MANILA—The 3-year-old girl who died in a publicized anti-narcotics operation in Rodriguez town, Rizal, sustained a gunshot wound in her brain, authorities said Tuesday.

Myka Ulpina reportedly died after a bullet entered her nape with an upward trajectory and then exited her left ear.

“Entry wound niya sa batok, lumabas siya sa may tenga, mas mataas sa may tenga. So lumalabas, pataas,” Philippine National Police-Crime Laboratory director CSupt. Rolando Hinanay said.

“Depende sa position ng bata at position ng nakabaril. Lumalabas sa result ng examination from the nape o sa batok, lumabas ang bala sa tenga. Kung downward o upward, depende sa position ng bata.”

The child reportedly also had gunshot wounds in her foot and hand.

Hinanay said the findings did not yield any metal fragments or bullet pieces in Mica’s body, which makes it hard for them to determine who among the operatives killed her.

“Hindi natin ma-determine kung sino ang nakabaril dahil wala tayong nakuha na fragments or pieces ng bullet doon sa katawan ng bata para ma-i-match natin doon sa mga baril na nakuha sa crime scene o gamit ng mga pulis,” he said.

Hinanay noted the measurement of the gunshot wounds matched the size of the 9-mm bullet submitted by police operatives.

“Noong matagpuan ng SOCO (scene of the crime operatives) ’yung tatay, lying face down, may nakitang caliber .45 sa tabi ng bangkay niya,” the director said.

Authorities are still investigating the child's death.

Myka was killed June 30 after being caught in the crossfire during a police operation. Her father Renato also died, along with an undercover cop.

The police said Renato fired at the police and used Myka as shield. The child’s mother belied this.

New York-based Human Rights Watch slammed Myka’s death, noting that police accounts of drug raids “are not reliable because the officers enforcing the “drug war” have been shown to manufacture evidence.” - Maan Macapagal, ABS-CBN News
