Seattle Fire responded to a serious house fire in the 400 block of 16th Ave E Thursday morning just before 9 AM.

One victim was found deceased inside as the fire in the two story house was knocked down and under control by around 9:05 AM. A search for other possible occupants was underway.

A Seattle Fire spokesperson said the victim, a female in her 90s, was found on the first floor of the house and was dead by the time firefighters arrived. A male victim was outside the house as crews arrived and reported that a person was trapped inside. SFD said the second victim was taken to Harborview for treatment of smoke inhalation.

UPDATE: A SFD spokesperson said investigators have determined the cause of the fire to be improperly discarded smoking materials that ignited a chair inside the house. The fire did an estimated $200,000 in damage to the structure and its contents. UPDATE x2: SFD has also posted an update saying a family pet was found safe at a neighbor’s house following the fire and that the Red Cross was called in to provide shelter assistance for the second victim after he was released from the hospital and a caregiver living in the home.

Charred damage to the side of the 1902-built house was visible as smoke billowed from the front windows. A neighbor tells CHS the woman who died was a 92-year-old owner of the house. SFD has confirmed that her 76-year-old son was the second victim transported to the hospital for treatment for smoke inhalation and minor burns.

Neighbor Eric provided this photo and a few details:“My friend called it in. We were waiting for the 10 on 15th and Republican when we noticed white smoke beginning to build behind QFC. He then called and in the process, the smoke started to blacken. A minute after this photo was taken, the fire department arrived.”
