The complaint of the young woman who claims to have been abused by the defender of the Argentine National Team is more than a year old. The complainant's lawyer circulated the testimony against the world champion, accused in the case.

The case fell to the Prosecutor's Unit Number 3 for Gender Violence of La Matanza, then in charge of Dr. María Catalina Barrios. The first complaint was on January 10, 2019, but then it did not name Montiel but rather an alleged friend of the player, Alexis Acosta. In March of last year, when Montiel was already the author of the penalty that allowed Argentina to become world champion in Qatar 2022, Carolina declared in court that the defender was the one who had abused her, that they had given her alcohol and that she fainted. She is now represented by Raquel Hermida, a defender in many cases of sexual abuse and who became known for being the defense of Nahir Galarza, who was sentenced to life imprisonment for murdering her boyfriend.
