MANILA – The shooting incident in the Ateneo de Manila University that left 3 dead and 1 injured on July 24 is an isolated case, the Philippine National Police (PNP) said Monday.

Former Lamitan, Basilan Mayor Rose Furigay and her long-time aide Victor Capistrano were killed when doctor Chao-Tiao Yumol opened fire ahead of the Ateneo Law School’s graduation ceremony.

A security guard named Jeneven Bandiala was also killed. Furigay’s 25-year-old daughter Hanna Rose was wounded.

Medina said they found that Yumol has been in Metro Manila for quite some time already.

“According to him, he had got a, he rented an apartment, and then later on he transferred to hotel,” Medina noted.

The policeman also noted that they confiscated 2 guns from the suspect.

“When we accosted him in a public transport vehicle, we’re able to recover two (calibres) of firearms, so one 9mm Ruger and one 45 Llama, and [he] had with him several rounds.”

Medina said the Yumol had a license for the Ruger, but they are still looking for the Llama's registration documents. He said the assilant had placed the guns in a bag which was not inspected, enabling him to pass through the university's security checks.
