ZAMBOANGA CITY, Philippines — The student behind the deadly shooting at Ateneo de Zamboanga University acted alone, Interior and Local Government Secretary Jonvic Remulla said Thursday, as authorities increasingly focus on how the teenager gained access to firearms and what may have influenced him before the attack.
Remulla said investigators found no evidence that another person, organized group, family member or school-related conflict helped plan the August 18 shooting.
“Alone in the sense that he planned, executed, and willfully did everything on his own,” Remulla said, adding that authorities found no conspiracy behind the attack.
Investigators have reviewed the teenager’s social media activity and, according to Remulla, found no communications indicating that another individual or group participated in planning the shooting. Officials also said they had found no apparent evidence that religion, cultural differences or a dispute inside the school motivated the attack.
Investigators turn attention to online activity
While authorities say the student acted alone, questions over what influenced his behavior remain unresolved.
Remulla described the incident as involving “misguidance,” possible online influence and desensitization to violence. Authorities have been examining the teenager’s gadgets, gaming history and online conversations as part of their effort to establish a motive.
Earlier, Remulla raised concerns about online gaming communities and chat groups, including possible exposure through Roblox. However, authorities had not yet completed the forensic examination of the teenager’s devices when those comments were made, meaning any direct connection between a particular platform and the shooting has not been conclusively established.
That distinction is important: investigators are examining online influence, but there is currently no publicly established evidence that any specific video game or platform caused the attack.
How did the student get the guns?
The firearms have become another major focus of the investigation.
Reuters reported that investigators are looking into how the student obtained firearms belonging to his father, a Bureau of Customs employee. One of the weapons was reported to be a .40-caliber pistol issued through the Bureau of Customs.
The weapons used in the attack have also been linked by GMA News to the shooter’s father.
The case has intensified calls for stronger firearm-storage rules and tougher accountability for gun owners whose weapons become accessible to minors.
Remulla has urged Congress to revisit Philippine laws covering loose firearms and has called for tougher penalties, arguing that weak enforcement and easy access to firearms can have deadly consequences.
Shooter reportedly entered through emergency exit
Questions have also been raised about campus security, particularly how an armed student was able to enter the school.
Remulla said Ateneo de Zamboanga’s existing security procedures were consistent with industry standards and that school personnel appeared to have followed established protocols.
According to his account, classes had already begun at around 7:30 a.m. when the student entered the campus at approximately 7:50 a.m. through an emergency exit while security guards were positioned at the regular gates.
That finding could shift part of the broader discussion away from simply increasing guards at school entrances and toward securing secondary access points, emergency exits and other possible vulnerabilities.
Two students dead, several injured
Two students died in the August 18 attack: the Grade 8 shooter and another student who was shot inside the school.
Reuters reported that police corrected earlier information and identified the attacker as a Grade 8 student. Authorities said he was later found dead from a gunshot wound on the fifth floor, with evidence indicating that he took his own life.
GMA reported at least six people were injured, while earlier reports from other outlets carried different injury figures as information emerged immediately after the attack.
The incident was partly livestreamed using a body-worn camera, according to Reuters and AP, adding another disturbing dimension to the case and prompting renewed debate over how violent material involving minors spreads across social media.
Second deadly Philippine school shooting in two months
The Zamboanga attack came less than two months after another deadly school shooting in Tacloban City in June.
That earlier attack, also involving minors, intensified concerns about firearm access, youth violence, online influences and whether schools are adequately equipped to identify warning signs before violence occurs.
Education Secretary Sonny Angara has said the response cannot rely on tighter school security alone. He has urged families, educators and communities to regularly check on students and pay closer attention to behavioral and emotional changes.
Meanwhile, Senate President Sherwin Gatchalian has pushed for stronger restrictions on minors’ access to social media following the rapid circulation of graphic material connected to the Zamboanga shooting.
The bigger question
Remulla’s declaration that the teenager acted alone may answer one major question surrounding the attack: authorities currently see no evidence of a conspiracy.
But it leaves several others unresolved.
How did a young student gain access to powerful firearms? Were there warning signs in his online activity that could have been identified earlier? How was an emergency entrance used to bypass normal campus security? And what responsibility should gun owners, technology platforms, schools and families carry in preventing another tragedy?
Those questions are now likely to shape the national debate long after investigators determine the teenager’s precise motive.
For Philippine schools, the Ateneo de Zamboanga shooting is becoming more than an investigation into one student’s actions. It is emerging as a broader test of how the country addresses youth safety, responsible gun ownership, online exposure and vulnerabilities inside supposedly secure campuses.
