KUANTAN: A doctor, attached with Tengku Ampuan Afzan Hospital (HTAA), told the court here yesterday that excess blood samples from tourist Stephanie Foray's mother and sister were disposed of as they were a bio-hazard.
Dr Fong Chee Hai, in replying to questions raised by the defence at the murder trial of Foray, said they were disposed of as they were no longer needed and necessary blood samples had already been taken.
The 28-year-old took the stand on the eighth day of the proceedings.
Asked by defendent Asni Omar's counsel, Datuk Ng See Teong, on what he did with the remaining blood samples taken from the victim's mother, Irene Mortel, and sister Vanessa Foray for Deoxyribonucleic acid (DNA) tests on Aug 12 last year, Dr Fong said they were thrown into a "sharp bin", which was meant for clinical waste.
He said it was his own decision to throw the remaining blood samples after filling in the four columns on the fast technology for analysis (FTA) card.
When re-examined by deputy public prosecutor Salim Soib @ Hamid, Dr Fong explained that the remaining samples were a bio-hazard and and should be destroyed if they were no longer needed.
Earlier, Dr Fong told the court that he and forensic assistant Aliah Jusoh had taken all necessary precautions before taking the blood samples from Mortel and Vanessa at 1.30pm on Aug 12.
The doctor said he was aware that one should avoid coffee or tea some four hours before blood samples were taken. However, he did not stop Mortel and Vanessa from taking such beverages prior to having their blood samples taken.
"This means both of them (Mortel and Vanessa) did not take any precautionary measures, which were required under the standard operating procedures (SOP) for the DNA test?" asked Ng.
To this, Dr Fong replied he was unsure but agreed that it might affect the DNA test results.
The doctor had earlier identified an envelope which contained Vanessa's blood samples, but could not identify another one as it was in bad condition.
Although the first envelope was dirty, he could still read the information on it while the second envelope, which supposedly contained Mortel's blood samples, was in bad condition.
Dr Fong said when the envelopes were handed over to the police, they were white in colour and had labels on them, containing relevant information.
When asked by defence counsel Mohd Hisham Abdul Rahim whether the same FTA card could be reused to test other samples, Dr Fong said he was unsure and said that only a chemist could give an accurate answer.
Judge Datuk Mariana Yahya later fixed the next hearing date from June 12 to 22.
When met outside the court, Vanessa said she and her parents would return to France in the next few days and had yet to decide whether to attend the next hearing.
"But we will definitely return to Kuantan before the sentencing."
Asni is charged with murdering Foray at an unnumbered house in Kampung Tekek, between 8pm on May 10 and noon, on May 12 last year.
