For years Dana Kontrová was subjected to psychological and physical attacks from her husband. She repeatedly warned the police that he was violent and mentally unstable.
One complaint came after Ms Kontrová’s husband beat her with an electric cable. Two months later, the police were telephoned and warned that he had a shotgun and was threatening to kill himself and the children.
Under Slovak law, the police should have launched a criminal investigation and taken steps to protect the family. However, they did neither of these things.
Two days later the man took a shotgun and murdered the couple’s two children, aged five and one. He then turned the gun on himself.
