Kenyan Immigrant, Named North Texas’s Deadliest Serial Killer, Killed in Prison

John Binder, Breitbart, September 19, 2023

Billy Chemirmir, a 50-year-old Kenyan accused of murdering 24 elderly American women and convicted for two of the murders, has reportedly been killed by his cellmate at a prison southeast of Dallas, Texas.

The Dallas County District Attorney’s Office confirmed to WFAA that Chemirmir was found dead in his prison cell on Tuesday morning at the Coffield Unit in Tennessee Colony, which is southeast of Dallas. His cellmate was “identified as the assailant,” according to officials.


Chemirmir stole from his elderly victims, posing as a caregiver, before selling their belongings on eBay from April 2016 to April 2018. To murder his victims, Chemirmir would smother them with a pillow, leading investigators to first assume that many of the victims had died of natural causes.


Soon after Chemirmir’s arrest in May 2019, Breitbart News exclusively reported that Chemirmir, born in Kenya, first arrived in the United States on a B-2 tourist visa in July 2003. Though Chemirmir was supposed to be in the United States only temporarily, he overstayed his visa, this becoming an illegal alien.

In November 2007, though, Chemirmir was able to obtain a green card after marrying an American citizen. Chemirmir had a criminal record, Breitbart News exclusively learned, including convictions for drunk driving, trespassing, assault, and obstructing a police officer.
