Last year four man were charged by investigators in Slovakia related to the murder of investigative journalist Jan Kuciak and his fiancée. But despite the arrests, authorities had refused to identify the person who ordered the killings. On Thursday, however, Slovak prosecutors charged Slovak businessman Marian Kocner. "The reason for the murder was the journalistic work of the victim (Kuciak)," the prosecutor added. "We don't have a weapon, but we have evidence of the weapon and ammunition," he said, while also not ruling out that more individuals could be accused of involvement in the murder.
