Cause of fatal Dartmouth fire released

The cause of a fire that claimed the life of a woman and displaced more than 100 people in Dartmouth last month has been released. 

Officials tell CTV Atlantic the fire was likely caused by the "careless use of smoking materials." 

Halifax Regional Fire and Emergency says it has closed its investigation. 

City spokesperson Brendan Elliott tells CTV Atlantic in a news release that the term "likely" is used by investigators to describe the source in this case as the official cause is undetermined. 

Investigators say the fire started near a couch in the living room of a third floor unit, adding that any evidence that could confirm an official cause was destroyed in the flames. 

Fire crews responded to the blaze at the 80-unit apartment building on Primrose Street on May 19th.
