The young victim has been identified as Silvina Nunez. The attack on the deceased took place at their home in the city of Florencio Varela in Greater Buenos Aires, Argentina.
Mauricio Canosa Fratti had had an argument with his wife Victoria Nunez, 20, because her child was crying so much. Afterwards, Mauricio raped the girl, beat her all over, then when she was dead he washed her naked corpse.
The mother only reported the killing the following morning after which the police searched the city for Mauricio, finding him in the area of San Francisco Solano trying to ‘hide out’ in a relative’s home.
Police arrested Silvina's mother alongside the stepdad because it is believed she must have gone along with the crime to some extent as it was impossible for her not to have been aware that such a savage attack was going on in their small farmhouse. Also, the fact that she waited until the next day to report the crime, hints at a degree of complicity.
