SINGAPORE - On the day he was questioned over the disappearance of a 31-year-old woman, Leslie Khoo Kwee Hock led police on a futile search at Gardens by the Bay East.
He claimed he had left her there after pushing her so hard that her head "hit the cement".
Hours later, after he was allowed to speak to his wife and to make a video call with his son, Khoo told investigators that he would take them to Lim Chu Kang, which turned out to be the place where he had burned the body of senior engineer Cui Yajie over three days.
On Friday (March 15), the fourth day of Khoo's murder trial, the evidence before the High Court centred on the investigation into Ms Cui's killing and efforts to recover her remains.
The court heard that after Khoo revealed where he had burned the victim's body, the reservoir at Sungei Buloh Wetland Reserve was drained in an attempt to find her remains.
Clumps of hair, pieces of partly burnt fabric and a bra hook were all that were recovered from the site.
Khoo had told police that he had moved the body into a small drain nearby. This drain leads to a monsoon drain, which leads to the wetlands reserve, the court heard.
Deputy Superintendent Tan Lian Heng told the court that after the reservoir was dammed up and water extracted, investigators scoured the exposed ground.
Multiple bone-like structures were recovered but these were later determined not to be human remains.
On July 25, five days after Khoo's arrest, he led a team of investigators to retrace his steps.
At Marina Gardens Drive, a quiet road near Gardens by the Bay, he described how he had strangled Ms Cui in his car after she threatened to "let everyone know" what a bad man he was.
Khoo told DSP Tan he was so angry with Ms Cui that he "bit his teeth" and used one hand to grip her neck before using the other as well.
He also led the officers to a minimart at Canberra Link, in Sembawang, where he bought charcoal on the night of July 12, and to two shops on Kranji Road where he bought charcoal and kerosene on July 13.
Khoo also led investigators to D'Kranji Farm Resort, in the Lim Chu Kang area, where he had checked into a room on July 13, and Jalan Selimang in Sembawang, where he said he threw Ms Cui's ashes into the sea.
They also went to Orchid Country Club, where he threw her handbag, mobile phone and wallet into a waste bin on July 14.
The court also heard that police determined from surveillance footage that Ms Cui was last seen alive wearing a multi-coloured dress from label Love, Bonito.
As the dress was sold out, the police obtained two dresses from people who had bought it, to be compared with the pieces of fabric.
In court on Friday, Khoo nodded his head emphatically and confirmed that this was the dress she was wearing at the time.
Superintendent Roy Lim, who interviewed Khoo on July 20, said he continued questioning the laundry shop manager after the fruitless search at Gardens by the Bay East.
Khoo asked to speak to his wife, saying he wanted to be the one to let her know what was happening.
Supt Lim said he agreed and when Khoo's wife turned up, Khoo spoke to his son in a video call, telling the boy to study hard and behave himself.
After his wife left, Khoo said he would take the police to Lim Chu Kang, uttering the words "finish" and "nothing left".
Defence counsel Mervyn Cheong put it to Supt Lim that his client did not use those words, but the police officer disagreed.
Khoo will take the stand when the trial resumes on Tuesday (March 19).
