A man, identified as Alvaro, has been arrested in Mexico for allegedly eating his wife's brain in tacos after killing her.

He was arrested from his home in Pueblo on July 2.

Alvaro married Maria Montserrat, 38, less than a year ago. She had five daughters, aged from 12 to 23.

The accused has confessed to eating part of his wife's brain in tacos and using her shattered skull as an ashtray. He dismembered the victim's body and placed it in a plastic bag.

Two days after the alleged murder, the accused reportedly called one of his stepdaughters to confess his crime. "He told one of her daughters to come and collect her mum because 'I already killed her and put her in bags'," said the victim's mother Maria Alicia Montiel Serran.

Serran added that the man chopped up her daughter's body "with a machete, a chisel, and a hammer".

"Drugs, he used them, and he snorted cocaine and everything. Well, I think he had mental problems because to do something like that...,” Ms Serran was quoted as saying.

The family also accused him of physically and sexually harassing the victim's daughters.
