diabetes drugs, sedatives and even industrial alcohol in order to inherit their property. Akbari's sick actions went undetected for more than two decades, due to her victims old ages and health conditions, until she confessed to the killings. She currently awaits sentencing. The families of her victims are now asking for her execution.  Beginning in 2000 and carrying on until 2023, she killed over and over until she became careless with her final husband,  82-year-old Gholamreza Babaei.

Babei's son was suspicious of the woman after a family friend revealed his own father had previously been married to a woman called Kolsum who had tried to poison him.  Police were called, and the woman was arrested. Upon interrogation police managed to get her to confess, though she reportedly gave conflicting accounts on just how many people she killed. She said: 'I don’t know how many I killed. Maybe it was 13 or 15 people. I don’t remember exactly.' (Dailymail)
