Fire investigators have opened a criminal investigation into a blaze that ignited on Halloween night at an apartment building in Everett, Snohomish County, Washington. The fire forced dozens of occupants to evacuate and left a mother and her two‑year‑old daughter stranded on a fourth‑floor balcony, prompting authorities to treat the incident as a possible crime. Fifteen residents were displaced by the incident.

The investigation is ongoing as officials assess the cause of the fire.
