KORONADAL CITY: South Cotabato 2nd District Rep. Peter Miguel has offered a PHP1-million reward for information leading to the identification and arrest of those responsible for the murder of Tantangan vice mayoral aspirant Jose Osorio. Miguel announced the reward Monday afternoon, as police continue to search for leads in the case. According to Philippines News Agency, the South Cotabato Police formed a Special Investigation Task Group (SITG) on Tuesday to expedite the investigation into Osorio's killing on the evening of Nov. 17. Osorio, a former barangay chairperson and candidate for vice mayor in next year's elections, was found dead early the following morning in a pool of blood at his family's roadside eatery in Barangay Bukay Pait. Col. Samuel Cadungon, South Cotabato police director, stated that the SITG-Osorio will focus on identifying and charging both the attackers and the mastermind. Relatives of the 58-year-old victim mentioned that Osorio had no known enemies. The police are considering pers onal grudges or election-related motives as possible angles in the investigation. Cadungon also noted that Osorio had not received death threats prior to the attack. Initial findings revealed that Osorio's wife and their house help had not heard gunfire around 10 p.m., when the killing was believed to have occurred. Osorio was the running mate of former Mayor Benjamin Figueroa in the upcoming elections and had served three terms as chairperson of Barangay Bukay Pait.
