Léopold Dion (February 25, 1920 – 17 November 1972) was a Canadian sex offender and serial killer who raped 21 boys, killing four; he was active in Quebec in 1963.
Léopold Dion and his brother raped and stabbed the woman on the railway track linking the Rang Petit-Capsa (a street) to the village of Pont-Rouge.
Dion lured the boy by taking a series of snapshots with an old camera that had no film before claiming to want to continue elsewhere.
Dion, who was then on conditional release for raping a schoolteacher several years earlier, was arrested the day after his last murder.
Once in prison, Dion held out for a month before he finally admitted to his crimes in detail to his interrogators.
Dion was, in the end, charged with only one murder, Pierre Marquis', due to a lack of evidence in the other cases.
