Convicted North Texas killer Billy Chemirmir, who was suspected in over 20 murders, was killed in a state prison Tuesday morning, officials confirmed to WFAA.

Chemirmir, 50, was serving life in prison without parole after he was twice found guilty of capital murder by Dallas County juries. He was accused of killing 20 other women in Dallas and Collin counties and still faced charges in those cases.

The Dallas County District Attorney's office confirmed they were notified by Texas prison officials that Chemirmir was killed Tuesday morning. State prison officials confirmed that Chemirmir was found dead in his cell early Tuesday and his cellmate, who was serving on a murder charge out of Harris County, was "identified as the assailant."

Dallas County District Attorney John Creuzot told WFAA that Chemirmir was killed after apparently making inappropriate comments sexual in nature towards his cellmate's children. According to Creuzot, the cellmate allegedly beat Chemirmir, dragged him out of his cell and killed him while other inmates watched. No one intervened and Chemirmir may have been stabbed with a pen, Creuzot said.

"Even though they are on lockdown, apparently [the cellmate] somehow opened the door and dragged [Chemirmir] into the hallway and there were other prisoners who saw it and not one intervened and no one called for help," Creuzot told WFAA. "He was basically there for 15 to 20 minutes before anybody with authority could figure out what happened. When they got there, they tried to revive him, but he died."
