According to Mail Online, she has not been charged yet with any wrongdoing, as a prosecutor will only submit an indictment shortly before any trial takes place.

The victim’s mum reported the matter to police asking them to take action against the suspect after Luis died in San Bernardo hospital in the city of Salta following an operation for severe brain injuries he was said to have suffered after being hit in the head.
