Billy Kipkorir Chemirmir was born on December 8, 1972, in Eldama Ravine, Kenya. He emigrated to the United States in 2003, gaining permanent residency and working as a caregiver in North Texas.
Quiet and helpful in Kenya, he soon cut ties with family, working also briefly as a car salesman. His criminal actions began when he used caregiving access to enter elderly victims’ homes.
He impersonated medical or maintenance staff, smothered the vulnerable women—often with a pillow—and stole their jewelry.
Victims and Patterns
From May 2016 to March 2018, Chemirmir was linked to at least two dozen elder deaths—22 formal indictments, 2 convictions, 20+ suspected victims.
The attacks spanned Dallas, Plano, Frisco, Richardson—places trusted by seniors. Pillows bore lipstick blood stains; jewelry vanished; most deaths were misclassified as natural.

Investigation and Arrest

Trials and Convictions
Multiple capital murder indictments followed. The first trial (for Lu Thi Harris) ended in a mistrial in November 2021 due to a hung jury.
Retrial began in April 2022; Chemirmir was convicted of Harris’s murder and sentenced to life without parole. In October 2022, he was convicted of murdering 87-year-old Mary Brooks, again sentenced to life.
Prosecutors in both Dallas and Collin counties opted not to seek the death penalty. Remaining charges were later dropped, which many victims’ families found deeply frustrating.
Death
Chemirmir was killed by his cellmate on September 19, 2023, at the Coffield Unit in Tennessee Colony, Texas. The assault, reportedly by stabbing with an edged weapon, caused fatal injuries.
