MANILA - Kian Loyd Delos Santos, whom police accused of peddling drugs in Caloocan City, sustained three fatal gunshot wounds to different parts of his body.

According to results of the autopsy conducted by the Public Attorneys Office (PAO) forensic laboratory, the 11th grader whose death has sparked public outrage, sustained a gunshot wound to his back, to the back of his left ear, and one inside his left ear.

The location of the gunshot wounds to his ears also showed that Delos Santos was on the ground when he was shot.

"Angulated 'yung trajectory ibig sabihin nakatayo lang yung shooter. Mukhang ang finishing shot 'yung tumama dito sa loob ng tenga. Napakalakas ng ebidensiya kasi sa likod ang tama sa parlance namin sa forensics mukhang intentional killing ito," Dr. Erwin Erfe, chief of the PAO Forensic Laboratory, explained.

There were also no indications that Delos Santos fought back, except for a wound on his stomach.

"Talagang magpafile po ng murder ang family. 'Pag binaril ka ng talikuran treacherous po yun. Kaya dun po sa mga involved na pulis mabuti po ay sumuko na kayo sa batas," PAO Chief Atty. Persida Rueda Acosta said.

Erfe also questioned the location of the gun allegedly used by Delos Santos to fire at cops.

The gun was found near Delos Santos' left hand but the boy was right-handed.

"Imposible na ikaw ay right handed ay pumutok ka sa left hand unless ikaw ay trained shooter o law enforcer ka na napag-aralan mo na pumutok ka using your non-dominant hand," Erfe explained.

The PAO Forensic Team also want to get the clothes Delos Santos was wearing when he died for further examination, since he sustained a gunshot wound to the back.

"From the clothes makikita natin kung malapitan kasi nandun yung ebidensiya nandun yung pulbura kung magkakaroon ng hearing masa-subpoena mai-examine natin," Erfe added.

Delos Santos was killed in an alleged shootout with law enforcers during the bloodiest week of the government's anti-narcotics drive.

The chief of the Philippine National Police, Director General Ronald dela Rosa, said on Sunday Kian delivered drugs for his father and uncle and presented to media a professed pusher who claimed to have had transactions with Kian.
