THE assailant of a 72-year-old retiree who was found stabbed at
his Toa Payoh Central flat almost three years ago remains at
large.
A daughter of Mr Koh Sam Hong alias Koh Sam Yak had found his
naked body with a knife embedded in the back in his bedroom when
she returned home at about 10.45pm on July 31, 2008.
He died from excessive blood loss from a stab wound to the
aorta. At an inquest into his death on Thursday, an investigation
officer told the court that when Ms Koh returned to the four-room
flat, the main gate and wooden door were closed but not locked.
Her haversack and a faulty mobile phone were missing from her
room.
Forensic examination showed the DNA profile of an unknown person
but he was untraced to the DNA database.
Extensive investigation and inquiries were conducted with no
tangible results, the court heard.
