One person died during a two-alarm fire in North Renton this weekend. The fire is still under investigation.

According to Renton Fire Department Deputy Chief Erik Wallgren, firefighters were called to a structure fire in the 300 block of Factory Avenue North at about 9 p.m. Friday, Jan. 8.

Firefighters arrived at the two-story residence to find the building fully engulfed and upgraded the fire to a second alarm to protect the exposed buildings on either side.

Wallgren said the fire proved challenging because structural stability of the home had been compromised because of the amount of fire. As firefighters tried to enter, they noted the stairwell from the first to second floor had burned away, making it too risky to enter. Firefighters had to work off a ladder truck platform to put water on the flames from above and through exterior windows.

After the fire was knocked down, firefighters were able to enter the residence and discovered the victim on the second floor.

The fire investigation has been turned over to Renton Police.

On a high note, firefighters were able to rescue a dog from the building, which Wallgren said was a “miracle” in its own right.

The dog, a 4-year-old Yorkshire terrier named Killer, was treated and transported to the BluePearl Veterinary Partners Hospital in Renton, where he is expected to make a full recovery.

According to a press release from the hospital, Killer was weaned off of oxygen by 2 a.m. A friend of the family came forward to claim ownership of the animal, though he stayed at the hospital for 24 hours for observation. BluePearl is treating him ay no charge, though anyone interested in making a donation should contact Frankie’s Friends, an organization that provides financial assistance to pets who need lifesaving care in the Seattle Area.
