Stanisław Modzelewski (15 March 1929 – 13 November 1969) was a Polish serial killer known as The Vampire of Gałkówek, active in Łódź, Poland during the 1950s. He completed three classes of primary school and worked in Warsaw as a driver. During 1952-1956 and in 1967, he murdered seven women and attempted to murder six others. Although he is believed to have murdered an eighth victim (which he confessed to), it was never proven as the body was never found. He was sentenced to death and the execution by hanging was carried out in November 1969, in Warsaw.
Modzelewski murdered women between the ages of 18 and 87 by strangling them with a scarf or with his bare hands. He took valuables as well as useless objects from his victims which he then threw away. He executed them with utmost cruelty. The murders also had a sexual motive. The lower part of the victims' bodies were nude and the arrangement of the corpse suggested a penetration of genital organs. Modzelewski was a sadist but it was not verified whether he tortured the victims before or after the murder.

The investigation of the Vampire of Gałkówek's murders was discontinued in 1957. Despite the thoroughness of the investigation, the perpetrator was not found as the police were led astray from the beginning. They assumed that the murderer was a Polish State Railways employee as the crimes were committed near the railway track and some of the women who managed to survive stated that the offender was wearing a uniform. As a result, the perpetrator was not found and the local people continued to live in fear.
10 years later the case was reopened because of the murder in Warsaw. The suspect in the killing of Maria Gałecka was soon found. It was Stanisław Modzelewski, her ex-neighbor and he was known to have had a number of disputes with the victim.
