A twisted former butcher who confessed to brutally murdering his wife and dismembering her body was lashed yesterday by her family members as a judge sent him to prison for 20 years.

Edwin Fuentes, 44, had agreed as part of a plea deal to show cops where to find the remains of his wife, Reina De Los Santos, 42, a mother of two whom he choked to death in 2007.

At his sentencing yesterday, he was confronted by De Los Santos’ sister.

“I hope they take care of you in prison, cut you up like you did my sister and take out your organs one by one,” said Marisol De Los Santos.

“Your mother must be turning over knowing she carried a demon like you in her womb.”

Fuentes was abject in his apology to the family, concluding, “God bless you.”

Queens Judge Gregory Lasak was unmoved.

“No matter what the sentence, this will never fill the hole in the family’s hearts,” he said.
