Police officer dismissed with conviction for gender violence and charge relating to traffic death
The San Juan Police permanently separated Alex Simón Aciar, an officer with a judicial conviction for violence against his ex-partner and facing charges of negligent homicide stemming from a traffic incident in 2021, according to canal13sanjuan.com.
The measure was adopted following the processing of an administrative inquiry by the Under-Secretariat for Inspection and Control of Public Security Management. The case concluded that Aciar had committed a serious administrative violation and that the maximum available disciplinary sanction should be applied: dismissal.
The central element of the inquiry was a sentence that convicted the officer to one year of conditional imprisonment for aggravated minor injuries on account of the relationship, simple threats and attempted aggravated theft, all offences committed against his ex-partner.
To that conviction was added a report from the Police Health Department that determined that Aciar was not psychologically fit for security duties. As a consequence of that evaluation, his reassignment to administrative functions and the removal of his service weapon had been recommended, according to 0264 Noticias.
The case file also noted that the officer had remained under preventive suspension since November 2024 and that he had disciplinary records within the force, including reprimands and previous suspensions.
During the inquiry proceedings, the conduct attributed to Aciar was characterised as serious harm to the honour of the office and the institutional prestige of the Police. As an aggravating factor, particular account was taken of the impact that the facts had on the force's image.
To this disciplinary history was added the judicial record from the 2021 traffic incident, when Aciar was on duty at the 28th Police Station. According to the investigation, the officer was driving a motor vehicle when, at the intersection of Circunvalación Avenue and Salta Street, in the Capital, he struck Domingo Villafañe, 72 years old, who was riding a bicycle. Villafañe, a retired police non-commissioned officer, died days later from injuries sustained. For that incident, Aciar was charged with negligent homicide.
The final decision was adopted following the involvement of the various legal advisories of the San Juan Police, the State Secretariat for Security and Public Order and the corresponding legal bodies. The resolution of the inquiry determined the dismissal sanction, which entails the permanent separation of Aciar from the provincial police force.
