Suspected North Texas serial killer charged in smothering deaths of 12 elderly women

Billy Chemirmir, 46, has now been indicted on 11 new charges of capital murder in the deaths of elderly women in Dallas and Collin counties.

DALLAS — Updated at 4:22 p.m. Thursday to include new Collin County indictments.

A 46-year-old home health worker is now linked to the deaths of 12 elderly women in Dallas, Frisco and Plano. 

Billy Chemirmir, 46, has been in custody since March 2018 on a capital murder charge in connection with the smothering death of 81-year-old Lu Thi Harris. 

Now he faces new charges in the deaths of 11 other women. Court records show each woman was killed in the same way — smothered by a pillow.

Investigators said early on they believed Chemirmir was linked to more deaths, but he had not faced new charges in a year. 

Five new indictments in Collin County were made public Thursday. Six new indictments in Dallas County were made public Wednesday. 

Chemirmir was indicted this week on six new charges of capital murder in the deaths of elderly women in Dallas County. He was also indicted in Collin County on five new charges of capital murder. 

His bail is now set at more than $9 million. There's also an immigration hold on him, according to Dallas County jail records. 

Court records show Chemirmir is a citizen of Kenya. 

Chemirmir was indicted this week in Dallas and Collin county in the deaths of:

  • Phyllis Payne, 91, on May 14, 2016
  • Phoebe Perry, 94, on June 5, 2016
  • Norma French, 85, on Oct. 8, 2016
  • Doris Gleason, 92, on Oct. 29, 2016
  • Minnie Campbell, 83, on Oct. 31, 2017
  • Carolyn MacPhee, 81, on Dec. 31, 2017

On May 11, authorities exhumed the body of one of Chemirmir's suspected victims from a mausoleum at Restland cemetery.

The Dallas County and Collin County medical examiners have been re-examining hundreds of cases.

The Dallas County medical examiner has reversed its initial findings in six cases. The deaths of those elderly women have now been ruled homicides instead of natural. 

The Collin County medical examiner now has five cases believed to be homicides.

After Chemirmir was arrested in Harris' death last year, investigators found a trove of women's jewelry, cell phones and medical scrubs in his apartment, search records show. 

Authorities started checking hundreds of case files to see if the deaths of elderly women previously believed to be natural could be connected to Chemirmir after he was arrested in March 2018. 

Chemirmir is also charged with two counts of attempted capital murder out of Collin County in connection with the attacks on two elderly women.
