Tens of thousands of people rallied in Bratislava and other parts of Slovakia to mark the one-year anniversary of the slayings of investigative reporter Jan Kuciak and his fiancee.
Crowds gathered on February 21 in rallies organized by a group of students and organizations calling themselves For A Decent Slovakia.
The group released a statement saying they demanded a proper investigation of the murders and a trustworthy government.
"If we want to move forward, we have to know the names of those who ordered this monstrous murder," organizers said.
Kuciak was shot dead along with Martina Kusnirova at their home near Bratislava in February 2018. Both were 27 years old.
The authorities have said they believed it was a contract killing linked to Kuciak's work.
The journalist was investigating political corruption at the time of the slayings, which triggered the biggest street protests in Slovakia since the fall of communism in 1989 and a political crisis that led to the fall of former Prime Minister Robert Fico's government in March.
Kuciak was investigating possible government corruption and ties between politicians and Italian mobsters.
Four suspects have been charged, but the mastermind is believed to be still at large.
The U.S.-based Committee to Project Journalists and the International Press Institute on February 19 called on Slovak authorities to "expedite charges against all parties allegedly involved in the murder" of the investigative journalist.
