Kim Jong Un’s half-brother was working as a CIA informant before he was brazenly murdered in a Malaysian airport in 2017.

A Vietnamese woman tried in the case of Kim’s death was released from a Malaysian prison and returned to her native country earlier this month.

The 30-year-old and her co-defendant, Indonesian Siti Aisyah, were charged with colluding with four North Koreans to murder Kim Jong Nam.

In March, the Malaysian attorney general stunningly dropped the murder charge against Aisyah, following high-level lobbying from Jakarta.
