Biography
Billy Kipkorir Chemirmir was born in Kabonyony village, a Kenyan suburb of Eldama Ravine. His father was a long-serving village chief.
Chemirmir had convictions for driving under the influence in Addison and Dallas in 2010 and 2011, receiving fines and short custodial sentences. In July 2012, Chemirmir was arrested for assault on a female companion and in June 2016 for trespassing at Edgemere Retirement Community. He pleaded no contest to both charges later that year.
Crimes
Chemirmir was accused of posing as a medical professional or maintenance person and gaining access to the properties of at least twenty-two elderly women and smothering them with a pillow. Police in several North Texas communities have investigated Chemirmir for additional victims, believing that a number of previously reported natural deaths may be linked to him.
Trial
Chemirmir was arrested in March 2018, accused of smothering 81-year-old Lu Thi Harris to death. He was indicted on 11 additional counts of capital murder in May 2019. On February 7, 2020, trial was set for April 5, 2021. The trial was later delayed to November 12, 2021. Chemirmir's trial began November 15, 2021. On November 19, 2021, a judge declared a mistrial due to an 11–1 jury deadlock. Chemirmir's retrial began April 25, 2022.
On April 28, 2022, Chemirmir was convicted in the murder of Harris and was sentenced to life in prison. Dallas County District Attorney John Creuzot told families in May 2021 that his office would not seek a death sentence for Chemirmir.
On August 24, 2023, Collin County District Attorney Greg Willis announced he also would not seek the death penalty for Chemirmir. Chemirmir's trial for the murder of Mary Brooks began on October 3, 2022. On October 7, 2022, Chemirmir was convicted in the murder of Mary Brooks and was sentenced to life in prison. After his convictions, the remaining charges against Chemirmir were dismissed, which disappointed many of his victims' families.
Death
Chemirmir was killed by his cellmate on September 19, 2023, at the Coffield Unit in Tennessee Colony, Anderson County, Texas. He was 50 years old. The alleged attacker was Wyatt Busby, who had been serving a 50-year sentence for the 2016 stabbing death of a Houston area man. Prior to his death, Chemirmir had allegedly made sexual comments about his cellmate's children.
