Suspected serial killer Billy Chemirmir killed in Texas prison

A man who was convicted of two murders and suspected of slaughtering at least two dozen others was found dead in his Texas state prison cell early Tuesday, according to officials with the Texas Department of Criminal Justice.

Billy Chemirmir’s cellmate was identified as the assailant in the attack that led to his death, officials with the TDCJ said.

The 50-year-old had been serving two life sentences without parole in the Coffield Unit in Tennessee Colony near Palestine.

In October 2022, Chemirmir was found guilty of capital murder in the death of 87-year-old Mary Brooks. His first case for another murder ended in a mistrial.
