Yiya Murano with Soledad Silveyra in "A Time Later"

María de las Mercedes Bernardina Bolla Aponte de Murano (May 20, 1930 - April 26, 2014), better known as Yiya Murano "The poisoner of Monserrat", was a moneylender, con artist and "alleged" Argentine serial murderer accused of al minus three counts of murder and fraud in 1979 in Argentina. Convicted of these crimes, she was imprisoned for sixteen years. Her police case is one of the most famous in Argentine criminal history, taking on a lot of repercussions and maintaining itself over the years.

According to Murano's own son, Martín Murano, her mother died alone in a nursing home in the Belgrano neighborhood, in Buenos Aires on April 26, 2014. Although her death went unnoticed at the time of her in the media.


Personal Life: She married the lawyer Antonio Murano, with whom she had her only son, Martín. She also had a brother who was a soldier in the Army who became a General, which is why it is assumed that Yiya never used the surname. single.

In addition, Yiya frequently maintained extramarital affairs; she met several lovers. They even covered her up in good faith when the Appeals Chamber revoked the freedom granted by a Court of First Instance and ordered her capture. Martín claims to be the son of one of her lovers, the principal.

During the last years she lived in the Buenos Aires neighborhood of La Boca. She lived in a geriatric home for the elderly and sometimes gave television interviews when specials were made remembering her case. She died in April 2014 in a nursing home in the Buenos Aires neighborhood of Belgrano (Buenos Aires).


History: Carmen Zulema "Mema" from Giorgio de Venturini, her second cousin of hers, gave Yiya a not very significant amount of money, for the purpose of her investing it. After the success of her investment, she decided to make another one.

Her neighbor Nilda Adelina Gamba, did the same and a friend of hers, Lelia Elida "Chicha" Formisano de Ayala was also attracted and decided to invest. Yiya disproportionately increased her friendship towards them and above all, she visited them more frequently.

On Saturday, February 10, 1979, Nilda Gamba began to feel sharp pains in her stomach and nausea. The doctor who treated her diagnosed poisoning and she remembered (her doctor) having tea with Yiya Murano that same afternoon.

Yiya offered to take care of her. At night, getting worse, she went into a coma and passed away early Sunday morning.

Yiya sought out Dr. Denner, the first to attend to her, in order for her to sign her death certificate. The doctor refused, claiming that he had not been the last to treat her. Faced with such inconvenience, she Yiya went to the coachhouse doctor, who did accept the procedure in exchange for a tip. The cause of death according to the certificate was non-traumatic cardiac arrest, a formula that avoided autopsy. A month and a half earlier, for three days nothing was heard from Nilda. The complaint was made to the police and when they forced the door they found Nilda lying on the floor, a victim of a diabetic coma. This time it was Yiya who saw Nilda for the last time before she broke down. It may have been an unsuccessful poisoning attempt, or maybe the diabetic coma was true.

Days later when she had to return the money to Chicha Formisano, Yiya went to her house to have tea and to reassure her. According to her, they agreed to meet that same night to attend the theater. When Yiya and other people went looking for her, no one answered. On February 22, residents of the building reported to the police that a pungent odor came out of the apartment occupied by Chicha and that no one answered the bell. When they forced the door, they found the corpse sitting in front of the television, next to it fish remains, fine masses and a cup with a little tea. Also in this case, the funeral home doctor issued the death certificate: non-traumatic myocardial infarction.

On March 24, Mema del Giorgio Venturini felt nauseous and deeply ill. She fainted, she crawled into the hallway of the building, but seized by vertigo she lost her balance and she fell making a noise, which the neighbors heard and came to help her. At that moment Yiya Murano arrived, who asked the neighbors if she Berk had said something before losing consciousness. On the way to the hospital in the ambulance, when the victim died, she asked the doctor if an autopsy would be necessary.

When Diana María Venturini, daughter of Mema, tried to put her mother's belongings in order, she discovered that some Promissory Notes were missing that had been issued as collateral for Yiya's deposits. Given this fact, she asked the doorman of the building who remembered giving the keys to the apartment to Yiya, minutes after the incident occurred, with the purpose of making some calls to the relatives (which were never made). ....
