Billy Chemirmir, a Kenyan citizen was on Tuesday found dead in his cell in Texas, United States of America.
Chemirmir was convicted of murder in 2023 after he was found guilty of killing two people and a dozen other elderly women in Dallas, Texas.
According to the Guardian, Chemirmir, 50, was murdered by his cellmate, whom the authorities in the prison are yet to name, and state how he was murdered.
It further reported that Chemirmir was convicted of capital murder once in April 2022 and again in October in two separate cases in Dallas County.
With the cases, Dallas prosecutors dropped additional charges against him and opted not to seek the death penalty.
Born in Eldoret, Uasin Gishu county, Chemirmir had been in police custody since March 2018 over the death of Lu Thi Harris, 81, also from Dallas.
Police found evidence linking him to the Harris murder when he was being investigated in the Dallas suburb of Plano for suspicious death and suspicious person calls.
He lived in the US as a permanent resident, and his killing spree began around 2016.
Just as the authorities were conducting an investigation on one case, they found out Chemirmir had broken into the apartment of a 91-year-old woman, Dallas.
As his case was going on, the police found out that Chemirmir positioned himself as a caregiver, and would go to the homes of older women, to gain access to their expensive jewellery, and in the process would force a pillow over their face, suffocating them to death.
During the trials, it was stated that Chemirmir would sell the jewellery he acquired online.
Chemirmir had also faced family violence charges and was on many occasions arrested for drunk driving. The cases occurred between 2010 and 2011.
Until his death, the 50-year-old had maintained his innocence, and had in 2022, hoped not to be sent to prison.
He had also appealed for conviction.
“I am not a killer, I am not at all what they’re saying I am. I am a very innocent person. I was not brought up that way. I was brought up in a good family. I didn’t have any problems all my life," Chemirmir said.
He said he was brought up in a humble household, where he grew up on their farm while taking care of his father.
