The deadly fire at an assisted-living facility in Fall River, Massachusetts, was accidental, however, the cause is classified as undetermined because investigators found two possible origins, officials said.

Etzkorn said that the Garbiel House is working on returning possessions to displaced residents and determining a method to prevent a similar tragedy from occurring in the future.

The owner of the Gabriel House in Fall River said in a statement Friday that his focus remains on the families who lost loved ones in a fire at the assisted living facility.
