A woman died early Sunday in a fire at a house in Seattle’s Mount Baker neighborhood. Her housemate was found safe at a coastal retreat, according to the Seattle Fire Department.

Firefighters originally had been uncertain about how many people were in the home, Fire Department spokesman Kyle Moore said.

Moore said that when firefighters arrived at the 1 a.m. blaze in the 3700 block of Cascadia Avenue South, the first floor of the home was “fully involved with fire shooting out the front and the back.”

Neighbors told firefighters that two women lived in separate bedrooms on the second floor of the two-story house. Firefighters searched the daylight basement but were unable to enter the first floor.

They searched the four second-story bedrooms and found the body of one woman, Moore said.

He said that although there was not much fire on the second floor, the temperature was recorded to be 1,200 degrees Fahrenheit.

“There was a lot of heat,” he said.

Firefighters retrieved the woman but she could not be saved, Moore said.

Authorities were able to confirm that the second housemate was out of town, he said.

The victim’s identity will be released later by the King County Medical Examiner’s Office, Moore said. He did not know the age of either housemate or their relationship.

Moore said the fire was not easily subdued even with firefighters dousing it with 1,300 gallons per minute from a ladder pipe. The cause of the fire has not yet been determined, he said, but damage was estimated at $2 million.

Moore said the “beautiful house” was reported by neighbors to be the first in the neighborhood.

“They said this had once been an apple orchard and this was the original house.”
