Billy Chemirmir, a Kenyan Charged with Murder of 12 Elderly Women in the US, Linked to Another Death

The family of an elderly Dallas woman who died in December, 2017 has filed a lawsuit against an assisted living facility where she lived.

The family of 90-year-old Doris Wasserman claims that she died in the hands of an accused serial killer, Billy Chemirmir, a Kenyan immigrant who is already facing several murder charges.

The family accuses The Tradition-Prestonwood Assisted Living and Memory Care, where Wasserman died, of failing to provide adequate security for residents. In the lawsuit, the family says their kin did not die of natural causes.

Chemirmir, a healthcare worker, currently faces charges for the murders of 12 elderly women in the Texas counties of Dallas and Collin. 

The 46-year-old is accused of either strangling or suffocating his victims to steal jewelry and other valuables.

Wasserman's family says $8,500 worth of jewelry was determined to be missing from her apartment after her death.

Their lawsuit notes that Police said that Google tracking data placed Chemirmir in The Tradition-Prestonwood between 3:05 pm and 4:31 pm on December 23rd, 2017, the day Warsame died. Wasserman died at around 3:30 pm, according to the lawsuit.

"We believe that The Tradition put profits over the safety of its residents. To say that this family is devastated and feels betrayed by The Tradition would be a gross understatement," the family's attorney Quentin Brogdon said. 

"Doris Wasserman and her family entrusted Ms. Wasserman's safety into the hands of The Tradition because of The Tradition's promises about safety and security -- promises that were made but never kept."

Wasserman is the ninth alleged victim of Chemirmir who lived at The Tradition-Prestonwood. 

Chemirmir is currently in the Dallas County Jail in lieu of a $11.6 million bail.
