Durham police have identified the person killed in a blaze that tore through a historic building in Bowmanville earlier this month as 54-year-old Kelli Faris.

In a social media post Thursday, police said an autopsy found "no signs of foul play" on Faris's remains and investigators believe she died of injuries caused by the fire.

The Office of the Ontario Fire Marshal has finished its examination of the scene and "efforts to determine the cause, origin, and circumstances" of the blaze are ongoing, police added.

The century-old building on King Street W. in downtown Bowmanville was severely damaged by the fire that broke out in the early morning hours of March 6.

Two dozen people were displaced from their homes on the second and third stories of the building, and multiple businesses at street level were forced to temporarily close.

Police first confirmed they had found human remains at the scene on March 10.

Anyone with information that could help investigators is asked to contact Durham police or to leave an anonymous tip with Crime Stoppers.

In a statement Thursday, Ontario Fire Marshal Jon Pegg said that last week was "challenging … with several fatal fires that destroyed multiple families, devastated our communities and indiscriminately took the lives of children and adults alike."

Though the statement did not refer to specific incidents, a mother and her two children died in a house fire in Oshawa last week. In another incident also last week, a child and a woman died after a fire in a trailer park in Trenton.

On Tuesday, a woman died and a man was critically injured after a fire at a highrise residential building in North York.

Pegg said fire investigators are working to determine the "origin, cause and circumstances of these fires."

"It's still unknown if there were working smoke alarms in the homes where any of these fires occurred," his statement says.

Pegg encouraged people to test smoke alarms every month and practice a home fire escape plan that considers the ages and abilities of everyone in the household.

"A prepared household is best positioned to survive a house fire," he said.
