KUALA LUMPUR: A chemist told the High Court yesterday of the presence of semen belonging to “male Y” from one of two seminal stains lifted from an underwear belonging to main complainant Mohd Saiful Bukhari Azlan.
Dr Seah Lay Hong of Chemistry Department headquarters in Petaling Jaya also confirmed the presence of semen belonging to “male Y” on four swabs with the first swab from para-anal region, two from high rectal areas and one at low rectal area of the complainant.
The chemist who is attached to the department since 1991, however did not name nor identify “male Y” in her report.
She said no seminal stains of “male Y” were found on the multi-coloured carpet and a duvet seized from the room of a condominium unit where the alleged offence was committed.
During examination-in-chief by deputy public prosecutor Noorin Badaruddin, Dr Seah said she also carried out tests on two long-sleeved shirts and a dark blue underwear on the request of investigation officer DSP Judy Blaucious Pereira.
The fifth prosecution witness told the court results from the exhibits were negative from any presence of semen belonging to
“male Y”.
“However, two seminal stains found on a pair of black trousers belonging to Saiful, confirmed it belongs to the owner,” said Dr Seah.
The chemistry report tendered as exhibit also revealed that sample B5 taken from para-anal area consisted of male DNA of Saiful, male Y and another unidentified male contributor.
When asked to explain the scientific method she carried out before preparing her report, Dr Seah explained in detail on the DNA (deoxyribonucleic acid) testing using the multiplex polymerase chain technique.
Anwar, 63, is charged with sodomising Saiful, 25, his former personal aide, at Unit 11-5-1 of Desa Damansara Condominium in Jalan Setiakasih, Bukit Damansara, between 3.01pm and 4.30pm on June 26, 2008.
Questioned further by Noorin how long seminal stain specifically spermatazoa could remain to facilitate DNA testing, Dr Seah said humidity plays a crucial role.
“If it is exposed to dry and cool weather, then it is possible to remain for a considerable time,” said the chemist.
To another question by Noorin on how long semen could remain in the body in case of sodomy, Dr Seah said that it was not her expertise since her work was more confined to carrying out laboratory examination.
Earlier, she said that she first received 12 envelopes containing 12 exhibits marked B to B11 on June 30, 2008 from DSP Pereira and followed by six more envelopes and two packages on July 1, 2008.
Australian DNA expert Dr Brian Mcdonald was present in court to assist the defence team.
Hearing before justice Datuk Mohamad Zabidin Mohd Diah resumes this morning. — Bernama
