McDonald, who is the fourth defence witness, testified yesterday that chemist Dr Seah Lay Hong's testing was not according to international standards following errors in labelling and not swiping the sample on a receptacle.
This follows the discovery that two out of 10 samples having faulty labels when it was stated on the container that they were taken on June 26, 2008.
This was despite that the medical examination was done on the alleged victim, Mohd Saiful Bukhari Azlan, on June 28.
On Dr Seah
McDonald says you cannot assume Saiful's sperm is in his own rectum.
McDonald says, "We cannot discount Saiful's sperm was up in his own anus."
"I would say Seah's evidence is a guess."
McDonald also testified such incompetence behaviour could have resulted in the chemist being “sacked” from his or her job.
On Nor Aidora Saedon.
“If these tests were done in school, she’d have failed them” Dr McDonald said of chemist Nor Aidora Saedon.
The Judge should throw out this case and I guarantee he will have a blessed Hari Raya…..otherwise it will be shameful to appear in public and in open houses!
