"She doesn't want her family get sad to see her condition," Erwin said after a 30-minute meeting with Aisyah. "She only delivered a message through us to her father and mother not to be worried and take care of their health."
The public poisoning of Kim Jong Nam, which took place Feb. 13 amid crowds of travelers at the airport, appeared to be a well-planned hit. Kim was dead within hours of the attack, in which two women went up behind him and appeared to smear something onto his face.
Aisyah, 25, has said previously that she was duped into the attack, but Malaysian police say she and the other female suspect, a Vietnamese woman who also is in custody, knew what they were doing.
The revelation that VX nerve agent killed Kim has boosted speculation that North Korea had dispatched a hit squad to Malaysia to kill Kim, whose younger half brother is Kim Jong Un.
The thick, oily poison was almost certainly produced in a sophisticated state weapons laboratory, experts say, and is banned under international treaties. North Korea, a prime suspect in the case, never signed that treaty, and has spent decades developing a complex chemical weapons program.
Though Kim Jong Nam was not an obvious political threat to his sibling, he may have been seen as a potential rival in the country's dynastic dictatorship.
Malaysia hasn't directly accused the North Korean government of being behind the attack, but officials have said four North Korean men provided the two women with poison. The four fled Malaysia shortly after the killing.
On Saturday, police confirmed that a raid earlier in the week on the outskirts of Kuala Lumpur was part of the investigation. Senior police official Abdul Samah Mat, who is handling the investigation, did not specify what authorities found there, but said the items were being tested for traces of any chemicals.
