[1] Escobedo's friend Javier Anastasio de Espona fled before being brought to trial, but much later asserted his innocence.
On 8 April 1981, Escobedo was arrested and confessed to police, after some pistol cartridges were discovered at a property belonging to his father and appeared identical with those used to kill the Marquesses.
[3] The next day, Javier Anastasio de Espona, a friend of Escobedo, and Diego Martínez Herrera, butler to the Urquijos, separately travelled in haste to London, where Juan, the son of the Marquesses and Miriam's younger brother, was living.
Escobedo maintained his innocence, accusing Anastasio of the crime, until his death in the prison of El Dueso on 27 July 1988.
[5] In February 1990, Mauricio López-Roberts y Melgar, Marquess of Torrehermosa, was sentenced to ten years in prison for obstruction of justice.
[6] The case also inspired the film Solo o en compañía de otros ("Alone or in company": 1991), with Juan Ribó and Ana Álvarez,[8] and the episode The crime of the Marquesses of Urquijo (2010) in the television series La huella del crimen, on Televisión Española.
