The search is over at the site of a fire in L’Isle-Verte, Que., that destroyed a seniors' home, killing at least 27 people.

Five more people are still considered missing.

Bone fragments uncovered in the rubble of the Résidence du Havre seniors’ home on Jan. 23 have been sent to the coroner’s office in hopes that its expertise in forensic testing will provide answers to the families still awaiting news about the fate of their loved ones.

The coroner’s office will use DNA testing to try to identify the other remaining victims.

Police are still investigating the cause of the fire, and officers are now mandated to search for clues that could be admissible if the case goes to court.

A warrant was issued for the collection of clues late on Friday afternoon.

Investigators are considering multiple scenarios, including one in which the fire may have been the result of a criminal act.
