BUENOS AIRES, ARGENTINA – MAY 21, 2025 A family massacre in the Villa Crespo neighborhood shocked all of Argentina. When the Seltzer family's maid arrived at their home as usual, she was shocked to find the body of her 12-year-old son, Ivo, lying on the floor. She immediately called the police, who searched the entire house and discovered that all four members of the family had been murdered.
At first, it was believed that the perpetrator was the father, Bernardo, because, based on experience, these types of acts are usually committed by men. However, the investigation revealed that the perpetrator was the mother, Laura Leguizamón (51). One of the main pieces of evidence pointing to her was a letter found, in which she wrote many nonsensical things, such as: “we went out into the street,” “he was very bad, perverted,” “it was too much,” “I love you all.”
Laura was being evaluated for possible schizophrenia. She had shown signs of the illness for two years prior to the act. Since March, she had been taking antidepressants and antipsychotics, but was still waiting to receive regular therapy. The family's domestic worker confirmed the worsening of her condition, saying that she had been irritable about everything lately.

Investigators managed to reconstruct the case. She first murdered her husband while he was asleep. He received three stab wounds to the chest. He died before he could defend himself, as no signs of struggle were found on his body. Laura then went to her sons’ room, Ivo and Ian. Twelve-year-old Ivo tried to run when he heard what was happening, but was caught and stabbed 12 times in the back. His brother Ian was hiding in his room, but he too was murdered in the same way.
Laura then lay down in bed next to her dead husband and, in a psychotic state, tore out her hair and scratched her neck with her fingernails. She then stabbed herself in the heart and went to the bathroom, where she died.
