Park Sang-hak, who says he defected in 1993 after picking up a leaflet sent from South Korea, told CNN he wants to show ordinary North Koreans the true nature of the country’s leader.

Kim Jong Nam was the eldest half-brother of North Korean leader Kim Jong Un.

South Korean intelligence officials say the North Korean leader directly ordered the killing, a claim Pyongyang vehemently denies.

“Even South Koreans were shocked to hear the news of Kim Jong Nam’s assassination,” Park said. “Can you imagine how North Koreans will react?” News of the killing has l ikely gone unreported in North Korea , where the press is tightly controlled by the government. Park hopes the leaflets, SD cards and USB drives will offer people inside North Korea a glimpse of the outside world, including Kim Jong Nam’s death. The killing has sparked a diplomatic row that’s left citizens from both countries trapped in Malaysia and North Korea, respectively. Park has previously used balloons to send pamphlets and other pieces of information to North Korea. Pyongyang considers it a hostile act and tells its citizens the leaflets are South Korean propaganda, defectors say. The North Korean government has tried to kill Park before, likely in part due to his campaign to get information inside North Korea.
