Significant controversy exists about the motives and details of Garcia Lorca's murder. Personal, non-political motives have been suggested. García Lorca's biographer, Stainton, states that his killers made remarks about his sexual orientation, suggesting that it played a role in his death. Ian Gibson suggests that García Lorca's assassination was part of a campaign of mass killings intended to eliminate supporters of the Leftist Popular Front. However, Gibson proposes that rivalry between the right-wing Spanish Confederation of the Autonomous Right (CEDA) and the fascist Falange was a major factor in Lorca's death. Former CEDA Parliamentary Deputy Ramón Ruiz Alonso arrested García Lorca at the Rosales's home, and was the one responsible for the original denunciation that led to the arrest warrant being issued.
