Krzysztof Gawlik
Krzysztof Gawlik got his nickname from murdering people with the Škorpion type silenced machine gun. Each victim was shot several times with a characteristic execution shot in the back of the head, along with some stabbing traces on the body. Gawlik's first victim was an almost 18-year-old prostitute Sylwia L. from Poznań. The murderer met her (apparently) on February 6, 2001, responding to an advertisement she placed in the press. The next victim of "Scorpio" was an Ukrainian - Lesia H., a prostitute working in Wrocław and Tomasz S., a man associated with her. He shot them three days after committing the first crime, according to various sources in a public house of their apartament in Wrocław. In March 2001, Gawlik killed another two people - a married couple from Wrocław, whom he most likely from responding to their car sales offer.
