Leonid Greyser is also known by his alias Grazer Russian Killer.
Known for his unusual appearance of shaved head and whitish skin complexion, he has confessed to having a connection to Satan or Lucifer.
Now notorious for slaying his own sister, Ariada Korol with whom he shared an apartment, Greyser is not a figure of affection.
He has shown no remorse for his past actions and is spending his days behind the bar.
Apart from that, not many details about his personal life can be attained at the moment.
Greyser was just an 18-year-old teenager when he killed his sister following the orders of Satan.
His recently found fame has landed him in international fame and hate comments on him.
