Billy Chemirmir, 46, is accused of going on a killing spree across Texas, taking the lives of senior citizens before stealing from their homes.
Plano Police Chief Gregory Rushin told reporters last year that the Kenyan national used his “health care experience to his advantage, targeting and exploiting seniors," calling it "terribly disturbing."
Now Dallas County prosecutors are seeking the death penalty against Chemirmir.
The latter is reserved for crimes considered especially heinous, according to the Morning News.
A trial date has not been set in the case as of yet and Chemirmir remains in jail on $11.6 million bail. Immigration and Customs Enforcement has placed an immigration hold on him since he is in the United States illegally.
The filing for the death penalty was specifically in the case of Lu Thi Harris.
Harris, 81, was found dead by officers conducting a welfare check.
During the arrest, officers found Chemirmir with jewelry and money and in the dumpster officers found a jewelry box containing jewelry and a name. Officers connected the box to a house in Dallas and went inside to find Harris dead from homicidal violence.
Chemirmir was arrested and charged with capital murder.
Police had been surveilling Chemirmir because they suspected he was involved in the attempted murder of a 91-year-old woman. Rushin told reporters last year that he told that victim "go to bed and don't fight me."
“She complied and the suspect put a pillow over her face, causing her to lose consciousness, and he then stole her jewelry," he said.
Authorities found a third woman, 93, who said she was assaulted by Chemirmir.
“He knocked a 93-year-old woman to the floor from her walker and smothered her with a pillow,” Rushin said. “Who does that?”
The three incidents triggered a widespread probe of past deaths that the Kenyan national may have committed, revealing over a dozen others authorities believe he carried out.
Latest Lawsuit
A lawsuit filed recently accused Chemirmir of being involved in the death of a 90-year-old woman, the 19th killing or attempted killing Chemirmir has been linked to.According to the suit, 90-year-old Doris Wasserman played with her great-grandson on Dec. 23, 2017. Her family left around 3:30 p.m. and came back at around 8 p.m. to find her unresponsive on her bed.
Despite signs indicating strangulation or suffocation, Dallas police officers "found no evidence of foul play."
Police told the family later that tracking data from Chemirmir's phone placed him in the area of Wasserman's apartment at the The Tradition-Prestonwood home between 3:05 p.m. and 4:31 p.m.
Quentin Brogdon, an attorney representing the woman's family, said that Chemirmir will probably be charged in the death.
"The timeline and the circumstances surrounding Doris Wasserman's death leave no doubt whatsoever that Doris Wasserman was yet another preventable, unfortunate victim of Billy Chemirmir," Brogdon said in an email to the Morning News. "This lawsuit is being filed to hold The Tradition legally accountable for the foreseeable criminal acts of Chemirmir, a vicious predator who was emboldened, enabled, and empowered by The Tradition."
