Tests on the stains found Saiful's DNA on the two stains on Saiful's trousers, while on the underwear, a stain contains Saiful's DNA while the other contains the alleged victim's DNA and another unknown male contributor, dubbed Male Y. While the DNA of Male Y was found on all four cotton buds retrieved from Saiful's anus, it was one of them which possessed DNA from another unidentified male which is raising eyebrows. The cotton bud in question is B5 which was retrieved by the Hospital Kuala Lumpur doctors from Saiful's peri-anal area.
Seah, in replying to questions from DPP Noorin Badaruddin in the afternoon, said the DNA profile derived from B5 consisted of a mixture of male-origin DNA profiles. It is concordant with the profile of blood stain specimen B10 (Saiful's blood sample), the Male Y and one other male contributor, she said.
Explaining her findings on Appendix 1 under the Summary of STR results, Seah, who has been with the Chemistry Department since 1991, said B5 is a non-sperm extract. She said it contains readings of Saiful's DNA string, Male Y DNA string and that of another unidentified male. All these tests, she said, are done through an electropherogram (DNA sequencing) machine.
When asked by DPP Noorin as to how it was possible to have th! ree DNA samples, Seah said this could have been as a result of 'touch DNA' whereby Saiful may have sat on a toilet seat. This could be possible... it may require a 'touch' for someone's DNA to be transferred. However, I agree I am no expert in this. Seah also said she could not answer as to how long such a seminal stain can last in one's rectum, as she was not a medical expert.
Dominant 'Male Y'
Seah also testified that her findings and DNA analysis from the sample taken from the cotton bud revealed that Male Y is the dominant. The sperm extract conducted on B7 (high rectal swab) showed the dominance of Male Y. Similar findings were made on the second semen stain found on Saiful's grey underwear, she said. Seah also testified that no DNA profiles were retrieved from swabs B, B1, B2, B3, B4 and B6.
The chemist has yet to testify on two other swabs namely B8 and B9, where DNA analysis was also performed after finding traces of semen. B8 was retrieved from the higher rectal area while B9 is from the lower rectal area. What the prosecution is trying to prove today is that the presence of the Male Y DNA inside the rectum is proof of sodomy.
Earlier in the trial, the HKL doctors testified that a seminal stain can stay in the rectal area for 72 hours. They had also testified that following traces of semen stains in the anus from the Chemist's Report, they adduced that penetration and sodomy had taken place. The hearing was put off earlier when it was discovered that the DNA charts which were provided to the defence before the trial were not ample. This was clarified with Anwar's specialist, Dr Brian McDonald, who was also present to assist the defence team.
Hearing continues with Seah's continued testimony.
'Air mani 'lel! aki Y' d itemui pada seluar Saiful'
3 sampel DNA lelaki,satu dikatakan dominant Y dan yang satu lagi diistilah sebagai 'touch DNA' Hari baru aku kenal dan belajar perkataan baru 'Touch DNA' .
DNA Saifool dikesan pada seluar dan seluar dalamnya. Kalau Saifool diliwat,kenapa DNAnya berada pada seluar dan seluar dalamnya? Kemungkinan besar DNAnya itu diletakkan di seluar dan seluar dalamnya oleh orang2 tertentu....
"Seah said this could have been as a result of 'touch DNA' whereby Saiful may have sat on a toilet seat." Buat apa Saifool duduk di atas 'toilet seat', sedangkan dalam keterangan awal Saifool kata dia tak berak 2 hari....
Plot dah menjadi lintang pukang....
