Bandar Seri
Begawan - An Australian DNA expert has strongly questioned the
local method of collecting blood samples and other evidences at the
scene of crime.

Mr Brian Leslie McDonald, a
consultant Molecular Geneticist working on DNA testing for
forensic and diagnostic matters, was giving evidence in the Brunei
High Court yesterday during the trial of Richard Chia Kok Hong,
53, a car salesman accused of murdering a family of three. He is
denying all charges.
The case involves the brutal
killing of Maul bin Jambu, 44, a Royal Brunei Airlines mechanic,
his 37-year-old schoolteacher wife, Seniwati binte Untong, and
their adopted daughter Neena Asmira, aged 2, on the night of
December 15, 2004 or early next morning at a bungalow in Serusop,
in the capital's suburb.
The child was smothered to death
with a pillow while the two were mercilessly beaten to death.
Mr McDonald was produced in court
by the defence. |

The Prosecution is basing their
charge on Richard's DNA found on the two victims and blood found
in his wife's car and to prove their case they produced three
overseas experts, Mr Andrew Parry from the UK, Ms Cheong Poh-Yee
and Ms Ang Hwee Chen both from Singapore previously.
The Brunei government
pathologist, Mr Telesinghe, also testified. But their expert
testimonies were challenged in court when Mr Siva Sankaran,
defending, examined Mr McDonald. |
He said the amount of DNA tested was
below the threshold for the quantisation system used in the tab.
The Prosecution had adduced evidence
indicating that Richard was driving his wife's car at the time of the
crime and bloodstains belonging to Maul and Seniwati were found in it.
Richard has denied using his wife's
car that night. Mr McDonald contented that clearly the crime scene had
large amounts of the deceased woman's blood, which could readily be
transferred from anyone attending the scene of the murders and
subsequently examining the car.
A number of persons could fit these
activities and it appears at least some person or persons from the
investigation team have had contact with blood and or items with blood
on them at the scene.
All conclusions regarding the DNA in
this matter which has the effect of implicating Richard relies
absolutely on the correct collection, handling, storage and testing of
the fingernail items and items collected from the car, the expert
testified.
Should the integrity of any of the
proper steps be in doubt then any conclusions are also in doubt; he
declared in court.
The unexplained change in the
integrity of the fingernail scrapings together with unsealed,
accessible envelopes and inconsistencies with regards to the DNA
testing provide opportunities and indications that errors may have
occurred with these items.
It is surprising that the fingernail
samples were not sent to Singapore at the same time as the reference
samples from the deceased and the glove and car samples were sent on
December 30, 2004, Mr McDonald stated.
The results of testing the car would
also be completely explained by an inadvertent transfer by crime scene
investigators. At least some of whom appear to have become
contaminated and transferred blood and possibly other DNA material in
or around the crime scene. This transfer may also have been away from
the crime scene particularly if they were unaware of the presence of
the blood or other material adhering to them or their clothes, he
added.
Given the minute amounts of material
required to produce the results obtained by the labs, there exists a
real possibility of contamination given the evidence in this case, the
expert witness told Chief Justice Dato Mohd Saied and Justice Dato
Steven Chong.
Prosecution is led by Deputy Public
Prosecutor Haji Yusree and assisted by DPP Pengiran Nina Jasmine.
Awang Yusof Halim and Siva Sankaran are defending. Hearing continues. --
