MANILA (UPDATE) - The Philippine National Police (PNP) on Monday dismissed from service Police Staff Sgt. Jonel Nuezca, the suspect in the brutal killing of a mother and son in Paniqui, Tarlac last month.

In a press briefing, PNP chief Police Gen. Debold Sinas announced Nuezca's dismissal, which came 3 weeks after the police officer was caught in a now-viral video shooting his unarmed neighbors.

"That's it. That completes the cycle of investigation involving ex Police Staff Sgt. Jonel Nuezca," said Sinas who earlier vowed to fast-track Nuezca's ouster from service.

Nuezca was slapped with administrative charges that include grave misconduct for the twin slay. He was formerly assigned at the Parañaque police crime laboratory.

During an arraignment for his criminal case on Jan. 7, Nuezca entered a not guilty plea for the 2 counts of murder, according to Paniqui Municipal Police Station chief Noriel Rombaoa.

Due to a dispute over a holiday noisemaker, Nuezca shot to death mother and son - Sonia Gregorio, 52, and Frank Anthony Gregorio, 25 - in Paniqui town on Dec. 20. The incident was caught on video and went viral on social media.

The attack drew widespread condemnation, with some officials calling for reforms in the PNP and netizens pleading to stop the killings.

The victims were laid to rest at the Paniqui Garden of Angels Memorial Park on Dec. 27. Meanwhile, Nuezca had been transferred to the custody of the Bureau of Jail Management and Penology.
