In the days since his death, Malaysian police arrested three people on suspicion they were involved with his murder. And one of them claims she thought it was all part of a TV prank.
According to police, Siti Aisyah said she was paid to prank men by asking them to close their eyes and spray water in their faces. Authorities said the prank occurred a few times but that when Kim was targeted, the sprayer had dangerous materials inside.
It's unclear how the dangerous materials got into the sprayer.
It's also unclear what charges Aisyah faces. The BBC reports the North Korean government wants Kim's body to be turned over immediately.
