One resident has not been accounted for after a three-alarm fire at an Everett apartment building.

Other residents told the fire department they have not seen the man who lived in the apartment where the fire apparently started.

The damaged building has to be assessed Friday before investigators can enter to search for the man and try to determine the cause of the fire.

Flames broke out about 9:30 p.m. Thursday in the two-story, 13-unit building near Comcast Arena.

Arriving firefighters were forced back. The fire went to three alarms and burned into the early morning hours.

Two people watching the fire downwind were taken to a hospital with possible smoke inhalation.
