One person has died after a house fire in Burnaby early Friday morning, officials said. Burnaby RCMP said crews were called to the fire on Douglas Road, near Norfolk Street, just after 4:30 a.m. The Burnaby Fire Department said 36 firefighters responded and found heavy fire and smoke at the multi-unit residential home. They spent several hours confining the flames to the building. Firefighters explained they were told that one occupant was unaccounted for. Crews entered the home to find and rescue them, but they unfortunately succumbed to their injuries despite life-saving efforts, officials said. B.C. Emergency Health Services said three patients were hospitalized as a result of the fire, one in serious condition and two in stable condition. Police said a section of Douglas Road was closed for several hours but has since reopened. Photos from the scene showed the broken windows, charred structure, and the front yard taped off. Burnaby RCMP said its Investigative Support Team is working with arson investigators to determine the cause of the fire.
