19, 1944 – March 31, 1984), nicknamed The Candy Man and The Man Who Killed Halloween, was an American man convicted of killing his eight-year-old son Timothy (April 5, 1966 – October 31, 1974) on Halloween 1974 with a potassium cyanide-laced Pixy Stix that was ostensibly collected during a trick or treat outing. O'Bryan poisoned his son in order to claim life insurance money to ease his own financial troubles, as he was $100,000 in debt. O'Bryan also distributed poisoned candy to his daughter and three other children in an attempt to cover up his crime; however, neither his daughter nor the other children ate the poisoned candy. He was convicted of capital murder in June 1975 and sentenced to death. He was executed by lethal injection in March 1984.
