A 28-year-old Spanish man has been arraigned for killing his own mother, chopping up her body into pieces and sharing them with his dog.

Alberto Sanchez Gomez, now known as the “cannibal of Ventas,” was arrested after police turned up at his family home in Madrid to inquire about missing OAP Maria Soledad Gomez.

Shocked cops found her body parts in at least six large Tupperware containers inside the flat near the Spanish capital’s famous Las Ventas bullring. Her vital organs were missing and part of her intestines were found mixed with domestic waste inside the flat.

According to the indictment, the incident occurred in early 2019 when Alberto had a row with his 69-year-old mother at the flat they shared in Ventas next to Madrid’s famous bullring.

During the confrontation, he strangled his mother then dragged her into her bedroom where he used a saw and two kitchen knives to cut her up “in order to get rid of the body”, it said.

“Once he had started cutting up the body, he began eating the remains over the course of about 15 days, storing other parts in various plastic containers around the house and in the fridge,” it said. He also put some of the remains into plastic bags and threw them into the bin.

At the start of his trial , Alberto admitted to hearing “hidden messages” when he watched TV and voices telling him: “Kill your mum.” He told Madrid’s Audiencia Provincial court that the voices were those of neighbours, acquaintances and celebrities.

But he insisted he didn’t remember cutting up his mum or eating her remains after a worried friend who hadn’t seen her for a month raised the alarm.

Officers who got him to open the door of the apartment they shared are said to have received the response, “yes, my mother is in here, dead” when they asked after her.

Testifying in court, a police officer who entered the flat said the suspect told them he had eaten some of the remains raw, while other parts he had cooked or given to the dog, local media reported.

“We found a hellish scene,” an unidentified police officer told Telecinco news channel, with police saying the suspect was known for having drug issues.

Prosecutors want him jailed for 15 years and have called for him to pay 90,000 euros ($110,000) in compensation to his older brother.
