Thirty-two-year-old José Miguel B.V. was arrested by Spanish police on Thursday after confessing to the murder of his girlfriend Carolina C.C., who had been missing for over a month.

The butcher from the small municipality of Cifuentes in Guadalajara told police he had argued with his girlfriend and killed her with a blow to the head, Spanish news agency EFE reported.

He then chopped up her body and took her to La Riba de Saelices, a nature reserve close by, where he dumped her in a pit used as a feeding spot for vultures.

Cifuentes neighbours reported Carolina missing in the following days, their suspicions having been aroused by her ex-husband’s arrival in the small municipality.

The man, who had a restraining order out against him, had been asked by José Miguel to pick up Carolina’s four children after her 'disappearance'.

The fact that Carolina's boyfriend did not report her missing raised police suspicions and on Thursday he confessed to her murder.

Spanish Civil Guard have found part of Carolina’s trunk at the site where José Miguel confessed to having dumped her.
