BRATISLAVA, Slovakia (AP) — Slovakia's prosecutor general says authorities have renewed their investigation into threats by a businessman against an investigative journalist who was shot dead last week with his fiancee.

The bodies of 27-year-old Kuciak and Martina Kusnirova were found Feb. 25 in their house.

Last year, Kuciak alleged that the businessman, Marian Kocner, threatened him following the publication of a story about him. The reporter said he filed a complaint with police and alleged they failed to act.

Prosecutor General Jaromir Ciznar said investigators will return to the threats though he personally didn't believe this case had anything to do with Kuciak's death.

In his last unfinished story, Kuciak reported about the influence of the Italian mafia in Slovakia and its possible ties to people close to Slovak Prime Minister Robert Fico.
