Mieczysław Zub

While in prison, Zub was aggressive towards his surroundings, forcing the prison authorities to put him in specially-designed shackles and keep him in solitary confinement at the Montelupich Prison in Kraków. On September 29, 1985, Zub committed suicide, a month after a previous unsuccessful attempt to kill himself.

He returned to crime in September 1980 when he raped a young woman. A year later, he committed the first murder. On 19 November 1981, in Ruda Śląska, he raped and strangled a 19-year-old girl in her eighth month of pregnancy. Until the end of 1982, he murdered three more women. In March 1983, when he raped another victim he lost his pass, entitling him to enter the steelworks where he found a job. On March 8, 1983, Zub was detained and during the interrogation he confessed to all crimes.

Mieczysław Zub committed 4 murders and 13 rapes at the turn of the 1970s and 1980s. At the beginning of his criminal activity, Zub was a policeman by profession; he would wear his uniform while committing his crimes, which made him feel unpunished. He made his first robbery on 29 November 1977 in Świętochłowice. He dragged a 14-year-old into the forest on the pretext of explaining a misunderstanding. There he turned her over, laid down next to her and covered her mouth with his hand. Threatening her with a gun, he ordered the girl to undress. The police opened an investigation into the matter, but it did not lead to anything.

In the 1970s, he made several more attacks on women while disguised as a policeman, but he was soon dismissed for disciplinary offenses (which indicated doubts from his superiors towards Zub). After he was released, Zub did not commit any other crime for two years.

Mieczysław Zub (10 October 1953 – 29 September 1985) was a Polish serial killer who killed 4 women in Silesian Voivodeship. The militia gave him the pseudonym Fantomas.
