UNIAN memo. Ukrainian journalist Georgy Gongadze, who had been exposing high-level political corruption, was kidnapped in September 2000, and his decapitated body was later found outside Kyiv.

Then-President Leonid Kuchma was accused of involvement in the murder based on audio recordings secretly made in his office.

Prosecutors charged Kuchma with involvement in the case in 2011, but a court dropped the charges later the same year.
