It looks like it is a strong possibility that Kim Jong-nam was meeting with a US intelligence agent a few days before he was assassinated by North Korean agents:
A police witness said Monday that the estranged half-brother of North Korea’s leader met with an unidentified Korean-American man on a Malaysian resort island four days before he was murdered, as the trial of two women accused of killing him resumed.
Indonesia’s Siti Aisyah, 25, and Vietnam’s Doan Thi Huong, 29, are accused of smearing VX nerve agent on Kim Jong Nam’s face in a crowded airport terminal in Kuala Lumpur last Feb. 13. They pleaded not guilty to murder charges when their trial began Oct. 2. The two are the only suspects in custody, though prosecutors have said four North Koreans who fled the country were also involved.
Chief police investigating officer Wan Azirul Nizam Che Wan Aziz told the court Monday that Kim flew from Macau to Kuala Lumpur last Feb. 6 and went to the northern island of Langkawi two days later. He said Kim met with the Korean-American at a Langkawi hotel the next day, but he didn’t know the man’s identity and it wasn’t related to the $138,000 in cash found in Kim’s backpack when he was murdered.
Wah Azirul was responding to questions from Gooi Soon Seng, Aisyah’s lawyer, who asked him to confirm a report by the Japanese newspaper Asahi Shimbun that Kim had met in Langkawi with a US intelligence agent who was based in Bangkok.
“Until now, the identity of the man is not known,” Wan Azirul told the court. He said he could not remember the hotel name or whether the room was registered under Kim or the man, prompting a lashing from Gooi for his “severe lapse of memory.” [NY Post]
