In a December 2017 article, Kuciak described suspicious activity in a legal case in which Kočner's firm IIDH was suing pharmaceutical distribution company Unipharma and its subsidiary for €45 million. In response, the Ministry of Justice launched an investigation into the actions of the judge involved in the case. In the last article published before his death, Kuciak wrote about suspicious transactions involving Kočner in the Bratislava apartment building Five Star Residence. According to the article, 19 apartments were sold to and from five different firms fully or partially controlled by Kočner at least twice, raising questions about possible tax-related criminal activity.
