Police plan to conduct an autopsy on a Yangpyeong County official who died after being questioned by the special counsel team investigating former first lady Kim Keon-hee regarding allegations of preferential treatment in a development project.

The Gyeonggi Nambu Provincial Police said Saturday that the autopsy is scheduled for Monday, with a police official saying it is needed to determine the exact cause of death.

The Yangpyeong official, in his 50s, was found dead at his home in the county on Friday morning, along with a note.

The special team interrogated the official as a suspect on October 2 over allegations that a company owned by the family of Kim’s mother, Choi Eun-soon, received preferential treatment in the apartment construction project in Yangpyeong’s Gongheung area between 2011 and 2016.

The official was in charge of matters related to development fees for the county in 2016.

The special team denied either coercing or coaxing the official during the interrogation and said he was granted a lunch break, a dinner break and three additional breaks.
