Nicolás Mattioli, the son of late Argentine singer Leo Mattioli, was sentenced to three years in prison for the negligent homicide of Claudia Laura Decurgez, a cyclist who was struck and killed in September 2024 in Santo Tomé. The sentencing took place during a consensual procedure overseen by Judge Susana Luna, which included a seven-year driving ban as part of the ruling. The agreement was jointly proposed by prosecutor Rosana Marcolín and defense lawyers Norberto Berlanga and Facundo Colinas, resulting in a conviction for 'aggravated homicide due to reckless driving.'

The court ruled that, due to Mattioli's lack of prior criminal record, he would serve his sentence in freedom but under strict conduct rules. These rules include a ban on approaching the victim's family members and a mandatory traffic safety course. Mattioli's case has attracted media attention not only because of his father's fame but also due to the tragic nature of the incident, raising discussions around road safety and the responsibilities of drivers towards vulnerable road users like cyclists.

Following the hearing, the prosecutor expressed the need for accountability in such cases, emphasizing the importance of adhering to traffic laws to prevent future tragedies. This case reflects broader societal concerns regarding road safety in Argentina, where incidents of reckless driving are often prevalent, and it highlights the legal consequences that can arise from such negligence, ultimately aiming to enhance public awareness and promote safer driving practices in the community.
