MARYSVILLE — Arson appears to be the cause of a recent residential fire in Marysville.

At 10:29 p.m. on Tuesday, Jan. 3, the Marysville Fire District was dispatched to a residential fire in the 6700 block of 40th Street NE. Firefighters arrived at 10:34 p.m. and located a fire in a single-story residential structure.

Original reports stated the house was “on fire with smoke and crackling sounds.” The first arriving captain reported a one-story well-involved residential structure. Firefighters fought the fire defensively and the fire was under control within 30 minutes, confined to the structure, which was vacant. No firefighter injuries were reported.

The fire’s dollar loss has been estimated at $70,000.

At the height of the incident, more than 18 firefighters battled the blaze with mutual aid provided by Lake Stevens Fire District 8.

The fire was investigated by the Marysville Fire District Fire Marshal’s Office and the Marysville Police Department, and the cause has been determined to be arson.

The Marysville Fire District and the Marysville Police Department encourage residents to be vigilant in watching vacant properties to reduce potential acts of arson.
