Lucien Léger, born in Paris on March 30, 1937, and died in Laon in July 2008, was a French criminal, sentenced to life imprisonment for the murder of a child in 1964. He was the oldest detainee in France before being released on October 3, 2005, after 41 years of imprisonment, which constitutes one of the longest detentions in Europe (it does not, however, equal that of serial killer John Straffen who was detained for 55 years in the United Kingdom). He was nicknamed the Strangler by the press because of the signature "Strangler No. 1" affixed to the bottom of anonymous letters sent to the police.
