He descends the stairs accompanied by the governess with whom he speaks in French, which infuriates one of the guards who orders him to speak in Spanish. Calvo Sotelo has told him to warn his brothers Luis and Joaquín, but not his father who is suffering from a stomach ulcer that keeps him in bed —according to Ian Gibson, what he told him was to warn his friends and colleagues Andrés Amado and Arturo Salgado Biempica—. He meets the doorman of the estate to whom he says: "They are taking me under arrest. I have not been able to talk on the phone." Upon arriving at the van he is ordered to sit in the third apartment facing the march,"The vans, or 'platforms', as they used to be called, of Assault, were open, long and powerful vehicles, of Hispano-Suiza make. They had four compartments and six benches, with numerous doors that facilitated the rapid intervention of their occupants in those street disturbances in whose control they were destined. The 'platforms' could easily carry twenty men or more." ( between two uniformed guards (one of them Aniceto Castro Piñeira). The bench in front is left unoccupied. Luis Cuenca is in the rear apartment. Captain Condés is seated next to the driver and next to him José del Rey (although he will deny it before the Francoist judges). Van number 17 starts off in the direction of Alcala Street. When it arrives at Ayala Street, Luis Cuenca shoots Calvo Sotelo twice in the back of the head, killing him on the spot.: "In subsequent statements, some of the detainees say that it was first a single shot in the back of the head, and that the second was fired when the victim was already down. From the very detailed report of Dr. Piga and the autopsy certificate it seems to be deduced that the shots were almost simultaneous and the photograph shows the orifices very close to each other." The body collapses on the floor of the van and is wedged between the two seats. Captain Condés does not make any comment nor does he order the truck to stop when he hears the shots, he limits himself to tell the driver to go to the East cemetery.: "Nor is it easy to believe that a captain of the Civil Guard would have tolerated, without even commenting, that a gunman would kill a person he had taken into custody, even illegally kidnapped. [...] Condés knew Cuenca, and he did not object to the latter's standing behind Calvo Sotelo, assuming that it had not been agreed beforehand." According to one of the guards who was in the truck, when the shots rang out "Condés and José del Rey exchanged glances and smiles of intelligence", which Del Rey denied before the Francoist judges.
