A convicted pedophile who abused almost 200 children was stabbed to death in North Yorkshire, England, on Sunday.

Richard Huckle, 33, from Ashford, Kent, was given 22 life sentences in 2016 after he admitted to sexually abusing 71 kids whose ages ranged from six months to 12 years between 2006 and 2014, according to the BBC.

The report said Huckle was attacked with a makeshift knife while inside his cell at the Full Sutton Prison.

At the pedophile’s trial in 2016, investigators said they found over 20,000 indecent photos and videos of his assaults, which were shared with other pedophiles via a site on the dark web called The Love Zone.

Reports said that prior to his arrest, Huckle posed as an English teacher and Christian volunteer worker in Kuala Lumpur, Malaysia, where he groomed impoverished children.

In one of his online posts, Huckle reportedly wrote “Impoverished kids are definitely much easier to seduce than middle-class Western kids.”

Reports said he attempted to make money from his crimes by crowdfunding the release of the photos.

“Huckle also created a 60-page ‘how-to’ guide for other pedophiles seeking to evade being caught, and kept a scorecard and points system regarding the children who were abused — leading investigators to speculate he may have as many as 200 victims,” a Fox News report stated.

At his sentencing in 2016, Judge Peter Rook condemned Huckle for his heinous crimes he said had become routine for the pedophile.

Rook commented:

Your offending behavior became entrenched in your everyday life. Your life revolved around your sexual activities with young children. Your distorted beliefs in respect of children are deep-seated. Your self-delusion knows no bounds. It is also clear that, had you not been arrested, you planned to continue the same lifestyle using the expertise that you were keen to show off to and share with other abusers so as to continue your sexual exploitation of the children of such communities.

Reports said prior to his death, Huckle refused to cooperate with authorities when they tried to unlock a cache of encrypted files he had access to that may contain the names of victims and other pedophiles, according to Fox News.
