Authorities have traced the firearms used by the students involved in the shooting at San Jose National High School in Tacloban City on Monday, June 22, 2026, that killed three students and injured 11 others.

In a report by GMA’s 24 Oras, police said one of the firearms was traced to a policewoman while the other was linked to a security agency in Cebu City.

Police said the suspects, 14 and 15 years old, used a caliber .38 revolver and a 9mm Glock pistol, and randomly fired shots while the class was ongoing.

Investigators added that the minor suspects fired their guns about 40 times, based on initial investigation.

“Diretsong pumasok yung dalawang CICL natin. Without saying anything basta na lang po nagpaputok. Nandoon pa lang daw sa bintana ay nagpaputok na sila,” PNP Spokesperson, Col. Allen Rae Co, said.

Investigation also showed that the 9mm pistol used by the 14-year-old suspect is owned by his aunt, a police officer assigned to Police Regional Office 8.

Police said the policewoman is now under investigation and placed under PNP custody.

“The subject policewoman is now under investigation and placed under custody of the regional police office. If proven that they were remiss in the custody and safekeeping of their firearms they will be charged accordingly,” Co said.

On the other hand, the .38 caliber firearm used by the 15-year-old suspect was traced as registered to a security agency in Cebu City.

Police are still looking into which security guard the firearm was issued to, specifically.

Authorities are also investigating whether school authorities took any action as one of the gunmen had reportedly been posting violent videos and clips of gunfire on social media prior to the shooting.

“Ito ay very obviously red flags. If the school authorities or anybody, we are not putting blame on anybody, but if anybody was able to monitor itong mga red flags na to, this could have been prevented,” Co said.

Police are also investigating whether the two students may have been imitating school shootings in the United States, which prompted the police to order tighter security measures in schools.

“That is why one of the interventions that I mentioned in our earlier press conference is to limit the exit and entrances of all schools to better control yung pong ingress and egress ng ating mga estudyante. We are really alarmed and we are doing everything that we can para po matuldokan na itong mga instances,” Co said.

Investigators said the incident may have stemmed from personal grudge allegedly rooted in school bullying.

“We are still verifying kung exactly the targets were in that classroom, but as I have said earlier this could be connected to a bullying incident,” Co added.

The minor suspects, both considered children in conflict with the law (CICL), are now under police custody.

Meanwhile, the Department of Justice (DOJ) has already coordinated with prosecutors in Region 8 to determine the facts surrounding the incident.

“The Department will allow law enforcement authorities and the prosecutors concerned to complete their investigation…We will release further information once the facts have been sufficiently ascertained and are proper for public disclosure,” DOJ Spokesperson, Atty. Polo Martinez, said.
