A key witness in the trial of those accused of ordering the murder of journalist Ján Kuciak has testified to a direct link between businessman Marian Kočner and the surveillance of the journalist. Peter Tóth, who collaborated with Kočner at the time of the murder, detailed how Kočner allegedly instructed a surveillance team to focus on Kuciak. The testimony suggests a deliberate targeting of Kuciak prior to his death. Significantly, Tóth indicated the surveillance operation was concluded on the day of the murder. This detail is expected to be central to the ongoing trial, which focuses on establishing the involvement of those who allegedly commissioned the killing. The trial hinges on such specific evidence as prosecutors attempt to build their case against the accused.
