Prosecutors demanded a four-year prison sentence for former National Security Adviser Suh Hoon, who has been accused of covering up the 2020 killing of a South Korean fisheries official.

The prosecution told the Seoul Central District Court on Wednesday, the final day of Suh's trial, that the former official had abused his authority to hide North Korean troops' shooting of a civil servant in the West Sea in 2020 and manipulated reports to depict the victim as a defector, saying he had “deceived the public and disgraced the victim’s family.”

They also asked the court to hand a three-year sentence to former Defense Minister Suh Wook and a two-year suspended term to former National Intelligence Service chief Park Jie-won, arguing the two had colluded to destroy official records.

Prosecutors say Suh ordered military and Coast Guard officials to keep the incident secret and release false statements suggesting that the late official was voluntarily heading north.

They added that he “failed to act as the control tower during a national crisis and instead orchestrated a cover-up.”

The court is expected to deliver its ruling in the coming weeks.
