A Kenyan-born man accused of serial murders in the United States is now facing three fresh capital murder charges. 

Billy Chemirmir, 48, was indicted on three more charges of capital murder this week after a Dallas County grand jury returned the indictments. 

According to a report on Dallas Morning News, Chemirmir now faces capital murder charges for the deaths of Margaret White aged 86, Joyce Abramowitz aged 82 and Doris Wasserman aged 90. 

Chemirmir was born and bred in Kabunyony village in Eldama Ravine, Baringo County before he moved to the US in the 1990s after his elder sister reportedly secured visa for him to relocate.  

Abramowitz died in July 2016 and White and Wasserman in August 2016 and December 2017 respectively and all the three died at The Tradition-Prestonwood, a senior living complex in Dallas. 

The three murder cases bring to 17 the total number of capital murder charges being preferred against Chemirmir alongside civil lawsuits that accuse him of killing eight more elderly women. 

The healthcare worker is accused of suffocating his elderly women victims who lived in senior living facilities before making away with their jewelry and other belonging to sale at pawn shops. 

Chemirmir is also alleged to have posed as a maintenance worker or healthcare provider to be able to access the apartments of elderly women in Dallas and Collin counties to commit the acts. 

Police had initially listed most of the deaths in the case as due to natural causes but they are now being investigated on suspicion of foul play. 

Chemirmir was arrested by police in 2018 with police set to review hundreds of other death cases that had been listed as due to natural caused before preferring additional charges. 

A woman who resides at Preston Place in Plano, who survived an attack by Chemirmir in March 2018 filed a report with police and identified him as a suspect leading to his arrest. 

The Kenyan-born suspected serial killer was charged separately in March and June 2016 with criminal trespassing and false identification at a Dallas retirement community and is in prison after he failed to raise $11.6 million (Sh1.18 billion) in bail. 

Chemirmir faces the death penalty if convicted for the multiple murders. 

In Texas, capital murder carries either automatic life imprisonment without parole or the death penalty. Prosecutors reserve the death penalty for offenses deemed heinous.
