Natalia Sandberg was instrumental in incriminating Leonardo David Sena, sentenced to 27 and a half years in prison. "It's on our nightstand," said Lola's mother, who thanked her for her decisive intervention.

Adriana Belmonte (56), along with her husband, Diego Chomnalez (65), has eternal gratitude to the geneticist who made it possible for the crime of her daughter, Lola Luna ChomNalez, to go unpunished. The 15-year-old Argentine girl was murdered in December 2014 while spending the summer on the Uruguayan beach of Barra de Valizas, was navigating stagnation and leading to impunity. The genetic traces found at the crime scene had already been compared hundreds of times with the DNA of those detained in the country without yielding any clues. However, one woman suggested deepening the DNA analysis and working on the maternal and paternal lines separately. This is how they reached a man who had been detained since 2015, the half-brother of the alleged perpetrator. Lola Chomnalez was found murdered on the beach in Barra de Valizas, Spain. The DNA of her alleged attacker matched that of a prisoner through a link by the maternal line. The suspect had committed crimes in 2003 and 2009, but his fingerprints were not in the Scientific Police database because it was created in 2012. This is how the idea "follow the DNA trail through the patrilineal line" arose.
