A fatal fire tore through a North Flower Street fourplex early Friday morning.

One person was killed, four were injured and 14 people were displaced, according to the Anchorage Fire Department and the Red Cross. A 911 caller first reported seeing flames from a first-floor apartment on the 400 block of North Flower Street at 2:48 a.m., and the first fire trucks arrived on the scene within three minutes, firefighters said. By 3 a.m., dozens of fire engines, ambulances and police cars filled the road, blocking the intersections at Thompson Avenue and Peterkin Avenue while firefighters fought the blaze. Flames shot through the roof of the building; neighbors gathered in the street outside.

One person was trapped in the apartment where the fire began and did not survive, firefighters said. Three others were taken to a local hospital in stable condition and a fourth person was in serious condition, according to AFD. The Red Cross is providing financial assistance for immediate needs and lodging to 14 people displaced by the fire, according to a spokeswoman for the organization.

The fire was brought under control by 3:46 a.m., according to AFD. Hours later, a lone fire investigator remained on scene, surveying the charred building. The cause of the fire remains under investigation.
