Boyfriend Stabbed by Girlfriend After Greeting a Woman on the Street
ARGENTINA – A couple was involved in a violent incident while walking together when the man was stabbed by his girlfriend after he greeted a woman on the street.
Mariano Grinspun, 23, and Natacha Palavecino, 32, a couple from Argentina, were walking together on October 21, 2024, at the intersection of Balboa and La Bastilla streets in González Catán. They were holding hands when they encountered a woman, known only as LC, who stopped briefly to greet Mariano. LC was a former classmate of the young man.
Natacha did not like LC’s greeting and became intensely jealous. Armed with a knife, Natacha suddenly stabbed LC in the armpit. LC fell to the ground, and when Natacha tried to stab her again, LC managed to block the attack. A man passing by saw the altercation and intervened, allowing LC to escape.
In the heat of the moment, Natacha turned her anger toward her boyfriend, Mariano, and stabbed him in the chest. Surveillance footage from the police investigation showed the couple arguing before Mariano fell to the ground. He attempted to get up but collapsed due to the chest wound. As he lay on the ground, Natacha approached him, strangled him, and killed him.
Witnesses called for help, but Mariano was already dead by the time emergency responders arrived. Police discovered that Natacha had a history of violent behavior. In 2021, she was jailed for stabbing her former boyfriend. Mariano had also reported her to the police, claiming that she had frequently threatened and harmed him. In July 2023, a court issued a restraining order against Natacha, barring her from contacting Mariano. However, when the order expired, Mariano chose to give her another chance to continue their relationship.
Mariano’s father, Ramon, shared that he had witnessed Natacha’s abuse toward his son, stating, “He wanted to have a family with her, but it was a sick thing.” A neighbor also revealed that Natacha would often abuse Mariano, treating him cruelly by attacking him with rocks, pushing him, and even making him sleep outside the house. Natacha now faces imprisonment for the murder of Mariano and for stabbing LC.
