Ex-PNP chief suggests drug use may have driven Tarlac cop's deadly shooting

Two civilians, a mother and son, were fatally shot by an off-duty police officer during a dispute over a noisemaker.
Why would you avoid drug testing if you're not an addict?
Former PNP chief Dela Rosa speculating about the officer's possible substance use based on his refusal of mandatory testing.

In the days before a new year, a dispute over a traditional noisemaker in Tarlac became the occasion for an act of irreversible violence — an off-duty police officer drawing his weapon against unarmed neighbors, a mother and her son, and ending their lives. The killing was recorded and witnessed by the world, forcing a reckoning not only with one man's choices but with the deeper question of what happens when those entrusted with public safety become the source of public harm. The case now moves through the machinery of justice, carrying with it unresolved questions about the officer's history, his state of mind, and the systems that may have failed to catch the warning signs.

  • A neighborhood argument over a New Year noisemaker ended in two deaths when off-duty officer Jonel Nuezca drew his weapon and shot mother and son Sonia and Frank Anthony Gregorio.
  • The killing was captured on video and spread rapidly across social media, transforming a local tragedy into a national crisis of accountability for the Philippine National Police.
  • Former PNP chief Dela Rosa publicly accused Nuezca of being under the influence of drugs, pointing to his prior refusal of mandatory drug testing as damning evidence of a hidden addiction.
  • Post-arrest drug tests returned negative, undercutting Dela Rosa's theory while leaving the question of what truly drove Nuezca's lethal decision-making uncomfortably open.
  • Nuezca is now in custody facing two murder charges, with Dela Rosa calling for the death penalty and the case casting a long shadow over public trust in law enforcement.

A Tarlac police officer shot and killed two neighbors — a mother and her son — over a dispute about a boga, a traditional Filipino noisemaker used during New Year celebrations. Jonel Nuezca, 46, opened fire on Sonia and Frank Anthony Gregorio as the confrontation escalated, and someone nearby recorded the entire incident. The video spread across social media almost immediately, and within a day Nuezca had been charged with two counts of murder.

What followed was a portrait of an officer with a troubled record. Nuezca had previously faced administrative charges for refusing mandatory drug testing — a requirement for all PNP personnel. Former PNP director Ronald Dela Rosa seized on this detail during a televised interview, arguing that Nuezca's behavior bore the hallmarks of someone whose judgment had been chemically compromised. "Why would you avoid drug testing if you're not an addict?" he asked. The implication was pointed and public.

But the theory found an obstacle: after his arrest, Nuezca tested negative for illegal drugs, according to PNP Chief General Debold Sinas. The result did not fully close the door on whether substance use had played a role in the period before the shooting, but it complicated the narrative Dela Rosa had put forward.

What no one disputes is the character of the act itself. Dela Rosa called it cold-blooded murder — a killing without provocation, carried out by a man who happened to be armed and off-duty during a neighborhood quarrel. He has called for the death penalty. Nuezca remains in custody, the video evidence unambiguous. Two people are dead, and the community is left to confront the unsettling truth that the man who killed them was sworn to protect them.

A Tarlac police officer shot and killed his neighbors—a mother and her son—over a New Year's noisemaker, and the killing was captured on video. The incident has drawn scrutiny not just for its brutality but for what it may reveal about the officer's state of mind.

Jonel Nuezca, 46, opened fire on Sonia and Frank Anthony Gregorio after a dispute erupted between them over a boga, a traditional Filipino noisemaker that becomes especially common during New Year celebrations. The confrontation escalated quickly enough that someone was there to record it. The video spread across social media, and within a day Nuezca was charged with two counts of murder.

What has emerged since then is a portrait of an officer with a troubled history. Nuezca had previously faced administrative charges for refusing to submit to mandatory drug testing—a requirement for all police personnel. That refusal alone raised questions. Ronald Dela Rosa, the former director of the Philippine National Police, suggested during a Wednesday morning interview that Nuezca's actions may have been driven by drug use. "Why would you avoid drug testing if you're not an addict?" Dela Rosa asked rhetorically on air. He went further, arguing that the officer's decision-making capacity was likely compromised by narcotics, and that the killing itself bore the hallmarks of someone whose judgment had been chemically altered.

The theory, however, rests on incomplete ground. When Nuezca was tested after his arrest, the results came back negative for illegal drugs, according to PNP Chief General Debold Sinas. That finding contradicts Dela Rosa's inference, though it does not necessarily resolve the question of whether substance use played a role in the days or weeks leading up to the shooting.

What remains undisputed is the nature of the act itself. Dela Rosa characterized it as cold-blooded murder—a killing without provocation, without justification. The victims had done nothing to warrant lethal force. An off-duty officer, armed and present during a neighborhood dispute, chose to use his weapon. Dela Rosa has called for the death penalty in the case, a position that reflects the severity with which he views the crime.

Nuezca sits in custody facing murder charges. The video evidence is stark. The question of what drove him to pull the trigger—whether drugs, rage, poor judgment, or some combination of factors—remains partly open. What is certain is that two people are dead, and a community has been forced to reckon with the reality that the person who killed them wore a police uniform.

Why would you avoid drug testing if you're not an addict? The officer's decision-making was likely affected by narcotics.

The killing was cold-blooded, with no provocation from the victims. Nuezca deserves the death penalty.

Why did Dela Rosa focus so heavily on the drug angle when the test came back negative?

Model

Because the refusal to test itself seemed like an admission. In police culture, you don't dodge that kind of order unless you have something to hide. The negative result later complicated his theory, but by then the narrative was already out there.

Inventor

Do you think drugs actually had anything to do with it?

Model

We don't know. The negative test suggests maybe not—or maybe he was clean by the time they tested him. But Dela Rosa's real point wasn't medical; it was about judgment. He was saying something broke in Nuezca's mind, and he was guessing at the cause.

Inventor

What about the boga itself? That's such a small thing to kill over.

Model

That's the part that haunts it. It's a noisemaker. Kids use them. The fact that it escalated from that to gunfire tells you how quickly things fell apart, or how ready Nuezca was for violence.

Inventor

Did anyone defend him?

Model

Not really. Even Dela Rosa, who's a former cop, called it cold-blooded. There's no ambiguity in the video. He shot them. They died. The only real question left is why he did it, and we may never have a clean answer to that.

Inventor

What happens to him now?

Model

Murder charges, trial, and Dela Rosa wants capital punishment. Whether the courts agree is another matter. But he's not walking free.
