Murderer who preyed on older women killed by cellmate in Texas prison

Billy Chemirmir, 50, was convicted of two murders and accused of killing nearly two dozen women

A man who Texas authorities say smothered at least two dozen elderly women in a two-year killing spree, while stealing possibly millions of dollars worth of jewelry and other valuables, was himself murdered on Tuesday morning by a prison cellmate, according to the state's criminal justice department.

Billy Chemirmir, 50, worked as an in-home caregiver and posed as a maintenance worker to gain access to luxury independent living communities in and around Dallas. He would gain access to the apartments of seniors then force a pillow over their face, smothering them to death before raiding the apartment of its valuables to pawn or sell online.
