In a shocking turn of events, convicted murderer and suspected serial killer Billy Chemirmir was found dead in his prison cell on Tuesday morning. The Texas Department of Criminal Justice has confirmed the news, stating that Chemirmir was killed by his cellmate.

Billy Chemirmir, 50 years old, had been convicted of killing two elderly women and was suspected of being responsible for the deaths of nearly two dozen others in Dallas and Collin counties. He had been sentenced to life without parole for his heinous crimes.

Investigation reports suggest that Chemirmir would rob his victims and then smother them to death after gaining access to their homes or senior living facilities by pretending to be a maintenance worker. His reign of terror came to an end when he was apprehended and imprisoned at the Coffield Unit in Anderson County, located approximately 100 miles southeast of Dallas.

Interestingly, it has been revealed that Chemirmir's cellmate, who was also convicted of murder, is the one who killed him. Further details regarding this incident are still not available at the moment.
