A coup d'état took place on 18 July 1931 in Seville. The fallout of this event quickly reached Utrera where a worker was shot and killed by the Guardia Civil. Luna had a residence on Calle de la Fuente in Utrera at the time. The shooting caused Luna to return to her hut, which she had been renting out at the time. Two of her children stayed behind. Dalia remained in the city as a volunteer nurse attached to Casa de Socorro. Rafael joined Republican militiamen in the city.
