The children of Castro Urdiales tried to flee by driving the car with their mother's body inside after killing her at home. The intention, as investigation sources reveal to EL MUNDO, was to escape from her by driving her mother's car, with her inside it.

One of them fatally stabbed her in the neck with a knife. After her, sources from her investigation specify, they stripped her naked - something that baffles the agents investigating the circumstances of the case - and put a garbage bag on her head.
