BRATISLAVA, Slovakia — Slovaks paid a final farewell Saturday to Jan Kuciak, an investigative journalist who was shot dead with his fiancee, with the archbishop declaring that everyone in the nation now wanted to know about Italian Mafia influence, thanks to Kuciak’s reporting.

A funeral Mass for Kuciak was held at the church of St. Francis of Assisi in the town of Stiavnik in western Slovakia, with his parents, friends and fellow journalists packing the aisles.

The bodies of 27-year-old Kuciak and Martina Kusnirova were found last Sunday in their house in the town of Velka Maca. They had planned to get married in May.

Kuciak was reporting about the influence of the Italian Mafia in Slovakia and its possible ties to people close to Slovak Prime Minister Robert Fico. Two of Fico’s associates resigned last week following the reports.

“If the murderer wanted to silence Jan, he managed quite the opposite,” said Bratislava Archbishop Stanislav Zvolensky. “There’s not a single person who wouldn’t know what happened.”
