The lifeless body of the 33-year-old was on Sunday, October, 13, found 'slumped' in his top-floor cell at HMP Full Sutton, a Category A jail near York, housing many of Britain's most notorious and violent prisoners.
Huckle's death comes three years after he was jailed for least 25 years for raping and sexually assaulting 200 children in south-east Asia.
Posing as English teacher and Christian volunteer, he abused children from the age of six months to 12-years-old over a nine-year-period between 2006 and 2014.
According to Mail Online, Richard targeted care homes and orphanages while teaching English and photography in Malaysia and Cambodia, and even bragged about the abuse in a blog in which he awarded himself 'PedoPoints.'
He also filmed himself raping children and babies. From the age of 19, he amassed a staggering 20,000 images of child abuse that he sold for profit.
At that time, Investigators believe he would have attacked hundreds of more children if he hadn't been caught in 2014 when Australian police uncovered a network of paedophiles on the 'dark' web.
During his trial at the Old Bailey in 2016, Richard Huckle admitted an unprecedented 71 charges over eight years, including rape, sexual assault and sexual activity with a child.
