Austrian serial killer Elfriede Blauensteiner who is also known as Black Widow murdered her victims so that she can inherit their possessions. She was born on January 22, 1931, in Vienna, Austria and died at the age of 72 from a brain tumor on November 18, 2003.
She was an obsessive gambler who obtained her gambling money by killing 3 - 5 people including her husband by poisoning them with Euglucon between 1981 - 1995. Euglucon lowers the blood sugar level in people and kills people when combined with antidepressive.
She confessed to her first victim in 1981 who was the janitor of her apartment building was abusive towards his wife and children so she "helped commit suicide" by taking his life. Her second victim was her second husband, Rudolf Blauensteiner, in August 1992 who died ten days after being in a strange coma.
Elfriede confessed on January 11, 1996, at the age of 64 to killing five people but later recanted her confession. Elfriede was sentenced to life imprisonment after being found guilty on March 7, 1997, for murdering Alois Pichler who was 77-year-old. Elfriede"s former lawyer Harald Schmidt was sentenced to seven years in prison for being an accomplice to bodily harm and for falsifying the will of Alois Pichler.
It is not proven but is believed that Elfriede dated wealthy senior men, poisoned them, fabricated wills with her victim"s name and then gambled the money away. She was convicted in 2001, just four years later of murdering her husband Friedrick Doecker who was 64-year-old and her 84-year-old neighbor Franziska Koeberl.
Elfriede was convicted of three murders, but Austrian police are convinced that she could have killed at least ten people, but there is no evidence. Elfriede Blauensteiner served less than seven years of her sentence before dying from a brain tumor in a Vienna Hospital on November 18, 2003.
