Fire officials in Langley will be picking through the charred  remains of a fourplex today, looking for the cause of a deadly  blaze.

Langley firefighters confirmed one person is dead and two others are in hospital -- one in critical condition -- after fire swept through the older, wooden structure in the 23800-block of Old Yale Road.

The blaze broke out at around 6:45 p.m. and when they arrived, crews found one section of the fourplex already engulfed. There's concern that the building may not have been equipped with  working smoke alarms.

One person was killed at the scene and another was airlifted to hospital with life-threatening injuries. The third victim was taken to hospital via ambulance with what are believed to be less serious wounds.

Few details have been confirmed but the building owner told CTV News the deceased was an elderly woman who lived there for more than a decade.

The Langley Township Fire Department has yet to identify the cause of the fire.

Streets around the scene were closed through the night and  RCMP Cpl. Holly Marks says it will be later this afternoon before she expects any update on the cause of the fire or the  identities of the victims.
