A serial killer accused in the deaths of 22 elderly white women died early Tuesday in the Texas prison where he was serving life without the possibility of parole.
Billy Chemirmir, 50, was found dead in his cell at Coffield Unit in Tennessee Colony, Texas Department of Criminal Justice spokeswoman Hannah Haney said.
She said his cellmate – who is also serving a life sentence for murder – was identified as the assailant, but she could not release his name or how Chemirmir died.
The Office of the Inspector General is investigating his prison death — which came after prosecutors in two Texas counties decided not to seek the death penalty for him.
Chemirmir was a healthcare worker who smothered his helpless victims inside their homes or at senior independent living centers to steal their jewelry to sell.
