Investigator PO3 Erron Balauat of the Taguig police Criminal Investigation Division identified the fatality as Mario Osorio, a resident of Block 6, Lot 8, Barangay Upper Bicutan, Taguig. Osorio died as he arrived at the Ospital ng Makati with a single gunshot wound in the head. His stepdaughter survived.
Based on the investigation of the Taguig police, the incident took place at around 6 p.m. inside the residence of Osorio.
Investigation said Osorio had a spat with his 19-year-old stepdaughter Nerissa Billones who had informed him that she was having a boyfriend.
Unable to contain his jealousy, Osorio took out his 9 mm pistol and shot his stepdaughter once in the body.
After the shooting, Osorio reportedly proceeded to the Taguig police Traffic Enforcement Group office to surrender himself and report the shooting.
However, before policemen were able to confront Osorio, he again took out his pistol and shot himself in the head.
Billones was brought to the Makati Medical Center where she is currently recovering from a bullet wound. – Marvin Sy
