Police arrest son in probe into mystery death of Madrid lawyer

The unsolved murder of a lawyer at her home in Madrid on July 1 took a dramatic turn on Monday with the arrest of her son as the presumed culprit.

Investigators assumed María Ángeles Lousa Gayoso had been killed by burglars, as her son reported to police. Ramón María Sánchez Lousa claimed that he had surprised three thieves and had been hit on the head when they fled. His mother had died from a single blow to the head. The police, though, became suspicious that no signs of forced entry were apparent and nothing showed up on security cameras.

Lousa Gayoso lived in the capital's upscale Puerta de Hierro neighborhood, which is full of surveillance devices, and her home was adjacent to the Ivory Coast Embassy.

DNA recovered from the victim's fingernails and a piece of glove shocked investigators: the profile matched that of her son. He is expected to appear before a judge on Tuesday. "The motive for the crime? That is the great mystery. Only he can tell us that," said investigators.
