The Zagreb office of the State Attorney General on Wednesday filed an indictment against a 57-year-old Austrian citizen, Harald Kopitz, for the murder of his three underage children last September.

Kopitz is charged with first-degree murder.

Kopitz killed his three underage children in a flat in Zagreb’s Mlinovi neighbourhood and then attempted suicide. At the time of the crime, the children’s mother was out of town and they were spending the weekend with him.

The prosecutors are demanding an extension of Kopitz’s pretrial detention due to the gravity of the crime he committed and the risk of repeating this crime.
