Yesterday, on Day Two of the trial, Abdul Razak's private investigator, Mr Balasubramaniam Perumal, recalled vividly Ms Altantuya's last days.
Mr Balasubramaniam, 47, the first witness for the prosecution, told the court that two days before she died, Ms Altantuya had introduced herself to him as "Aminah" and told him to convey her demands to Abdul Razak, whom she called a "bastard" at one point after he refused to see her at his house.
The private investigator said he first saw Ms Altantuya and two other Mongolian women on Oct 16 last year, when they stood outside Abdul Razak's house.
Mr Balasubramaniam said she would wait for her former lover outside his
office building in downtown Kuala Lumpur nearly every day.

She even got her own private detective, one Ang Chong Beng, to find out where Abdul Razak lived.
She then took to staking out at his house in the upscale Damansara Heights in the last days of her life, he said.
On Oct 17 last year, Ms Altantuya turned up at Abdul Razak's house again.
She was making a scene outside but Abdul Razak did not go out to see her, and the private investigator called the police, who took her away to the Brickfields Police Station nearby.
Mr Balasubramaniam went to the station on his own and saw an incensed Ms Altantuya was trying to lodge a report against Abdul Razak.
But Mr Ang, who was there with her, advised her against it and, instead, wanted to negotiate a settlement with Abdul Razak.
It was then that Ms Altantuya demanded US$500,000 and three air tickets to Mongolia, presumably for her and the two women with her.
When Mr Balasubramaniam told Abdul Razak about her demands, Abdul Razak said he would discuss the matter with his friend, a senior police officer, who had later introduced him to Azilah, the co-accused.
The following day, Oct 19, Ms Altantuya turned up at Abdul Razak's house a little past 7pm in a taxi.
The political analyst was out to dinner, but Mr Balasubramaniam was at the house, and she waved and left in the cab. He said she returned again half an hour later, and this time got out of the cab.

By then, he recalled, he had told Abdul Razak about the visit. "He asked me to hold a conversation with Altantuya as the police were coming to arrest her," he said.
Mr Balasubramaniam recalled that he had done as Abdul Razak asked and chatted with Ms Altantuya. The woman told him that her father was dead, her mother was in hospital with cancer and her brother had gambled away their apartment in Mongolia, so she had gone to Malaysia to get money from Abdul Razak.
The private investigator said Ms Altantuya also told him that she could not pay for her stay at the Hotel Malaya in downtown Kuala Lumpur.
As they chatted, he added that two men whom he assumed were policemen drove up in a Proton car. The driver of the car told Mr Balasubramaniam that he was going to take Ms Altantuya with him.
He said another man and a woman were also in the car.
When Mr Balasubramaniam met Abdul Razak the next day, Oct 20, for payment, he asked him about Ms Altantuya. He said Abdul Razak claimed he did not know where she had been taken.
