Has a serial killer been caught? Police say man accused of smothering mother, 81, may have killed more elderly women

Dallas police say a man in jail for allegedly killing his mother and attempting to kill two other women may have harmed additional victims.

NBC reports Billy Chemirmir, 45, is facing capital murder charges for the death of his 81-year-old mother, Lu Harris. Authorities found her lying lifeless in her Dallas home on Tuesday. Her cause of death was listed as suffocation due to smothering.

Plano officers began conducting surveillance on the suspect earlier this month after numerous elderly women began dying at the same nursing home he worked at as a health care aide.

On March 20, they noticed him throw something into a dumpster off of the 4500 block of Pear Ridge. They confronted Chemirmir and learned he had an outstanding warrant for jewelry theft. After placing him under arrest, officers found a box in the dumpster with the name “Lu Thi Harris” written across it. Officers went to Harris’ home to check on her, and found her dead from foul play.

Police allege that the suspect also tried to smother 91-year-old woman at her apartment in Plano on March 19. According to the police report, Chemirmir forced his way into the elderly woman’s apartment, then said, “Go to bed, don’t fight me,” before stealing her jewelry and trying to smother her. The victim lost consciousness but survived the ordeal.

The suspect was also tied to a case stemming from an incident in Frisco that left a 93-year-old nearly dead. According to authorities, Chemirmir posed as a maintenance man and broke into the woman’s home at Parkview Elderly Assisted Living. The victim said the suspect smothered her, but she pretended to be dead so he would leave. She survived the incident.

Chemirmir is behind bars in Dallas County jail with a $1,000,000 bail amount. Authorities stated there could be additional victims. They’re currently hundreds of cases for similarities.

“We don’t really know how many cases he may be suspect in,” Plano Police Chief Greg Rushin said, according to FOX News.

Anyone with any information is urged to contact authorities at 972-941-5785.
