An Oak Harbor man perished in an apartment fire early Tuesday morning, according to a press release from the Oak Harbor Fire Department.

Island County Coroner Shantel Porter said the man’s name won’t be released until his family is notified. She said an autopsy to determine the cause of death will be performed later this week.

Oak Harbor Fire Chief Travis Anderson said the cause of the fire is under investigation.

“Our thoughts are with the family and loved ones of the victim,” he said. “We are grateful to our partner agencies for their quick response and assistance on scene.”

At about 12:46 a.m., crews from the Oak Harbor Fire Department responded to reports of a structure fire at 830 Northwest Rigging Street. Multiple 911 callers reported heavy flames visible from an apartment complex, according to the press release.

While en route, responding units were updated that flames were coming through the roof of the structure. Oak Harbor Fire Department personnel arrived on scene within six minutes of dispatch. Mutual aid units from North Whidbey Fire and Rescue and the Navy fire department also responded, with all units on scene within 11 minutes.

Upon arrival, firefighters encountered significant fire involvement in a second-story apartment. Crews acted swiftly to conduct searches and evacuate the remaining three units in the building. Due to the intensity of the fire in the originating apartment, an initial search was not possible.

After the fire was brought under control, crews conducted a thorough search of the affected apartment, where they discovered one adult victim deceased, the fire department reported.

No firefighter injuries were reported, and all evacuated residents from adjacent units are safe.
