Police Staff Sgt. Jonel Nuezca, the ‘killer cop’ in the brutal Tarlac slay, is asking for a favor when he spoke to a high-ranking police official.

“Sir, sana matulungan niyo po ako,” Nuezca told Police Regional Office 3 chief Brig. Gen. Val de Leon in a video that ABS CBN News got hold of.

The words of the murder suspect, however, did not sit well with the police chief.

Brig. Gen. De Leon responded, “Anong pang matutulong naming sayo? Wala na. Sinira mo ang buong imahe ng PNP.”

Nuezca said, “Sir para sa pamilya ko nalang po.”

He told de Leon that he regrets the sudden outburst of his emotion in the incident that turned fatal.

“Sir, inaamin ko po yung pagkakamali ko. Sobrang emosyon. Nagsisisi po ako sa ginawa ko. Laking pagsisisi, Sir, unang una para sa pamilya ko, Sir,” Nuezca said.

He has been charged with two counts of murder for the brutal killing of Sonya Gregorio and her son Frank over the use of ‘boga’, an improvised canon-like noisemaker.
