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 1921.²
