Leopoldine Kasparek

Leopoldine Kasparek (1893–1921), also known as The Strangler of Vienna, was an Austrian serial killer, arsonist, and thief who attacked 14 wealthy, elderly women in Vienna, Austria, killing four. After gaining enough trust to be let into their homes, Kasparek strangled her victims until they were dead or unconscious before ransacking their homes. Initially sentenced to death for her crimes, her sentence was later commuted to life imprisonment. She remained imprisoned until her death in 1921.

Murders Between 1915 and 1916, Kasparek committed a series of assaults and murders on wealthy elderly women. Ten of her victims recovered from their injuries, three died immediately, and one died from her wounds in the hospital. After Krasparek's victims allowed her into their homes, she strangled them until they were either dead or unconscious. She then ransacked every room in their homes, stealing anything of value.

Kasparek murdered her first victim in 1915. Her second victim was 56-year-old Marie Wurisch, a partially blind woman. After strangling Wurisch unconscious, Kasparek coated her in paraffin wax – a flammable substance – and lit her on fire. When her charred body was discovered, it was initially believed that her death had been accidental. However, investigators reclassified it as a homicide after noticing ligature marks around her neck. On 21 August 1916, Kasparek strangled 80-year-old Zäilie Höstschul to death. On 10 September 1916, she fatally strangled her final victim, 72-year-old Stefanie von Mack.

Between the murders, Kasparek was arrested several times for thefts, robberies, and acts of extortion. She received short prison sentences for these crimes. Her sentence was later commuted to life imprisonment.
