On 21 February 2018, Jan Kuciak, an investigative journalist of the news website Aktuality.sk, was shot dead together with his fiancée, Martina Kušnírová in their home. He focused mainly on investigating tax fraud of several businessmen with connections to top-level Slovak politicians. The murders sparked mass popular protests and a political crisis which culminated on 15 March with the resignation of Prime Minister Fico and his entire cabinet. In September 2018, Slovak police stated that Kuciak was murdered because of his investigative work, and that the murder had been ordered. They arrested eight suspects, charging three of them with first-degree murder. On 14 March 2019, police charged businessman Marian Kočner with ordering the murder of Ján Kuciak and his fiancée Martina Kušnírová.
