Marián Kočner

Marian Kočner (born 17 May 1963) is a Slovak businessman and convicted criminal. With business dealings mostly in the spheres of risk investment, financial development and property, his name appeared in leaked police documents known as the "mafia lists" in 2005, of a list of people suspected of involvement in organized crime and their vehicles, for use of police patrols. Since 10 December 2019 he has been included in the global Magnitsky sanctions list.

On 27 February 2020, Kočner was sentenced to 19 years in prison for forging $75 million worth of promissory notes to siphon money from Markíza. He was acquitted by a first-degree court in a separate high-profile case related to the murder of investigative journalist Jan Kuciak and his fiancée Martina Kusnirova, a crime which triggered a significant political crisis in Slovakia.
