On the morning of 2 July, the neighbors of number 109 of Fuencarral Street alerted the police of a strong smell of oil and burnt flesh coming from the second floor, on the left side of the building. The police broke down the door of the small apartment and found the lifeless body of Luciana Borcino, widow of Vázquez-Varela (known around the neighborhood as the widow Varela) lying face up on her bed and covered with rags doused in lamp oil that had previously been burned inside the closed room. The widow Varela, originally from
Vigo and a resident of Madrid for many years, was a wealthy woman, known around the city for her charity works. She had been stabbed three times, one of them through the heart, which caused her death. The preliminary investigation showed no evidence that robbery was the motive. He was a suspicious character, a bohemian who lived a disorderly life and who had a bad reputation due to the company he kept. Neighbors claimed they often heard violent arguments between him and the widow Varela because she refused to give him money. However, he had spent the evening before the crime in the
Cárcel Modelo prison due to having stolen a cloak. since she sold lottery tickets on the corner of Alcalá and Sevilla streets. Despite Varela being in prison at the time of Luciana's murder, the housemaid Higinia insisted on her account of the facts. According to her,
Pollo Varela had threatened and coerced her with force, even offering her money, and thus she had gone to buy the oil, had cleaned up the blood after the murder, burnt the body, and closed the door after her. She claimed that she had fainted after the crime due to the psychological stress she had been under. Higinia's illogical and changing statements would soon raise the suspicions of the police about her and her environment. During the statements, another name was mentioned as potentially being involved, that of
Lola la Billetera who, apart from being
Pollo Varela's lover, was a close friend of Higinia. Other sources, such as Pérez-Galdós himself and various journalists and historians, have referred to her by the name Dolores Ávila. ==Impact on Madrid and Spanish society==
