DNA evidence now admissible in court

- Delon Porcalla -
Convicted rapist Gerrico Vallejo thought he would be acquitted on appeal, but the Supreme Court upheld his death sentence based on DNA evidence that he raped and killed a nine-year-old girl in 1999.

In affirming Vallejo’s conviction, the high tribunal ruled that the result of DNA testing – a scientific technique of identifying the genetic code of an individual –is now admissible as evidence in all courts of law nationwide.

"Taken together with the other circumstantial evidence, especially the DNA profile found in the vaginal swabs taken from the victim which matched the DNA profile of Vallejo, prove beyond reasonable doubt Vallejo’s guilt," read part of the tribunal’s decision.

Using DNA or deoxyribonucleic acid, the US Supreme Court has set free 80 death convicts after evidence showed that they were not guilty of the crime they were accused of committing.

The uniqueness of an individual’s DNA — which contains his genetic code or profile — much like a fingerprint, can identify one person from another.

The Supreme Court threw out the arguments of Vallejo’s lawyer that DNA was a "mere junk science" because the basis of his client’s conviction was an "unreliable" tool.

"This generalization about the state of DNA science in the Philippines, like Vallejo’s fulmination against hardened policemen who leave no marks of torture on their victims, is without any basis," read the decision.

Last May 9, the Supreme Court en banc affirmed the 2000 decision of Judge Christopher Lock (now deputy court administrator) of the Cavite Regional Trial Court, for Vallejo to pay his victim’s heirs in the amount of P100,000 as civil indemnity and P50,000 as moral damages.

"Among the evidence which established the guilt of Vallejo was the DNA analysis done by the National Bureau of Investigation on the vaginal swabs collected from the victim and found to have DNA profiles of Vallejo," read a statement from the Supreme Court public information office.

During trial, Vallejo said police forced him to produce the blood-stained clothes which he was said to have used in raping his victim.

Vallejo’s blood type ("O") matched those on the clothes after the NBI took blood samples from him when they were investigating his involvement in the crime.

But the Supreme Court said Vallejo failed to prove that policemen tortured him and that a search warrant was no longer needed then because he had allowed police to search his house.

Court records showed that at around 1 p.m. on July 10, 1999, the victim went to the house of Vallejo’s sister who was her tutor.

After an hour, the victim went out with Vallejo, who was staying at the same house, to look for a book which she could use for a school project.

They later returned to the house of Vallejo’s sister after they had found the book.

When the victim’s mother woke up at 5 a.m. without finding her daughter, she went to the house of Vallejo’s sister but was told that the victim had already left.

The victim’s mother searched for her until early morning the following day.

At 10 a.m., she was informed that her daughter’s dead body had been found tied to the root of an Aroma tree by the river bank, with her sleeveless shirt tied around her neck.

After barangay officials picked up Vallejo and took him to the barangay hall, the victim’s mother pointed to him as a suspect because he was the last person seen with her daughter.
