BUREAU of Corrections spokesperson Gabriel Chaclag on Wednesday confirmed the death of former Parañaque policeman Jonel Nuezca, the off-duty cop who was caught on mobile video shooting to death a mother and son over an altercation involving a homemade canon in Tarlac province last December 2020.

In a message, Chaclag said Nuezca was brought unconscious by his cell mates at the New Bilibid Prison in Muntinlupa at 6:30 p.m. on Tuesday to the prison infirmary.

They noticed that Nuezca had collapsed on the floor of their dormitory, Chaclag said.

Chaclag said that a full-blown investigation is now underway to determine if there was foul play in Nuezca’s death.

Nuezca’s remains will undergo autopsy, he continued.

The former policeman was convicted by the Paniqui, Tarlac regional trial court of two counts of murder over the deaths of 52-year-old Sonya Gregorio and her son Frank Anthony Gregorio, 25, in Purok 2, Barangay Cabayaoasan, Tarlac.

Nuezca was also ordered to pay the heirs of the victims P952, 560 in damages.

The court said the prosecution was able to establish treachery during trial on the merits of the case.

The incident stemmed over an altercation involving homemade PVC canon “boga”.

Nuezca fled after shooting the victims, but surrendered to the Rosales Pangasinan Municipal Police Station hours later. He also turned over his service pistol that was used during the crime.

Nuezca and the Gregorios are residents of Purok 2 in Barangay Cabayaoasan, Paniqui.

The two families were allegedly involved in a property right-of-way dispute, but the shooting incident stemmed from the firing of a PVC cannon or “boga” by the Gregorios.

The shooting incident was caught on camera and the video is now viral on social media.

Netizens are seeking justice for the Gregorios, calling for the end of police brutality and impunity in the Philippines.
