Public prosecutor Wan Shaharuddin Wan Ladin said as many as 10 samples will be exhibited in the Shah Alam courtroom today, which marks the third day of the trial.
She said Kim told her "he was attacked from behind by two women", with one of them wiping something over his eyes. There has been no testimony about the motive for the killing, but North Korean leader Kim Jong Un is believed to have considered his older sibling a potential rival for power.
Monday's court session was primarily a reconstruction of Kim Jong Nam's final moments at the airport.
Siti Aisyah of Indonesia and Doan Thi Huong of Vietnam pleaded not guilty to murder as their trial opened Monday.
A copy of the post-mortem report, submitted as evidence, showed that traces of VX were found not only on Kim's eyes and face but also in his blood and urine, and on his clothing and bag. They included a type of Viagra typically used by heart patients, but he said those drugs and those conditions would not have caused Kim's swift death.More news: Two killed in Pakistan shelling on LoC (Second Lead)
Prosecutors also sought Wednesday to show VX was the sole cause of death.
However, he concurred with Gooi on the possibility that the VX poison was injected into Kim Chol, but it was hard to detect the injection as the victim's body was full of tattoos.
The hearing continues Thursday before Justice Azmi Ariffin.
Under cross-examination by defense lawyers, Mohamad Shah acknowledged he had limited knowledge of VX and nerve agents in general.
Government pathologist Mohamad Shah Mahmood, who prepared the report, told the court Tuesday that "the cause of death is acute VX nerve agent poisoning" after excluding other possible diseases or injuries. "There is a very slim chance of survival" if VX has entered the bloodstream, he said.More news: Senate Intel Heads Say Trump-Russia Collusion Still an Open Question
He said the report is based on interviews with people who will be called to testify as witnesses, therefore the information is not hearsay or prejudicial.
Dr Nur Ashikin Othman agreed with defence lawyers that the normal readings could indicate that the two suspects were never in contact with any VX nerve agent, but she said it could also mean they were exposed to only low amount or that it was washed off quickly.
This came after defence counsel Datuk Naran Singh, who acted on behalf of accused Vietnamese Doan Thi Huong, asked whether he (Dr Shah) agreed that the deceased's identity as Kim Chol was confirmed after a DNA comparison with samples taken from Kim Chol's son.
On Tuesday, doctors who treated Kim told the court he arrived at the airport clinic in pain with very high blood pressure and pulse.
He said the first time he saw Kim Chol's body was at the Putrajaya Hospital on Feb 14 while the post-mortem was conducted at 12.45pm the following day because of a protest from the Korean embassy.More news: Yahoo Triples Likely Scope of '13 Hack to 3 Billion Users
