Vincenzo Aiutino (born 10 March 1970) is a French serial killer popularly known as "the man with fifty affairs".
Convicted of three murders in the Longwy commune, he was sentenced to life imprisonment on 6 March 1998, along with 18 years of preventive detention without parole.
Aiutino worked at a construction site in Belgium as a teenager but was briefly admitted to a psychiatric institution in 1985 after he exposed himself to a woman.
Upon reaching the parking lot of the Auchan supermarket in Mont-Saint-Martin, she was approached by a stranger, who lured her back to a construction site under the pretence of helping him carry a heavy object.
He led her to the cellar on his building site under the same pretence of helping her lift a heavy object, where he raped, strangled, and murdered her by hitting her with an iron rod.
While the murder was originally considered a potential suicide, police soon began investigating the death as a sexual crime, after reviewing the files of sex offenders in the region.
On 2 December 1991, inspectors from the regional police of Nancy interrogated him, but due to a lack of evidence, they released him after 10 hours in custody.
On 25 February 1992, Aiutino punctured the tire of Bernadette Bour, a 40-year-old medical sales representative, and started helping her repair it.
