Léopold Dion

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. He was nicknamed the "Monster of Pont-Rouge".

On 17 November 1972, Dion was stabbed to death by a fellow inmate named Normand Champagne (also known as "Lawrence d'Arabie", or Lawrence of Arabia) who was later found not guilty of this crime by reason of insanity.

Criminal lawyer Guy Bertrand defended Dion at his trial. Dion was, in the end, charged with only one murder, Pierre Marquis', due to a lack of evidence in the other cases. On 10 April 1964, Judge Gérard Lacroix sentenced him to be hanged.

On 5 May 1963, Dion crossed paths with eight-year-old Alain Carrier and 10-year-old Michel Morel. He used the same ploy to lure them into his car, driving them to a run-down building in Saint-Raymond-de-Portneuf. With the former, he pretended to play prisoner so that he could tie the boy up in the cottage. Once he had been overcome, Dion turned to the latter one, whom he led outside, whereupon he asked the child to take his clothes off. Dion then strangled him with a garrote, before going back inside to smother the other boy.

On 26 May 1963, he met 13-year-old Pierre Marquis, who was also taken in by the fake photographer’s promises. They were a couple of paces from a dune, the same one that had become Guy Luckenuck’s grave a bit more than a month earlier. Once again, Dion asked his victim to pose naked. The child complied, but when Dion tried to assault him, he fought back before succumbing to the assault. Dion strangled Marquis.
