Mariana Domínguez died last Christmas, after being hit in the head by a projectile in the Mendoza town of Godoy Cruz. The provincial Ministry of Security and Justice is now offering more than two million pesos to find the person responsible for the incident.

So far this year, this is the second time they have asked for information in exchange for financial compensation. In January the figure was 1,651,000 pesos. "The payment of the reward offered will be subject to the quality of the data provided that leads to the appearance of the author," the ministry detailed.
