Shah Alam (Malaysia): A Vietnamese woman accused of killing the North Korean leader’s estranged half brother told police she realised she had been used to murder him after she was detained, her lawyer said Tuesday.

Doan Thi Huong and co-defendant Siti Aisyah from Indonesia were charged with murder after Kim Jong Nam died at Kuala Lumpur’s airport on Feb. 13 last year. The two are the only suspects in custody, though prosecutors have said four North Koreans who fled the country were also involved.

The court heard earlier that Huong told police after she was detained last year that she was recruited by a Korean man known as Mr Y in a Hanoi bar in December 2016. Mr Y has been identified in court as Ri Ji Hyon, one of the four North Korean suspects who fled Malaysia.

On Tuesday, the court heard that Huong thought she was playing a harmless prank for a hidden camera show and only knew Kim was dead after police told her. Her lawyer Hisyam Teh Poh Teik said Huong told police that Mr Y put an oily substance on her hands and told her to rub her hands together before smearing it on Kim’s face but that she didn’t know it was the VX nerve agent.

Huong also told police that Mr Y didn’t ask her to wash her hands or to keep her hands away from her body but that she did so on her own because the substance was oily, smelly and felt uncomfortable, Teh said. She went to a restroom on another floor to wash her hands because Mr Y had told her to leave the scene immediately after the prank.

The court heard that Huong was told by Mr Y that the video on February 13 would be important as it would be uploaded on YouTube. She told police she wasn’t able to contact Mr Y after that. She returned to the airport two days later to carry out another prank but there was no sign of Mr Y and she was detained shortly after.

“He is liar. He used me to do video on 13/02/2017 for him,” she said in her police statement, read out by Teh.

Two days before the attack on Kim, Huong told police she was given Johnson’s baby cream for a similar prank at the airport and didn’t wash it off.

The two women face the death penalty if convicted, but not if they lacked intent to kill. Prosecutors contend the women, who both were seen on security videos holding their hands away from their bodies as they rushed to wash off the oily liquid, knew they were handling poison.

Earlier, Teh told the court that Huong had told police she was an actress as she was paid to act in two video prank shows in Hanoi in 2016, which were uploaded on YouTube. The Vietnamese man who made those videos gave the court sworn statements that he recruited Huong, whom he knew just as “baby,” to act in his videos as he couldn’t come to Malaysia to testify.

Kim, the eldest son in the family that has ruled North Korea since its founding, had been living abroad for years after falling out of favor. It is thought he was assassinated because he was perceived as a threat to the rule of his half brother, Kim Jong Un. Malaysian officials have never officially accused North Korea of involvement in Kim’s death and have made it clear they don’t want the trial politicized.
