MARYSVILLE — According to fire officials, flames had fully engulfed a home at 3817 64th Ave. NE when firefighters arrived on the scene about 9:38 a.m. June 30.

The flames also had spread from the two-story home to a neighboring house, according to Marysville Fire District Public Information Office Stephanie Price.

Price said firefighters fought a defensive battle against the flames in the first home, while working to douse the secondary fire in the house next door.

Emergency personnel searched both homes and were able to determine no one was in either structure. They did rescue a dog from the home to which the fire had spread.

According to Price, the flames were extinguished by about 10:26 a.m.

Besides the Marysville Fire District, firefighters from Lake Stevens, Getchell, Tulalip Bay and Everett also responded to the scene. Three engine companies, one ladder company, three aid companies and the on-duty battalion chief all were dispatched to the fire.

Following the incident, two firefighters were taken to a local hospital as a precaution. One was treated for what was described by Price as minor neck and back pain, while another suffered from heat exhaustion.

The Snohomish County Fire Marshal is investigating the cause of the fire. Damage loss was unknown June 30.

Price said neighbors reported seeing lots of smoke coming from the front porch area of the first home and heard popping noises, then called 911. After calling for help, neighbors pounded on doors of nearby homes in effort to alert anyone in those homes of the possible danger.
