The Poisoner Who Never Confessed: Yiya Murano

Woman Walks Out of Prison and Appears on Television with Cakes: The Cyanide Deaths of Carmen del Giorgio, Nilda Gamba, and Lelia Formisano

Buenos Aires, 1979. Three middle-class women die within weeks of each other, each certified as natural death. Then an autopsy reveals cyanide in the first victim's body. Two exhumations follow. All three contained the same poison. One person connected them all: a soft-spoken, charming woman who brought cakes on visits and managed their savings.

This investigation explores how three deaths certified as cardiac failure became murders, yet the poisoning method was never established. We examine the doorman's testimony, the missing promissory notes, the psychiatric profile of a woman prosecutors called an intelligent psychopath-and the inexplicable gap between an acquittal in 1982 and a conviction in 1985, separated by three mysterious years.

Victim: Carmen Zulema del Giorgio, Nilda Gamba, Lelia Formisano
Date: February-March 1979
Location: Buenos Aires, Argentina
Status: Convicted; Released 1993
