The Russian Female Serial Killer - The Irina Gaidamachuk Story

Irina Gaidamachuk was a Russian serial killer who spent nearly a decade preying on elderly women across the Sverdlovsk region, posing as a social-services worker to slip into their apartments before bludgeoning them to death and stealing small amounts of cash to fuel her alcoholism. Her crimes stretched from 2002 to 2010 and baffled investigators, partly because police assumed the killer was a man.
